In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for the description of the embodiments will be briefly described below, and it is apparent that the drawings in the following description are only some embodiments of the present application, and other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of an imaging control method according to an embodiment of the application. The imaging control method is applied to a host in medical imaging equipment. By way of example, the medical imaging device may include: a host, and an image forming apparatus connected to the host. The imaging device is provided with an imaging area, and the host can control the imaging device to image objects in the imaging area. The imaging control method may include:
step 101, after a target part of a user is located in an imaging area of the medical imaging device, controlling an imaging device in the medical imaging device to execute shooting operation on the target part until shooting stop conditions are met.
Fig. 2 is a flowchart of a photographing operation according to an embodiment of the present application, as shown in fig. 2. The photographing operation may include:
and step 1011, controlling the imaging device to start shooting the target part when the user is determined to be in a breath-hold state.
Step 1012, when it is determined that the user is in the non-breath-hold state, controlling the imaging device to pause shooting the target part.
The target site may be a lung of the user. When the user is breathing out after inhaling, the user is in a breath-hold state, and the movement amplitude of the lung of the user is small. When the user exhales or inhales, the user is in a non-breath-hold state, and the movement amplitude of the lung of the user is large. Because the host in the medical imaging equipment can determine that the imaging device starts shooting the lung when the user is in a breath-hold state, and controls the imaging device to pause shooting the lung when the user is determined to be in a non-breath-hold state. Therefore, the medical imaging device has better effect of subsequently acquiring the image containing the lung of the user.
Step 102, generating an image corresponding to the target portion based on the captured projection data.
In the embodiment of the application, after the photographing of the target part of the user by the medical imaging device meets the photographing stop condition, the medical imaging device can acquire the projection data obtained by photographing and generate the image corresponding to the target part of the user based on the projection data.
In summary, in the imaging control method provided by the embodiment of the present application, in a process that the imaging device in the medical imaging apparatus performs a shooting operation on a target portion of a user, the host in the medical imaging apparatus can control the imaging device to start shooting the target portion after determining that the user is in a breath-hold state, and the host can also control the imaging device to suspend shooting the target portion after determining that the user is in a non-breath-hold state. Therefore, the problem that the definition of the image containing the target part is lower when the imaging device shoots the target part with larger movement amplitude can be avoided, and the imaging quality of the medical imaging equipment is effectively improved. Further, since the imaging device in the medical imaging apparatus photographs the target portion of the user only when the user is in the breath-hold state, the target portion of the user is not photographed when the user is in the non-breath-hold state. Therefore, the radiation quantity generated by the imaging device on the user can be effectively reduced.
Alternatively, in the above step 101, after the target portion of the user is located in the imaging area of the medical imaging apparatus, the host computer in the medical imaging apparatus may control the photographing operation performed on the target portion by the imaging device. In the process that the imaging device performs the shooting operation on the target portion, if the host determines that the shooting of the target portion by the imaging device meets the shooting stop condition, the host may control the imaging device to stop shooting the target portion, and execute step 102.
In an embodiment of the present application, the photographing stop condition may include: at least one of a condition that a photographing time period of the imaging device for the target portion is longer than a photographing time period threshold value, and a condition that a photographing frequency of the imaging device for the target portion is greater than a photographing frequency threshold value.
For example, when the shooting time period of the imaging device to the target part is longer than the shooting time period threshold, the shooting of the imaging device to the target part can meet the shooting stop condition; or when the shooting frequency of the imaging device to the target part is larger than the shooting frequency threshold value, the shooting of the imaging device to the target part can meet the shooting stop condition; or when the shooting time of the imaging device to the target part is longer than the shooting time threshold and the shooting frequency of the imaging device to the target part is greater than the shooting frequency threshold, the shooting of the imaging device to the target part can meet the shooting stop condition.
It should be noted that, according to the function of the medical imaging device, at least one of the shooting frequency threshold and the shooting duration threshold may be set, so that after the imaging device in the medical imaging device shoots the target part and meets the shooting stop condition, the medical imaging device can acquire the image with the corresponding function subsequently.
In the present application, the host computer in the medical imaging device determines that the user is in a breath-hold state or a non-breath-hold state in various implementation manners, and the following two alternative implementation manners in the embodiment of the present application are schematically illustrated as examples:
in a first alternative implementation manner, in a process that an imaging device in the medical imaging device performs a shooting operation on a target part of a user, the user triggers different control instructions by itself, so that when a host in the medical imaging device acquires the different control instructions triggered by the user, a current user is determined to be in a breath-hold state or a non-breath-hold state.
For this reason, the photographing operation performed by the host in the medical imaging apparatus in the embodiment of the present application may further include: when a shooting starting instruction triggered by a user is acquired, determining that the user is in a breath-hold state; when a shooting suspension instruction triggered by a user is acquired, the user is determined to be in a non-breath-hold state.
In an embodiment of the present application, the medical imaging apparatus has a control button. The user can perform a first operation on the control button to trigger a shooting start instruction; the user may also perform a second operation on the control button to trigger a pause shooting instruction.
In this case, when the shooting start instruction triggered by the user is acquired in the shooting operation, determining that the user is in the breath-hold state may include: when the first operation of the control button by the user is acquired to trigger a shooting start instruction, the target part is determined to be in a static shooting state. When a pause shooting instruction triggered by a user is acquired in the shooting operation, determining that the user is in a non-breath-hold state may include: and when the second operation of the control button by the user is acquired to trigger the shooting suspension instruction, determining that the user is in a non-breath-hold state.
Alternatively, the first operation performed by the user on the control button may be: long-press operation is carried out on the control button; the second operation of the control button by the user may be: the stop pressing operation performed on the control button, that is, the control button is not pressed. Thus, when the user presses the control button for a long time, the shooting start instruction can be triggered; when the user stops pressing the control button for a long time, the shooting suspension instruction can be triggered. In other alternative implementations, the first operation performed by the user on the control button may also be: a pressing operation of the control button is performed once during a process of suspending shooting by the medical imaging device; the second operation performed by the user on the control button may also be: in photographing by the medical imaging apparatus, one pressing operation of the control button is performed. Of course, the first operation and the second operation performed by the user on the control button may be other types of pressing operations, which are not limited in the embodiment of the present application.
It should be noted that the control button in the medical imaging device may be integrated in a handheld device, which may be connected to a host computer in the medical imaging device. In the process of the medical imaging device performing photographing operation on the target portion of the user, the user can hold the handheld device so that the user can perform the first operation or the second operation on the control button in the handheld device.
By way of example, it is assumed that the target site of the user is the lungs, i.e., the medical imaging apparatus is required to image the lungs of the user. After the user's lungs are located within the imaging area of the medical imaging device, a host in the medical imaging device may control the imaging apparatus to perform a photographing operation on the user's lungs. In the process of executing shooting operation, when a user is in a breath-hold state, namely when the used lung is in the breath-hold state, the user can perform a first operation on a control button to trigger a shooting starting instruction, a host in the medical imaging equipment determines that the lung of the user is in the breath-hold state after acquiring the shooting starting instruction, and controls an imaging device to start shooting the lung of the user; when the user needs to breathe, namely the lung to be used is about to be changed from a breath-hold state to a non-breath-hold state, the user can perform a second operation on the control button to trigger a shooting suspension instruction, a host in the medical imaging equipment determines that the lung of the user is in the non-breath-hold state after acquiring the shooting suspension instruction, and controls the imaging device to suspend shooting of the lung of the user.
In the first alternative implementation manner, when the host computer in the medical imaging device acquires the shooting start instruction triggered by the user, the host computer does not need to execute the action of determining that the user is in the breath-hold state, but directly performs the action of controlling the imaging device to start shooting the target part of the user. When a host in the medical imaging device acquires a pause shooting instruction triggered by a user, the host does not need to execute the action of determining that the user is in a non-breath-hold state, but directly executes the action of controlling the imaging device to pause shooting of a target part of the user.
In a second alternative implementation manner, in a process that an imaging device in the medical imaging device performs shooting operation on a target part of a user, by setting the operation time length of the medical imaging device, a host in the medical imaging device determines whether a current user is in a breath-hold state or a non-breath-hold state.
For this reason, the photographing operation performed by the host in the medical imaging apparatus in the embodiment of the present application may further include: after an imaging device in the medical imaging equipment continuously shoots a target part of a user for a first time period, determining that the user is in a breath-hold state; after the imaging device in the medical imaging equipment continuously pauses shooting of the target part of the user for a second time period, the user is determined to be in a non-breath-hold state.
In an embodiment of the present application, in order to enable a user to more accurately control a target portion of the user, a photographing operation performed by a host in the medical imaging apparatus may further include: generating first prompt information after determining that the user is in a non-breath-hold state; and generating second prompt information after determining that the user is in the breath-hold state. The first prompt information is used for indicating that shooting starts after a second time period is elapsed, and the second prompt information is used for indicating that shooting is paused after the first time period is elapsed.
It should be noted that, the first prompt information and the second prompt information may be at least one of voice prompt information and text prompt information.
In the present application, when the first prompt information and the second prompt information are both voice prompt information, the medical imaging apparatus may have an audio player connected with the host computer. After the host computer in the medical imaging equipment determines that the user is in a non-breath-hold state, the host computer sends out first prompt information through the audio player, and the user can control the target part to be converted into the breath-hold state from the non-breath-hold state after the second time length passes according to the first prompt information. After the host computer in the medical imaging equipment determines that the user is in a breath-hold state, the host computer sends out second prompt information through the audio player, and the user can control the target part to be converted into a non-breath-hold state from the breath-hold state after the first time length passes according to the second prompt information.
When the first prompt message and the second prompt message are both text prompt messages, the medical imaging device may have a display connected with the host computer. After the host computer in the medical imaging equipment determines that the user is in the non-breath-hold state, the host computer displays the first prompt information through the display, and the user can control the target part to be converted into the breath-hold state from the non-breath-hold state after the second time length passes according to the first prompt information. After the host computer in the medical imaging equipment determines that the user is in a breath-hold state, the host computer displays second prompt information through the display, and the user can control the target part to be converted into a non-breath-hold state from the breath-hold state after the first time length passes according to the second prompt information.
In an embodiment of the present application, the photographing operation performed by the host in the medical imaging apparatus may further include: after the target part of the user is positioned in the imaging area, generating first prompt information, and shooting the target part of the user after the second time period.
For example, the medical imaging device may have a body detection assembly coupled to a host computer that may detect whether a target site of a user is located within an imaging zone of the medical imaging device via the body detection assembly. If the human body detection assembly detects that the target part of the user is located in the imaging area, the host computer can generate first prompt information and control the imaging device to shoot the target part after the second time. And then, the host computer can control the imaging device to pause shooting the target part after continuously shooting the first time period, and control the imaging device to start shooting the target part after continuously pausing shooting the second time period. After shooting of the target part of the imaging device meets shooting stop conditions, the host can control the imaging device to stop shooting of the target part.
The following embodiments will describe the shooting process of the lungs in combination with the second alternative described above, assuming that the target site of the user is the lungs. After the host in the medical imaging equipment detects that the lung of the user is positioned in the imaging area of the medical imaging equipment through the human body detection component, the host can generate first prompt information, the user can continuously breathe according to the prompt of the first prompt information and conduct screen information after a second time period, and the host in the medical imaging equipment can control the imaging device to shoot the lung of the user after the second time period. Before the host computer controls the imaging device to shoot the lung of the user, the host computer can generate second prompt information, and the user can start to hold breath and keep holding the breath for at least a first duration according to the prompt of the second prompt information. After the host controls the imaging device to continuously shoot the lungs of the user for a first period of time, the host determines that the lungs of the user are in a non-breath-hold state (namely, the user starts to breathe) and generates first prompt information, and controls the imaging device to pause shooting the lungs of the user, so that the user can start to breathe according to the prompt of the first prompt information and hold breath after continuously breathing for a second period of time. After the imaging device continuously pauses shooting the lungs of the user for a second duration, the host computer determines that the lungs of the user are in a breath-hold state (namely, the user starts to hold the breath), generates second prompt information, controls imaging to start shooting the lungs of the user, and can start to hold the breath according to the prompt of the second prompt information and starts to breathe after the user keeps holding the breath-hold for at least the first duration.
It should be noted that, in the second alternative implementation manner, after the host computer in the medical imaging device determines that the imaging device continuously shoots the target portion of the user for the first period, the host computer does not need to perform the action of determining that the user is in the non-breath-hold state, but directly performs the action of controlling the imaging device to pause shooting the target portion of the user, and generates the first prompt message. After the host in the medical imaging equipment determines that the imaging device continuously pauses shooting of the target part of the user for a second time period, the host does not need to execute the action of determining that the user is in a breath hold state, but directly executes the action of controlling the imaging device to start shooting of the target part of the user and generates a second prompt message.
In the embodiment of the present application, when the host in the medical imaging device determines that the user is in the breath-hold state or the non-breath-hold state, the host in the medical imaging device needs to acquire the first duration and the second duration by implementing the second optional implementation manner. The first duration may be a duration in which the user is in a breath-hold state, and the second duration may be a duration in which the user is in a non-breath-hold state.
In one exemplary implementation, the first time period may be obtained by counting a duration of time that each user of the population is in a breath-hold state, and the second time period may be obtained by counting a duration of time that each user of the population is in a non-breath-hold state.
In another exemplary implementation, the first time period is determined based on a duration of time that the user is in a breath-hold state, and the second time period is determined based on a duration of time that the user is in a non-breath-hold state. For example, before the host computer in the medical imaging apparatus controls the imaging device to perform a photographing operation on a target site of a user, the imaging control method may further include: acquiring a first duration of time that a user is in a breath-hold state continuously and a second duration of time that the user is in a non-breath-hold state continuously; based on the first duration and the second duration, a first duration and a second duration are generated. Wherein the first duration is less than or equal to the first duration and the second duration is less than or equal to the second duration. In this case, the corresponding first duration and second duration may be set for each user's own situation, so that the quality of the image obtained after the shooting of the target portion of the user may be further improved.
For example, a host in a medical imaging device may be connected to a duration acquisition device. The acquiring the first duration that the user is continuously in the breath-hold state and the second duration that the user is continuously in the non-breath-hold state in the above embodiment may include: and receiving a first duration and a second duration which are sent by the duration acquisition equipment and are triggered by a user on the duration acquisition equipment. It should be noted that, since there are a plurality of kinds of duration acquisition devices connected to the host in the medical imaging device, and for different kinds of duration acquisition devices, the manner in which the host in the medical imaging device acquires the first duration and the second duration is also different. Thus, embodiments of the present application are schematically illustrated in two realizations:
in a first implementation, the duration acquisition device may be a control panel in the medical imaging device in which a window for inputting duration information may be displayed.
First, the user generally tests himself for a first duration of time in a breath-hold state and for a second duration of time in a non-breath-hold state. The user may then enter the first duration and the second duration within a window in the control panel. Finally, the control panel may send the first duration and the second duration entered by the user to a host in the medical imaging device such that the first duration and the second duration can be acquired by the host in the medical imaging device.
In a second implementation manner, the duration acquiring device may be a terminal, and a communication connection is established between the terminal and the medical imaging device.
In one case, a window may be displayed on the display interface of the terminal, and the function of the window may be the same as the function of the window displayed by the control panel in the first implementation manner, so that the user may input the first duration and the second duration into the window in a more self-situation. In this case, the manner in which the host in the medical imaging device obtains the first duration and the second duration may refer to the corresponding content in the first realizable manner, and the present application is not described herein again.
In another case, a detection button may be displayed on the display interface of the terminal. The terminal can detect different instructions triggered by different operations of the detection button by a user to acquire the first duration and the second duration.
For example, the manner in which the terminal obtains the first duration and the second duration may include: after detecting a third operation of the detection button by a user to trigger a first instruction, recording a first moment; after detecting a fourth operation of the detection button by the user to trigger a second instruction, recording a second moment; after detecting that a user performs a third operation on the detection button to trigger the first instruction, recording a third moment; the time period between the first time and the second time is determined as a first duration, and the time period between the second time and the third time is determined as a second duration.
In the embodiment of the application, after the terminal acquires the first duration and the second duration, the first duration and the second duration can be sent to a host in the medical imaging equipment, so that the host in the medical imaging equipment can acquire the first duration and the second duration. It should be noted that, in order to improve accuracy of acquiring the first duration and the second duration by the terminal, the terminal may perform a process of acquiring the first duration and the second duration multiple times, take an average value of the acquired multiple first durations as a final first duration, take an average value of the acquired multiple second durations as a final second duration, and may send the final first duration and the final second duration to a host in the medical imaging device.
Optionally, the third operation performed by the user on the detection button may be: long-press operation is carried out on the detection button; the fourth operation of the detection button by the user may be: the stop pressing operation performed on the detection button, that is, the detection button is not pressed. Thus, when the user presses the detection button for a long time, the first instruction can be triggered; when the user stops pressing the detection button for a long time, the second instruction can be triggered. In other alternative implementations, the third operation and the fourth operation performed by the user on the detection button may be other types of pressing operations, which are not limited in the embodiment of the present application.
By way of example, it is assumed that the target site of the user is a lung, i.e. the imaging device in the medical imaging apparatus is required to image the lung of the user. Before the imaging device performs a photographing operation on the user's lungs, the user needs to perform a process of acquiring the first duration and the second duration on the terminal. For example, when the user is in a breath-hold state, that is, when the used lung is in a breath-hold state, the user may perform a third operation on the detection button to trigger a first instruction, and the terminal records a first moment when the first instruction is detected; when the user needs to breathe, namely the used lung is about to change from a breath-hold state to a non-breath-hold state, the user can perform a fourth operation on the detection button to trigger a second instruction, and the terminal records a second moment when detecting the second instruction; when the user enters a breath-hold state after breathing, namely when the used lung is about to change from a non-breath-hold state to a breath-hold state, the user can perform a third operation on the detection button to trigger a first instruction, and the terminal records a third moment after detecting the first instruction. The terminal may then determine a duration between the first time and the second time as a first duration and a duration between the second time and the third time as a second duration.
In the related art, when a target portion (for example, a lung) of a user needs to be photographed, the user needs to cooperate with an operator of the medical imaging apparatus. For example, when an operator lets a user hold a breath, the user needs to keep the breath hold state, and the operator controls the medical imaging apparatus to take a photograph of the user's lungs; when the operator breathes the user, the user can stop holding breath and breathe, and the operator controls the medical imaging device to pause shooting the lungs of the user. However, the operator cannot accurately evaluate the vital capacity of the user, and a breathing phenomenon of the user due to the inability to maintain a breath-hold state is likely to occur during photographing of the lungs of the user by the medical imaging apparatus. In this way, the resulting image of the lungs of the user obtained by the medical imaging apparatus is blurred.
In the embodiment of the application, the host in the medical imaging device can automatically determine whether the user is in the breath-hold state or the non-breath-hold state through the two optional implementation modes, after the user is determined to be in the breath-hold state, the host in the medical imaging device can control the imaging device to start shooting the target part, and after the user is determined to be in the non-breath-hold state, the host in the medical imaging device can control the imaging device to pause shooting the target part. And the host in the medical imaging equipment is triggered by the user without intervention of the operator when determining whether the user is in a breath-hold state or a non-breath-hold state. Thus, the target part of the user can be always in a breath-hold state in the process of shooting the target part of the user by the imaging device of the medical imaging equipment. Because of the imaging control method provided by the embodiment of the application, a user can finish imaging the target part in the medical imaging equipment by himself, and the automatic imaging can be realized without intervention of an operator. The imaging control method is applied to the scene of imaging the target part of the user suffering from infectious diseases, so that the risk of infection of the operator can be effectively reduced.
In summary, in the imaging control method provided by the embodiment of the present application, in a process that the imaging device in the medical imaging apparatus performs a shooting operation on a target portion of a user, the host in the medical imaging apparatus can control the imaging device to start shooting the target portion after determining that the user is in a breath-hold state, and the host can also control the imaging device to suspend shooting the target portion after determining that the user is in a non-breath-hold state. Therefore, the problem that the definition of the image containing the target part is lower when the imaging device shoots the target part with larger movement amplitude can be avoided, and the imaging quality of the medical imaging equipment is effectively improved. Further, since the imaging device in the medical imaging apparatus photographs the target portion of the user only when the user is in the breath-hold state, the target portion of the user is not photographed when the user is in the non-breath-hold state. Therefore, the radiation quantity generated by the imaging device on the user can be effectively reduced.
The embodiment of the application also provides medical imaging equipment, which can comprise: a processor, and a memory for storing executable instructions of the processor. Wherein the processor is configured to perform the imaging control method described above. For example, the imaging control method may be the imaging control method shown in fig. 1. It should be noted that, the processor and the memory in the medical imaging apparatus may be integrated in the host.
Optionally, the medical imaging apparatus further includes: a control button connected with the processor. The processor is further configured to: when a first operation of a control button by a user is acquired to trigger a shooting start instruction, determining that the user is in a breath hold state; and when the second operation of the control button by the user is acquired to trigger the shooting suspension instruction, determining that the user is in a non-breath-hold state.
In the embodiment of the application, the medical imaging device can be a CT device, a CBCT device, an MRI device or a vertical CBCT device, etc. In addition, the following embodiments will be schematically described taking a medical imaging apparatus as an example of a vertical CBCT apparatus.
As shown in fig. 3, fig. 3 is a schematic structural view of a medical imaging apparatus according to an embodiment of the present application. The medical imaging device may further include: first frame 100, second frame 200, bulb 300, detector 400, first rotor 500, second rotor 600, and a drive assembly (not shown). The bulb 300 and the detector 400 can constitute an imaging device in a medical imaging apparatus.
Wherein the bulb 300 may be mounted on the first housing 100 and the detector 400 may be mounted on the second housing 200. Also, a probe 400 in the medical imaging apparatus 000 is disposed opposite the bulb 300, and a region between the probe 400 and the bulb 300 is an imaging region of the medical imaging apparatus. When it is desired to image a target site of a user, the target site needs to be located within the imaging zone. In the present application, the detector 400 may be a flat panel detector, which is generally manufactured at a low cost. Alternatively, the flat panel detector may be a dual layer flat panel detector. After the X-rays emitted from the bulb tube 300 penetrate the target object, the dual-layer flat panel detector can acquire high-energy projection data and low-energy projection data and generate two images with different energy levels. Because the two images with different energy levels have advantages on the imaging of soft tissues and bones in the target object, the subsequent clinical diagnosis according to the two images with different energy levels has better effect.
The first rotation body 500 may be located between the first frame 100 and the second frame 200, and the first rotation body 500 is not connected to either the first frame 100 or the second frame 200. The first revolving unit 500 can revolve with respect to the first frame 100 and the second frame 200.
The second revolving body 600 may be fixedly connected to the first frame 100 and the second frame 200, respectively, and the second revolving body 600 may drive the first frame 100 and the second frame 200 to revolve at the same time.
The drive units are connected to the first revolving unit 500 and the second revolving unit 600, respectively. The driving assembly is used for driving the first revolving body 500 to revolve along a first direction and driving the second revolving body 600 to revolve along a second direction, so that the bulb 300 and the detector 400 revolve at a target part in an imaging region. For example, the first direction may be one of a clockwise direction and a counterclockwise direction, and the second direction may be the other of the clockwise direction and the counterclockwise direction. Therefore, the imaging time of the medical imaging equipment can be shortened, the imaging efficiency of the medical imaging equipment can be improved, and the radiation dose of a patient to the medical imaging equipment can be reduced.
In the present application, the first rotator 500 may have a columnar shape, and for example, the bottom surface of the first rotator 500 may have a circular shape. In this manner, the first rotator 500 is capable of carrying a user, and the user's target site may be located within the imaging region while the user is located on the first rotator 500. The second rotator 600 may have a ring shape, and for example, the bottom surface of the second rotator 600 may have a circular ring shape. In this way, the first rotator 500 can rotate by the user on the first rotator 500 under the driving of the driving component, and the first rotator 500 is relatively stationary with respect to the user during the rotation process. The second rotator 600 can reversely rotate around the user under the driving of the driving unit.
In the embodiment of the present application, the first revolving body 500 and the second revolving body 600 are both located on the first reference surface, and the first revolving body 500 is located in the area surrounded by the second revolving body 600, and the first revolving body 500 and the second revolving body 600 can be movably connected with respect to the first reference surface. Here, the first rotation body 500 may be flush with the surface of the second rotation body 600 and the first reference surface S, thus facilitating patient walking.
In another possible implementation, the first revolving body 500 may be located on a first reference surface, the second revolving body 600 may be located on a second reference surface disposed opposite to the first reference surface, and the first revolving body 500 may be movably connected with respect to the first reference surface, and the second revolving body 600 may be movably connected with respect to the second reference surface. When the medical imaging device is located in the treatment room, the first reference surface in the embodiment of the application refers to the ground of the treatment room, and the second reference surface refers to the surface of the ceiling of the treatment room.
In the present application, the driving unit may drive the first revolving unit 500 to revolve around the rotation axis L1 of the first revolving unit 500 in the first direction, and the rotation axis L1 may coincide with the central axis of the first revolving unit 500. The driving assembly may drive the second rotator 600 to rotate around a rotation axis L2 of the second rotator 600 in the second direction, and the rotation axis L2 may coincide with a central axis of the second rotator 600. Wherein the rotation axis L1 of the first rotation body 500 is collinear with the rotation axis L2 of the second rotation body 600.
It should be noted that, when only one two-dimensional image of the target object needs to be acquired at one shooting angle, the bulb 300 and the detector 400 do not need to rotate relative to the target object in the imaging area, and thus, the driving assembly does not need to drive the first rotator 500 and the second rotator 600 to rotate. When multiple two-dimensional images of the target object are required to be acquired at multiple shooting angles, the bulb 300 and the detector 400 need to rotate relative to the target object in the imaging area, and thus the driving assembly needs to drive the first rotation body 500 and the second rotation body 600 to rotate. When a three-dimensional image of a target object needs to be acquired, the driving assembly needs to drive the first rotator 500 and the second rotator 600 to rotate, and needs to ensure that the bulb tube 300 and the detector 400 both need to rotate at least one complete circle relative to the target object in the imaging area, so that a three-dimensional image corresponding to the target object can be obtained after three-dimensional reconstruction is performed on a plurality of two-dimensional images acquired at different shooting angles.
In the present application, in the process of imaging a target portion in an imaging area by using the bulb 300 and the detector 400 (i.e., the imaging device) in the medical imaging apparatus, if the bulb 300 and the detector 400 need to rotate relative to the target object in the imaging area, the rotation direction of the first rotator 500 is opposite to the rotation direction of the second rotator 600, so that the rotation speed of the bulb 300 and the detector 400 relative to the target object in the imaging area is higher, and the imaging efficiency of the medical imaging apparatus is effectively improved. In order to ensure that the medical imaging apparatus can acquire images with higher quality, it is necessary to ensure that the speed of the driving assembly when driving the first rotator 500 and the second rotator 600 to rotate is low. For example, when the driving assembly rotates the first rotator 500 and the second rotator 600, the rotation angle per second needs to be less than 7 degrees.
In an embodiment of the present application, the medical imaging apparatus may photograph a target site within an imaging region through the bulb 300 and the probe 400. The drive assembly in the medical imaging device may be configured to: when the bulb 300 and the detector 400 start shooting the target part in the imaging area, the first rotation body 500 and the second rotation body 600 are controlled to rotate; when the bulb 300 and the detector 400 suspend photographing the target portion in the imaging area, the first rotation body 500 and the second rotation body 600 are controlled to suspend rotation. In this way, when the bulb 300 and the detector 400 start shooting the target part, the bulb 300 and the detector 400 can shoot at different shooting angles, and the phenomenon that shooting cannot be performed at a certain shooting angle due to the fact that the first revolving body 500 and the second revolving body 600 still rotate when the bulb 300 and the detector 400 pause shooting the target part is avoided.
Alternatively, as shown in fig. 4, fig. 4 is a schematic structural diagram of another medical imaging apparatus according to an embodiment of the present application. The medical imaging device may further include: patient support 700. The patient support 700 may be positioned between the first gantry 100 and the second gantry 200, and the patient support 700 is configured to support a patient. For example, the patient support 700 may be a chair and a patient may sit on the patient support 700; the patient support 700 may also be a bed and a patient may lie on the patient support 700. In the present application, the first rotation body 500 in the medical imaging apparatus may be fixedly connected to the patient support 700.
Alternatively, a drive assembly in a medical imaging device may include: a drive motor (not shown) and at least one transmission (not shown). The at least one transmission may include: a first transmission mechanism for connecting the drive motor and the first rotation body 500, and a second transmission mechanism for connecting the drive motor and the second rotation body 600.
Wherein, the driving assembly can drive the first revolving body 500 to rotate through the driving motor and the first transmission mechanism; the driving assembly can also drive the second revolving body 600 to rotate through the driving electrode and the second transmission mechanism.
It should be noted that each transmission mechanism in the driving assembly includes, but is not limited to: a gear pair transmission mechanism, a belt transmission mechanism or a gear rack transmission mechanism, etc.
In an embodiment of the present application, the first gantry 100 and the bulb tube 300 in the medical imaging apparatus may be fixedly connected, and the second gantry 200 and the detector 400 may be fixedly connected.
In other alternative implementations, the medical imaging device may further include: a first slide assembly (not shown) coupled to the first housing 100 and the bulb 300, respectively, and a second slide assembly (not shown) coupled to the second housing 200 and the detector 400, respectively. The first sliding component is used for driving the bulb 300 to move on the first frame 100, for example, the bulb 300 can move along the length direction of the first frame 100 through the first sliding component; the second sliding component is used to drive the detector 400 to move on the second rack 200, for example, the detector 400 may be moved along the length direction of the second rack 200 by the second sliding component.
In this case, by sliding the bulb 300 on the first housing 100 and sliding the probe 400 on the second housing 200, adjustment of the position of the imaging region in the medical imaging apparatus 000 can be achieved, so that the medical imaging apparatus 000 can image any part of the patient.
The embodiment of the application also provides an imaging system, as shown in fig. 5, fig. 5 is a schematic structural diagram of the imaging system provided by the embodiment of the application, and the imaging system may include: a treatment room 001 and a medical imaging device 000. The medical imaging apparatus 000 may be the medical imaging apparatus in the above-described embodiment, and for example, the medical imaging apparatus 000 may be the medical imaging apparatus shown in fig. 3 or fig. 4.
Alternatively, as shown in fig. 6, fig. 6 is a schematic structural diagram of another imaging system according to an embodiment of the present application. The imaging system may further include: a terminal 002 communicatively connected to a host in the medical imaging apparatus 000.
Optionally, the patient may simulate the imaging control method described above through an application program in the terminal 002 or a virtual reality device (e.g., VR glasses, helmets, etc.), and train breath-hold and breath in advance to control the imaging device to perform imaging acquisition or pause imaging acquisition.
Optionally, the imaging system may further include: a server which can be communicatively connected to the host in the medical imaging apparatus 000 and the terminal 002, respectively, so that the terminal 002 can be communicatively connected to the host in the medical imaging apparatus 000 through the server.
In the present application, the terminal 002 is configured to: the first duration and the second duration triggered by the user on terminal 002 are sent to the host in the medical imaging device 000. The first duration is a duration that the user is continuously in a breath-hold state, and the second duration is a duration that the user is continuously in a non-breath-hold state. As such, the host in the medical imaging device 000 may set a first duration for which the medical imaging device 000 continuously photographs a target portion of a user and a second duration for which the medical imaging device 000 continuously pauses photographing the target portion of the user after receiving the first duration and the second duration, so that the host in the medical imaging device 000 can control the imaging apparatus to perform a photographing operation on the target portion of the user.
For example, the detection button is displayed on the display interface of the terminal 002. The terminal 002 is configured to: after detecting that a user performs a third operation on the detection button to trigger a first instruction, recording a first moment; recording a second moment after detecting that a user performs a fourth operation on the detection button to trigger a second instruction; after detecting that a user performs a third operation on the detection button to trigger the first instruction, recording a third moment; the time period between the first time and the second time is determined as a first duration, and the time period between the second time and the third time is determined as a second duration.
In an embodiment of the present application, as shown in fig. 7, fig. 7 is a schematic structural diagram of yet another imaging system according to an embodiment of the present application. The imaging room 001 in the imaging system has a first automatic door 001a. The imaging system may further include: a control device (not labeled in the figure) and an authentication device 004. The control device may be integrated in a host in the medical imaging device 000, or may be a separate device located outside the host in the medical imaging device 000. The control device may be connected to the authentication device 004 and the first automatic door 001a, respectively. The authentication device 004 may be located outside the imaging chamber 001. The control device is configured to: after the authentication information of the user is successfully authenticated by the authentication device 004, the first automatic door 001a is controlled to be opened, and the first automatic door 001a is controlled to be closed after the first automatic door 001a is opened for a preset period of time.
For example, when a user needs to image a target portion of the user through the imaging system, the user may reserve in an application program installed on the terminal, and after the reservation is successful, the terminal may generate identity information of the user, where the identity information may include: the name, sex, identification number, and time period information of using the medical imaging apparatus, etc. of the user.
In one case, the authentication device 004 may include a scanning component. After the user makes a reservation on the terminal, the terminal can generate a two-dimensional code or a bar code corresponding to the identity information of the user. Thus, the scanning component can acquire the identity information of the user by scanning the two-dimensional code or the bar code provided by the user.
In another case, the authentication device 004 may include a biometric acquisition component. After the user has successfully reserved on the terminal, the user also needs to enter the biometric features (such as fingerprint, voiceprint or face) of the user on the terminal. Thus, the biometric acquisition component can acquire the identity information of the user by acquiring the biometric of the user.
After the identity verification device 004 obtains the identity information of the user, the identity information of the user can be verified, and after the verification is successful, the control device can control the first automatic door 001a to be opened so as to enable the user to enter the imaging room 001. After the authentication failure, the control device does not control the first automatic door 001a to open.
In the embodiment of the present application, the imaging room 001 in the imaging system has a second automatic door 001b. The second automatic door 001b may be connected to a control device. The control device is further configured to: after photographing of the target portion of the user by the medical imaging apparatus 000 is completed, the second automatic door 001b is controlled to be opened, and the second automatic door 001b is controlled to be closed after the second automatic door 001b is opened for a preset period of time.
For example, the control device may be further connected to the medical imaging device 000, and the medical imaging device 000 may transmit a photographing completion instruction to the control device after photographing operation of the medical imaging device 00 on a target site of a user satisfies a photographing stop condition. The control device may control the second automatic door 001b to be opened after receiving the photographing completion instruction, and control the second automatic door 001b to be closed after the second automatic door 001b is opened for a preset period of time.
In an embodiment of the present application, the imaging system may further include: a voice prompt device (not shown) located inside the imaging room 001 and outside the imaging room 001, which can emit voice prompt audio for indicating the way of use of the imaging system to the user. Thus, the user enters the imaging room 001 through the first automatic door 001a by himself through the voice prompt audio sent by the voice prompt device, and images the target part of the user through the medical imaging equipment 000 in the imaging room 001, and then goes out from the imaging room 001 through the second automatic door 001b by himself after the imaging is completed. When the imaging system is applied to a scene of epidemic situation screening, a patient can enter the imaging chamber 001 by himself, and the imaging process can be completed in the imaging chamber 001 through the medical imaging equipment 000, so that the risk of infection of other operators can be effectively reduced without intervention of other operators.
Optionally, the imaging system may further include: an entrance passage 005 communicating with the first robot gate 001a, an exit passage 006 communicating with the second robot gate 001b, and a sterilizing device 007 located in the imaging chamber 001, the entrance passage 005 and the exit passage 006. The disinfection device 007 may be connected to a control device. The control device 007 is further configured to: after controlling the second automatic door to close, the sterilizing device 007 is controlled to sterilize the imaging chamber 001, the entrance passage 005 and the exit passage 006. In this case, when the imaging system is applied in the scene of epidemic screening, the probability of virus transmission can be reduced as much as possible through the inlet channel 005 and the outlet channel 006. And after each imaging of the user's target site, the imaging chamber 001, the entrance channel 005 and the exit channel 006 are sterilized by the sterilizing device 007, so that the probability of virus transmission can be further reduced.
Alternatively, the imaging pod 001 in the imaging system may comprise a removable pod. When the imaging system is applied to a scene of epidemic situation screening, the imaging cabin 001 can be moved to an area needing epidemic situation screening such as a hospital or a community through the movable cabin body, and after a user in the area enters the imaging cabin 001, the target part of the user is imaged by the medical imaging equipment 000.
Alternatively, the enclosure 001 may be an enclosure having shielding properties. Thus, when a patient uses the medical imaging device in the cabin 001, the medical imaging device only generates radiation in the cabin 001, and the radiation does not leak out of the cabin 001, so that personnel outside the cabin 001 are prevented from being radiated.
In the present application, at least part of the cabin 001 is a transparent part. The transparent part material can be transparent glass made of a material with a ray blocking function, such as lead glass. For example, the transparent portion of the pod 001 may be a window integrated into the pod 001. The transparent glass material containing the metallic lead not only can effectively shield radiation in the cabin, but also can reduce the probability of claustrophobia generated by patients in the cabin in the use process.
