Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an ultrasonic diagnostic apparatus and a method for acquiring a section image.
Background
In the medical technology field, various ultrasonic imaging devices using ultrasonic imaging technology are widely used, and can be used for diagnosing diseases by detecting acoustic differences between different tissues or pathological tissues and normal tissues of a human body to know data and forms of human physiology or tissue structures.
In the process of various ultrasonic examinations using an ultrasonic imaging device, medical staff usually needs to scan a series of standard sections of a part to be examined of a patient as a basis for disease diagnosis. In order to improve the work efficiency of the medical staff and standardize the operation flow of the medical staff, the relevant standard sections are generally organized together in a certain sequence or form through a template protocol, so that part of the work is automatically completed by the system to form an ultrasonic automatic workflow. This makes the daily workflow simple, normalized and intelligent.
Currently, the ultrasound automatic workflow mainly performs the ultrasound examination of each section through the following steps: scanning the part to be detected, freezing the image after scanning a standard section, then carrying out operations such as frame selection, measurement, editing and the like on the frozen image, and finally storing the image.

When the existing ultrasonic automatic workflow is adopted to carry out ultrasonic inspection on each section, only one section image can be obtained in one scanning process, if a plurality of section images of the part to be inspected are to be obtained, the part to be inspected needs to be repeatedly scanned for many times, the inspection process is complex, and the inspection time is long.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. The terms "connected" and "coupled" when used herein, unless otherwise indicated, include both direct and indirect connections (couplings).
In the current ultrasound automatic workflow, after a user scans a standard section, an ultrasound image is actively frozen, then operations such as frame selection, measurement, editing and the like are performed in the frozen ultrasound image, and then after a 'save' key is pressed, the system automatically unfreezes the currently frozen ultrasound image so as to facilitate a doctor to scan the next section.
In practice, however, since some effective slices can be found in the multi-frame images just frozen, the medical staff does not want to unfreeze the images, but rather, they want to use them. Such scenarios are many, for example, when blood volume is estimated, the respiratory end diameter and the respiratory end diameter of inferior vena cava need to be measured to know the change of blood volume with respiration and calculate collapse index; in the ultrasonic examination, the medical staff usually let the patient return the stored picture in coordination with the breathing action. For example, in cardiac examinations, when a medical staff needs to measure the left ventricular cardiac function of a patient, dynamic images of a plurality of cardiac cycles of the patient are usually acquired, and two images, a systolic image and a diastolic image, of the same cardiac cycle are selected for measurement. For example, in obstetrical examination, all the sections of the cranium are usually scanned together, and the left and right femur bones are also scanned in a contrast manner.
In addition, when a medical staff performs an ultrasound examination, a frequent operation is a continuous scan, except that a particular part is limited to a specific acoustic window examination, such as an examination of the heart. In continuous scanning, the operation modes of the ultrasonic probe are generally two types: sliding (scanning position change) operation or swinging (scanning angle change) operation. When a large object under examination is scanned as a whole, the scanning result generally includes standard slices required to be scanned. Therefore, it is possible for the medical staff to obtain a plurality of sectional images requiring image storage through continuous scanning.
However, in some cases, the examination of the medical staff is limited by some conditions, such as unstable emergency patient condition, unsatisfactory obstetrical fetal position, etc., and when the examination conditions are met, the medical staff is required to complete the scanning as many as possible within a short limited time to prevent the conditions from being lost at any time, and then the images are stored uniformly. In the current ultrasonic automatic workflow, even if medical staff obtains a plurality of section images in one scanning, since the ultrasonic diagnostic apparatus cannot know whether the current frozen image contains a plurality of section images required to be stored, the ultrasonic diagnostic apparatus can still automatically unfreeze after the image is stored and enter the next scanning of the section, and the medical staff needs to repeatedly scan the standard section which can not be stored and freeze the stored image again. Therefore, precious scanning time of medical personnel is wasted, and the efficiency of ultrasonic examination is reduced. On the other hand, when scanning conditions are changed, for example, when the fetal position is changed during obstetrical examination, medical staff can hardly scan the previous section image, but the image cannot be stored in time at the moment, and only scanning can be performed again, so that the pregnant woman needs to take a period of time and then resume the examination, the time of ultrasonic examination is prolonged, and unnecessary troubles are brought to the medical staff and patients.
Based on this, the scheme of the invention is provided. In the embodiment of the invention, the ultrasonic diagnostic apparatus judges whether the freezing keeping function is activated or not after the selected section image is stored, keeps the frozen state of the frozen image when the freezing keeping function is activated, and unfreezes the frozen image when the freezing keeping function is not activated or a unfreezing instruction is received.
An embodiment of the present invention provides an ultrasonic diagnostic apparatus, a schematic structural diagram of which is shown in fig. 1, and the ultrasonic diagnostic apparatus includes an ultrasonic probe 10, a host 20, and a human-computer interaction device 30.
In one embodiment, the ultrasonic probe 10 is connected to the host 20, and is configured to transmit an ultrasonic wave to the site to be detected under the control of the host 20, and receive an echo of the ultrasonic wave to obtain an ultrasonic echo signal. The host 20 is configured to generate an ultrasound image according to the ultrasound echo signal in an ultrasound real-time scanning state; freezing the ultrasonic image when the host 20 receives the freezing instruction to obtain a frozen image, receiving an operation instruction for selecting a section image from the frozen image, taking one or more frames of ultrasonic images selected from the frozen image as the selected section image according to the operation instruction, saving the selected section image when the saving instruction is detected, judging whether a freezing keeping function is activated, and keeping the frozen image in a frozen state when the freezing keeping function is activated, wherein the frozen image comprises at least one frame of ultrasonic image; the human-computer interaction device 30 is connected with the host 20 for receiving user input and displaying ultrasound images.
The host 20 may include, among other things, transmit circuitry, a transmit/receive selection switch, receive circuitry, beam-forming circuitry, and a processor. The transmit circuitry may energize the ultrasound probe 10 to transmit ultrasound waves toward the target area. The receiving circuit may receive an ultrasonic echo returned from the target region through the ultrasonic probe 10, thereby obtaining an ultrasonic echo signal or data. The ultrasonic echo signals or data are sent to a processor after being processed by the beam forming circuit. The processor processes the ultrasonic echo signal or data to obtain an ultrasonic image of the part to be detected. The ultrasound images obtained by the processor may be stored in a memory and displayed on an interface of the human interface device 30.
When the freeze-maintaining function is activated, the host 20 is further configured to continue to receive an operation instruction for selecting another slice image from the frozen image after the frozen image is kept in the frozen state, continue to select another frame or frames of ultrasound images from the frozen image according to the operation instruction, obtain another slice image, and save the selected another slice image when the save instruction is detected.
After saving the selected slice image, if the host 20 determines that the freeze-on function is not activated, the frozen state of the frozen image is released.
In one embodiment, the host 20 is further configured to monitor whether a unfreezing command is received in real time, and when a unfreezing command is received, the frozen state of the current frozen image is released.
Based on the ultrasonic diagnostic apparatus shown in fig. 1, an embodiment of the present invention provides a method for acquiring a slice image, and a flowchart thereof refers to fig. 2, where the method for acquiring a slice image may include the following steps:
step 101: the ultrasound image is frozen.
In the ultrasound real-time scanning state, the host 20 monitors a freezing instruction, and freezes the ultrasound image when receiving the freezing instruction to obtain a frozen image, wherein the frozen image comprises at least one frame of ultrasound image.
Step 102: and selecting a section image.
After obtaining the frozen image, the host 20 receives an operation instruction for selecting a sectional image from the frozen image, selects one or more frames of ultrasound images from the frozen image according to the operation instruction, and uses the selected one or more frames of ultrasound images as the selected sectional image.
Step 103: the selected slice image is saved.
The host 20 listens for a save command, and when the save command is detected, saves the selected section image.
Step 104: it is determined whether the keep-freeze function has been activated.
After the host 20 saves the selected slice image, it determines whether the keep-freeze function has been activated. In practical application, a "keep freeze" function key can be set for the ultrasonic diagnostic apparatus, and when the function key is triggered, the ultrasonic diagnostic apparatus starts the keep freeze function. If the host 20 determines that the ultrasonic diagnostic apparatus has activated the freeze-on function, step 105 is executed; if the host 20 determines that the ultrasonic diagnostic apparatus does not activate the freeze-on-hold function, step 106 is executed.
Step 105: the frozen image is kept in the frozen state.
The host 20 holds the frozen state of the frozen image when it is judged that the freeze-on-hold function has been activated by the ultrasonic diagnostic apparatus. At this time, the user can continue to match and store a plurality of section images from the frozen image under the condition of keeping the current ultrasonic image unfrozen, so that a plurality of standard sections can share the same frozen image, thereby reducing unnecessary repeated scanning times and effectively saving the time of ultrasonic inspection.
Step 106: the frozen state of the frozen image is released.
When the ultrasonic diagnostic apparatus is judged not to activate the freeze-on function, the host 20 directly releases the frozen state of the frozen image, that is, operates according to the existing workflow.
In order to more clearly embody the object of the present invention, further illustration is made on the basis of the above-mentioned embodiments.
The examination of the cranium and face of the fetus with the ultrasonic diagnostic apparatus will be described below as an example. Generally, the standard slices for examining the cranium and face of the fetus may include a cerebellum water balance slice, a nasolabial coronal slice, a central sagittal slice of the face, and two orbital slices, and for convenience of description, the three standard slices are exemplified as the nasolabial coronal slice, the central sagittal slice of the face, and the two orbital slices.
The automatic workflow of the ultrasound diagnostic apparatus can perform examinations according to a random protocol or according to a sequential protocol. When the examination is carried out according to the random protocol, the standard tangent plane can be started by the user at random; when the examination is performed according to the sequence protocol, the ultrasonic diagnostic apparatus will sequentially start the standard section according to a predefined sequence, for example, the examination sequence of the standard section predefined by the automatic workflow is: the coronal section of the nasal lip → the median sagittal section of the face → the orbital section of both eyes, the three standard sections are automatically started in sequence according to the sequence during the ultrasonic detection. When the user starts the ultrasonic diagnostic apparatus to perform ultrasonic examination, the user can firstly select to perform examination according to a random protocol or a sequential protocol.
Taking an example of an ultrasound diagnostic apparatus performing an examination according to a random protocol, fig. 3 shows a flowchart of a method for acquiring a slice image in a specific embodiment, where the method for acquiring a slice image may include the following specific steps:
step 201: a real-time scan is initiated.
When the ultrasonic examination of the fetal cranium and face is performed, the user can directly perform scanning without starting the standard section, at this time, the host 20 starts real-time scanning, and the ultrasonic image in the current scanning state can be displayed on the interface of the human-computer interaction device 30 in real time.
Step 202: and judging whether a freezing instruction is received or not.
In the ultrasonic real-time scanning state, the host 20 monitors the freezing instruction in real time. When the host 20 receives the freeze command, step 203 is executed, otherwise, the freeze command continues to be monitored
Step 203: the ultrasound image is frozen.
When the host 20 receives the freezing instruction, the ultrasonic images are frozen to obtain a frozen image, that is, all the ultrasonic images acquired by the ultrasonic diagnostic apparatus in the period from the scanning start to the time when the freezing instruction is received are obtained, wherein the frozen image comprises at least one frame of ultrasonic image.
Step 204: starting the section of the target to be inspected.
After the frozen image is obtained, the host computer 20 can respond to the user to start the operation of the target section to be checked. Specifically, the host 20 receives a selection instruction for selecting a target section to be inspected from preset sections to be inspected, and determines the selected target section to be inspected according to the selection instruction, so as to start the target section to be inspected. The preset section to be inspected is one or more preset sections to be inspected.
For example, after the host 20 obtains the frozen image, the user can select the central sagittal section of the face from three standard sections for examination of the cranium and the face of the fetus by the human-computer interaction device 30, that is, the central sagittal section of the face is used as the section to be examined, and at this time, the host 20 starts the central sagittal section of the face.
Step 205: and selecting a section image.
For example, the host 20 starts the midsagittal section of the face, and the frozen image includes 3 frames of ultrasound images: s1, S2, and S3, when the user views the 3 frames of ultrasound images through the human-computer interaction device 30, if S1 is found to satisfy the requirement of the midsagittal section of the face, S1 can be selected through the human-computer interaction device 30, and S1 is used as the image of the midsagittal section of the face.
Step 206: it is determined whether a save instruction is detected.
The host 20 also determines whether a save command is detected, if so, step 207 is executed, otherwise, it continues to determine whether a save command is detected.
Step 207: the selected slice image is saved.
When the host 20 detects the saving instruction, the section image selected in step 205 is saved, that is, the selected section image is saved as the section image corresponding to the target section to be inspected.
For example, when the user selects S1 as the slice image of the midsagittal slice of the face through the human-computer interaction device 30 and activates the function key of "save image", the host 20 will save S1 as the slice image corresponding to the midsagittal slice of the face according to the operation.
In one embodiment, after the host 20 selects the slice image, the slice information of the target to-be-inspected slice may be added to the selected slice image, and then the slice image is saved. The section information may include at least one of annotation information, postural picture information and measurement information.
Step 208: it is determined whether the keep-freeze function has been activated.
After the host 20 stores the selected section image, it determines whether the keep-freeze function has been activated, and if the keep-freeze function has been activated, that is, the keep-freeze function is started, step 209 is executed; otherwise, step 211 is performed.
Step 209: the frozen image is kept in the frozen state.
When the host 20 determines that the freeze-on-hold function has been activated, the frozen image continues to be held in the frozen state. At this time, the user can continue to perform the frame selection operation from the frozen image through the human-computer interaction device 30, or start the next target section to be checked to continue to perform the frame selection operation. The host 20 continues to receive an operation instruction for selecting another section image from the frozen image, and uses another frame of ultrasound image selected from the frozen image as the selected another section image according to the operation instruction, and saves the selected another section image when the saving instruction is detected.
For example, after host computer 20 saves S1 as a sectional image corresponding to the midsagittal section of the face, and detects that the freeze-on-hold function has been activated, the frozen state of the frozen image is maintained. At this time, if the user needs to examine the coronal section of the nasal lip, the coronal section of the nasal lip can be selected from three standard sections for examining the cranium and face of the fetus by the human-computer interaction device 30, and the host 20 starts the coronal section of the nasal lip to continue responding to the frame selection operation of the user in the frozen image.
Therefore, after a user obtains the frozen image in one scanning, the section images corresponding to the plurality of standard sections can be matched and stored under the condition that the frozen image is not unfrozen, the unnecessary repeated scanning process is avoided, and the time of ultrasonic inspection is saved.
In one embodiment, if host 20 adds slice information to the selected slice image after the selected slice image, host 20 may clear the current slice information of the frozen image before maintaining the frozen state of the frozen image and continuing to respond to the frame selection operation so as not to affect the subsequent frame selection.
Step 210: and judging whether a unfreezing instruction is received or not.
After the frozen image is obtained by the host 20, the host monitors the unfreezing command all the time while responding to the operations of selecting frames, starting a target section to be checked and the like of the user. When judging that the unfreezing instruction is received, executing step 211; otherwise, continuing to monitor the unfreezing instruction. In practical application, a 'unfreezing' function key can be set for the ultrasonic diagnostic apparatus, and when the function key is triggered, the ultrasonic diagnostic apparatus releases the frozen state of the frozen image.
Step 211: the frozen state of the frozen image is released.
The host 20 determines that the freeze-keeping function is not turned on after saving the selected slice image, or releases the frozen state of the frozen image when receiving a thawing command. At this time, the host 20 returns to the real-time scanning state and continues to monitor the freeze command.
When the ultrasonic examination is performed, the user may directly perform the scanning without starting the standard section, or may start a certain standard section to start the scanning, for example, start the nasolabial coronal section to perform the scanning. In the latter case, after the host 20 obtains the frozen image, step 205 may be directly performed to obtain the slice image corresponding to the standard slice in response to the frame selection operation of the user. In an embodiment, after the frozen image is obtained, the user may also perform a frame selection operation in the frozen image to select a slice image, then start the target slice to be inspected, and determine the selected slice image as the slice image corresponding to the target slice to be inspected. That is, the host 20 may respond to an operation or instruction to select a frame after obtaining the frozen image, and may also respond to an operation or instruction to start a target section to be checked.
In another specific embodiment, the ultrasonic diagnostic apparatus may also perform the examination according to a sequence protocol, and unlike the method shown in fig. 3, the host 20 determines the target section to be examined according to a preset scanning sequence of the section to be examined, where the preset scanning sequence of the section to be examined is a preset scanning sequence of one or more sections to be examined. For example, the sections are automatically started according to a predefined standard section sequence of "nasolabial coronal section → facial median sagittal section → orbital sections".
Specifically, the host 20 automatically starts the coronal section of the nose lip to obtain the frozen image, and then responds to the frame selection operation of the user in the frozen image, specifically executing the process from step 205 to step 211. After step 209 is performed, host computer 20 may self-initiate the midsagittal slice of the face, and repeat the previous steps in response to the user selecting a frame in the frozen image. Thus, until the two orbital slices are checked, the user can trigger the 'unfreezing' function key through the human-computer interaction device 30 to remove the frozen state of the frozen image.
In an embodiment, the host 20 may also use a plurality of frames of ultrasound images selected from the frozen images as the selected sectional images according to the operation instruction of the selected sectional images, and then store the selected plurality of frames of ultrasound images in the corresponding target sectional planes to be inspected, respectively.
Based on the method of the embodiment, a 'freeze-hold' function key and a 'unfreeze' function key can be set for the ultrasonic diagnostic apparatus to respectively start the freeze-hold function and the unfreeze image. If the user does not start the freeze-keeping function, the working flow of the ultrasonic diagnostic apparatus is the same as the existing automatic working flow, that is, after the section image is stored each time, the host 20 automatically unfreezes the image, and scans the next target section to be inspected. And if the user starts the freezing keeping function by triggering the freezing keeping function key, the user can match and store the section images respectively corresponding to the plurality of target sections to be checked under the condition of keeping the current frozen image unfrozen, and then actively unfreeze the frozen image by triggering the unfreezing function key to restore the existing automatic workflow. The method enables a user to freely control whether to unfreeze the current image after saving a section image according to the current scanning condition (namely the obtained effective section) when using the automatic workflow.
When the freezing keeping function is started, the section to be inspected of a plurality of targets can share the same section of frozen image, so that unnecessary scanning times are reduced, the time of ultrasonic inspection is effectively saved, a doctor can temporarily determine whether a current multi-frame ultrasonic image needs to be multiplexed with the section to be inspected of the plurality of targets according to the condition of the ultrasonic image obtained by current scanning, a user only needs to trigger a freezing keeping function key before the section image is stored, the freezing keeping function is started, the frozen image is not automatically unfrozen after the section image is stored, the user can continue to select frames from the collected section of ultrasonic image, and the trouble of repeated scanning is avoided.
Based on the same inventive concept, the embodiment of the present invention provides another ultrasound diagnostic apparatus, whose schematic structural diagram can be seen in fig. 1, and the ultrasound diagnostic apparatus also includes an ultrasound probe 10, a host 20 and a human-computer interaction device 30. The ultrasonic probe 10 is connected to the host 20, and is configured to emit an ultrasonic wave to a site to be detected under the control of the host 20, and receive an echo of the ultrasonic wave to obtain an ultrasonic echo signal. The host 20 is configured to generate an ultrasound image according to the ultrasound echo signal in an ultrasound real-time scanning state, freeze the ultrasound image when a freeze instruction is received, obtain a frozen image, receive an operation instruction for selecting a section image from the frozen image, use a frame of ultrasound image selected from the frozen image as a selected section image according to the operation instruction, store the selected section image when a storage instruction is detected, and determine whether a target section to be inspected corresponding to the selected section image is a preset section to be inspected which is kept frozen, if so, keep the frozen image in a frozen state, where the frozen image includes at least one frame of ultrasound image. The human-computer interaction device 30 is connected with the host 20 for receiving user input and displaying ultrasound images.
In a specific embodiment, after saving the selected section image, the host 20 may determine whether the target section to be inspected corresponding to the selected section image includes a preset freezing identifier, and if the target section to be inspected includes the preset freezing identifier, determine that the target section to be inspected is the preset section to be inspected that remains frozen. The preset freezing mark can be a preset mark such as a specific character, a symbol, a figure, a character and the like.
For example, in the ultrasonic examination of the fetal cranium and facial area, a freezing mark is set for the coronal section of the nose lip, the current target section to be examined is the coronal section of the nose lip, and the frozen image obtained by the host 20 includes 3 frames of ultrasonic images: s1, S2 and S3, when the user checks that S2 meets the requirement of the nasolabial coronal section through the human-computer interaction device 30, the user selects S2 and triggers the save key, and the host 20 saves S2. At this time, the host 20 detects that the nasolabial coronal section contains the preset frozen mark, and does not unfreeze the frozen image, and at this time, the user can continue to select frames from the frozen image.
Based on the ultrasonic diagnostic apparatus of the embodiment, the invention provides another method for acquiring a section image, and the flowchart thereof is shown in fig. 4, and the method can include the following steps:
step 301: the ultrasound image is frozen.
In the ultrasound real-time scanning state, the host 20 monitors a freezing instruction, and freezes the ultrasound image when receiving the freezing instruction to obtain a frozen image, wherein the frozen image comprises at least one frame of ultrasound image.
Step 302: and selecting a section image.
After obtaining the frozen image, the host 20 receives an operation instruction for selecting a sectional image from the frozen image, selects one or more frames of ultrasound images from the frozen image according to the operation instruction, and takes the selected ultrasound images as the selected sectional images.
Step 303: the selected slice image is saved.
The host 20 listens for a save command, and when the save command is detected, saves the selected section image.
Step 304: and judging whether the section to be inspected of the target is a preset section to be inspected which is kept frozen.
After the host 20 stores the selected section image, it is determined whether the target section to be inspected corresponding to the selected section image is a preset section to be inspected which is kept frozen. If yes, go to step 305; if not, go to step 306.
Specifically, the host 20 may determine whether the target to-be-inspected section corresponding to the selected section image includes a preset frozen identifier; if the section to be inspected of the target contains a preset freezing mark, the section to be inspected of the target is judged to be a preset section to be inspected which is kept frozen. The preset freezing mark can be a preset mark such as a specific character, a symbol, a figure, a character and the like.
Step 305: the frozen image is kept in the frozen state.
When the host 20 judges that the target section to be inspected corresponding to the selected section image is a preset section to be inspected which is kept frozen, the frozen state of the frozen image is kept. At this time, the user can continue to match and save the next sectional image from the frozen image under the condition of keeping the current ultrasonic image unfrozen, thereby reducing unnecessary repeated scanning times and effectively saving the time of ultrasonic examination.
Step 306: the frozen state of the frozen image is released.
When the host 20 judges that the target section to be inspected corresponding to the selected section image is not the preset section to be inspected which is kept frozen, the frozen state of the frozen image is directly released, namely, the operation is carried out according to the existing workflow.
