Description
Technical Field
The embodiment of the invention relates to a medical imaging technology, in particular to a method and a device for generating a scanning protocol, an electronic device and a storage medium.
Background
Medical imaging examinations including Magnetic Resonance Imaging (MRI), positron emission tomography (PET-CT), positron emission tomography (PET-MR), etc. are known as fixed workflow types.
Taking MR examination as an example, the method includes combining a scanning protocol in one or more phases according to automatic, manual, breath-hold and other scanning modes to form different workflows, wherein the automatic and manual workflows can set an interval between scanning times when the scanning times are greater than 1, suspend scanning after the last scanning is finished, and automatically start the next scanning after the interval time; when the number of scanning sections is more than 1, the scanning is continuously carried out between the sections without stopping the scanning and playing the voice.
When the scanning section number of the breath-holding workflow is more than 1, the section can be automatically paused in the scanning process, if the scanning is needed to be continued after the pause, the user needs to manually click to continue, the protocol can be continuously scanned, and if voice exists in the scanning interval, the voice can also be played; when the scanning times are more than 1, the interval time can be set between the scanning times, after the previous scanning of the protocol is finished, the scanning is automatically suspended, and after the interval time is counted down, the user clicks to continue the next scanning.
Assuming that the user needs to play a voice after each scan is finished to inform the patient that he can breathe and prepare for the breath hold of the next scan, the user can only select the breath hold workflow, but the breath hold workflow can only set one epoch type, and the user needs to manually click to continue to start the next scan.
Therefore, in the existing workflow types, the phase type set by the user is fixed, some abnormal clinical scenes are difficult to realize, the abnormal clinical scenes need to be realized by scanning of a plurality of protocols, the complexity of user operation is increased, and the abnormal clinical scenes can be finished only by depending on very rich operation experience of an operator.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for generating a scan protocol according to an embodiment of the present invention, where this embodiment is applicable to a case where each section or each scan interval in a scan protocol sets a phase scan with a different period, and the method may be executed by a device for generating a scan protocol, where the device for generating a scan protocol may be implemented by software and/or hardware, and the device for generating a scan protocol may be configured on a computing electronic device, and specifically includes the following steps:
and S110, displaying a scanning parameter interface of the current protocol to be scanned of the scanning object.
For example, the scanning object may be an object to be scanned, such as a human body, an animal, a body part of the human body or the animal, or an area containing a plurality of body parts. The protocol to be currently scanned may be a protocol for scanning the currently scanned object. The scan parameter interface may be an interface for displaying scan parameters, for example, the scan parameter interface may be as shown in fig. 2, and in the interface of fig. 2, scan parameters of a protocol to be scanned currently may be displayed, such as phase direction (phase encoding direction), echo number, repetition Time (TR), echo Time (TE), sampling time (acquisition time, TA), Echo Spacing (ES), inversion Time (TI), layer number, layer thickness, and the like. Thus, the phase setting interface can be obtained based on the scanning parameter interface, so that each phase can be set in the phase setting interface.
Specifically, the scan parameter interface may be obtained in response to an operation of clicking registration information of the scan object by the user, or in response to an operation of clicking a current protocol to be scanned of the scan object by the user, or in response to a user clicking a protocol list corresponding to a plurality of candidate scan protocols under a target scan portion of the scan object.
And S120, responding to a phase setting instruction based on the scanning parameter interface, and displaying a phase setting interface, wherein the phase setting interface comprises a secondary scanning phase setting interface and a section scanning phase setting interface.
For example, the phase setting instruction may be an instruction for setting a phase, and for example, the phase setting instruction may be generated based on an operation for setting a phase, for example, the number of scans in fig. 2 represents the number of times required to perform imaging on a scan object or the number of beds formed by movement of a patient bed, the number of scan nodes in fig. 2 represents the number of phases of movement of a scan object corresponding to each scan or each bed, and different scan instructions may be generated by clicking the a button and/or the B button in fig. 2. The phase setting interface may be an interface that can set a phase, for example, a schematic diagram of the phase setting interface as shown in fig. 3. The phase setting interface includes a sub-scanning phase setting interface and a sectional scanning phase setting interface, for example, fig. 3(a) is the sub-scanning phase setting interface, and fig. 3(b) is the sectional scanning phase setting interface. The sub-scanning period setting interface can set or adjust parameters for all sub-scanning of the current protocol to be scanned, and each scanning can perform different functions on the scanned object, such as: controlling the sickbed to move, and scanning different sub-regions of a scanned object; the section scanning period interface may be a parameter setting or adjusting for all section scanning in each scanning of the current protocol to be scanned, and each scanning may include multiple section scanning.
All the joint scans of any one scan are the scan, referring to the relationship diagram of the joint scan and the sub-scan described in fig. 4, the workflow of three-section and two-time scan is taken as an example in fig. 4, that is, the current protocol to be scanned scans twice in total, the two scans correspond to different functional images, and each scan can be performed in three sections according to the physiological motion cycle of the scanned object. In fig. 4, a is the phase set for each scan, b is the phase set for each section scan, the numbers 1, 2, and 3 indicate the scan of a certain section, and the sum of all the section scans of a certain time is a certain scan. In this embodiment, the first scanning and the second scanning may respectively correspond to different scanning beds, and the medical images corresponding to most of the scanning beds may be obtained by stitching the images obtained under the different scanning beds.
And displaying the phase setting interface in response to the phase setting instruction based on the scanning parameter interface, so that a subsequent user can adjust the phase setting parameters of the secondary scanning and/or the phase setting parameters of the section scanning in the secondary scanning phase setting interface and/or the section scanning phase setting interface which are visual and vivid by developing the secondary scanning phase setting interface and the section scanning phase setting interface.
Optionally, the scan parameter interface includes a call control of the secondary scan phase setting interface and a call control of the secondary scan phase setting interface.
For example, the invoking control of the sub-scanning phase setting interface may be a control for invoking the sub-scanning phase setting interface, for example, a button or a link, etc., such as the invoking control of the a button setting interface for the sub-scanning phase and the invoking control of the B button setting interface for the scan-saving phase in fig. 2. Therefore, the secondary scanning period phase setting interface and/or the section scanning period phase setting interface can be called based on the calling control of the secondary scanning period phase setting interface and/or the calling control of the section scanning period phase setting interface.
Optionally, the displaying the phase setting interface in response to the phase setting instruction based on the scan parameter interface may specifically be: and when any calling control in the scanning parameter interface is detected to be selected, calling a corresponding phase setting interface based on the selected calling control, and displaying.
Illustratively, when it is detected that the calling control of the secondary scanning period phase setting interface and/or the calling control of the section scanning period phase setting interface in the scanning parameter interface are selected, the secondary scanning period phase setting interface and/or the section scanning period phase setting interface are called based on the selected calling control of the secondary scanning period phase setting interface and/or the calling control of the section scanning period phase setting interface, and the secondary scanning period phase setting interface and/or the section scanning period phase setting interface are displayed. For example, when the user clicks the a button in fig. 2, the sub-scan period phase setting interface in fig. 3 is invoked based on the selected a button in fig. 2, and a diagram a in fig. 3 is displayed. The description of the case where the user clicks the B button in fig. 2 and the case where the user clicks the a button in fig. 2 are omitted. Therefore, by developing a secondary scanning phase setting interface and/or a sectional scanning phase setting interface, based on the called and displayed secondary scanning phase setting interface and/or sectional scanning phase setting interface, the phase setting parameters of secondary scanning and/or the phase setting parameters of sectional scanning can be adjusted on the visual and visual secondary scanning phase setting interface and/or sectional scanning phase setting interface.
S130, receiving phase setting parameters of at least one secondary scanning and/or phase setting parameters of at least one section scanning.
For example, the phase setting parameter of the sub-scan may be a parameter for setting the phase of the sub-scan. For example, five types, which may be, but are not limited to, "automatic", "interval", "pause", "0 interval", and "respiration monitoring" as in graph a of fig. 3, may be set before the process of a plurality of scans, indicating operations that need to be performed before the current scan is performed. Wherein: the 'automatic' on the secondary scanning phase interface indicates that the voice is automatically played after the current operation is executed, and the scanning object is matched with the scanning process according to the voice prompt; the "interval" represents the time set by the interval between the number of times of scanning and the operation that has been performed, and the "interval" in the present embodiment represents the time set by the interval after the scanning operation is performed by clicking and then the first scanning is performed; "pause" means to wait for the scan times not to be performed, waiting for further determination by the user; "0 interval" means that the operation to be performed and the operation already performed are continuously performed; "respiration monitoring" means that the physiological monitoring function of the user is started, and the system action between the scanning times and the executed operation is determined according to the result of the physiological monitoring.
The term phase setting parameter of the section scanning may be a parameter that sets the term phases of all the section scanning in each scanning. For example, there may be, but are not limited to, five types "automatic", "interval", "pause", "0 interval", and "respiration monitoring" as in graph b of fig. 3. Before the process of a plurality of section scans of the same scan, operations that need to be performed before the section scan to be currently performed is performed may be set. Wherein: the 'automatic' on the section scanning period phase interface indicates that the voice is automatically played after the current operation is executed, and a scanning object is matched with the scanning process according to the voice prompt; the "interval" represents the time set by the interval between the section to be scanned and the operation that has been executed, and the "interval" in the present embodiment represents the time set by the interval after the scanning operation is executed by clicking and then the first section scanning is executed; "pause" means to wait for the scan times not to be performed, waiting for further determination by the user; "0 interval" means that the section to be scanned is continuously executed with the operation already executed; "respiration monitoring" means that the physiological monitoring function of the user is started, and the system action between the section to be scanned and the operation which is executed is determined according to the result of the physiological monitoring.
In the prior art, the scanning workflow only has three workflow types, namely an automatic workflow, a manual workflow and a breath-hold workflow, but the phase parameter of the secondary scanning and the phase parameter of the section scanning in each workflow are fixed and unchangeable, and after a workflow mode is selected by a user, the phase parameter of the secondary scanning and the phase parameter of the section scanning are fixed and selected by default. For example, when the user selects automatic workflow type to scan, the phase parameter of the secondary scan and the phase setting parameter of the sectional scan in this mode are both automatic or 0 interval, but when the scan of the scan object needs to be performed in a special mode, the phase parameter of the secondary scan and the phase setting parameter of the sectional scan cannot be adjusted, for example, in a breast/pituitary multi-phase scan scene, if there are six sections, the user selects automatic scanning mode, and the user needs to stop scanning after the first section of scan is finished and then continue manually; in the second section to the sixth section, scanning is stopped after scanning is finished, and the next section of scanning is manually started after countdown of a certain time, however, a user cannot set the scene through the existing workflow, and cannot meet the personalized requirements of the user.
However, in the embodiment of the present invention, a mixed workflow type as shown in fig. 2 is developed, and based on the developed secondary scanning phase setting interface and/or the node scanning phase setting interface, at least one externally input secondary scanning phase setting parameter and/or at least one node scanning phase setting parameter may be received on the secondary scanning phase setting interface and/or the node scanning phase setting interface, so that setting and adjustment of the secondary scanning phase parameter and the node scanning phase setting parameter may be implemented according to user requirements, thereby satisfying personalized requirements of users, and implementing an effect of reducing loading of multiple scanning protocols and rapidly completing scanning without adding multiple scanning protocols.
Optionally, the phase setting interface includes a phase parameter input control, or a selection control of each phase parameter.
For example, the phase parameter input control may be a control in which a phase parameter can be input, for example, the "□" button in fig. 3(a) or fig. 3(b), and may be a control in which a specific numerical value is input in the phase parameter input control of "interval" in fig. 3(a) or fig. 3(b) to indicate the time of the interval, for example, the numerical value "2" is input in the phase parameter input control of "interval" to indicate the interval of 2 seconds. Of course, it is also possible to directly click the adjustment indicator behind the "□" button in fig. 3(a) or fig. 3(b) to add a specific numerical value.
The phase parameter selection control may be an "o" button in front of five types of automatic, interval, pause, 0 interval, and respiration monitoring, for example, as in fig. 3(a) or 3(b), indicating that the phase parameter is selected when the control is selected, and indicating that the phase is selected when any one of the o buttons is selected. Therefore, different phase types can be selected subsequently through the phase parameter input control and/or the phase parameter selection control, personalized requirements of users are met, a plurality of scanning protocols do not need to be added, loading of a plurality of scanning protocols is reduced, and scanning is completed quickly.
Optionally, the receiving of the phase setting parameter of at least one secondary scan, and/or the phase setting parameter of at least one section scan may specifically be: collecting phase setting parameters of secondary scanning and/or phase setting parameters of section scanning through a phase parameter input control; or when detecting that the selection control of any phase parameter in the secondary scanning phase setting interface and/or the section scanning phase setting interface is selected, determining the phase parameter corresponding to the selected control as the input phase parameter.
Illustratively, the phase setting parameter of the acquisition sub-scan and/or the phase setting parameter of the section scan may be input through the phase parameter input control, for example, a specific numerical value may be input in the "□" button in fig. 3(a) or fig. 3(b) to indicate the time of the interval. Or, when it is detected that the selection control of any phase parameter in the sub-scanning phase setting interface and/or the segment scanning phase setting interface is selected, determining the phase parameter corresponding to the selected control as the input phase parameter, for example, when an o button in front of any one of the five types of automatic, interval, pause, 0 interval and respiration monitoring shown in fig. 3(a) or fig. 3(b) is selected, indicating that the type phase is selected, determining the selected phase parameter as the input phase parameter. Therefore, the phase parameters can be input through the phase parameter input control and/or the phase parameter selection control, the personalized requirements of users are met, a plurality of scanning protocols do not need to be added, the loading of the plurality of scanning protocols is reduced, and the scanning effect is rapidly completed.
In practical application, it may be exemplified by the two-time three-section workflow in fig. 4, when the user clicks the "select mark" button in front of "2" in the a diagram in fig. 3, it indicates that the user needs to set the phase parameters in the first and second scanning pauses, and when the user clicks the "pause" button in front of this type, it indicates that the first and second scanning pauses, i.e. after the first scanning is completed, the scanning pauses, and then the user manually clicks to continue (not shown in the figure), and then the second scanning is performed. When the user clicks the "select mark" button in front of "3" in the b diagram in fig. 3, it indicates that the user needs to set the phase parameters in the scanning intervals of the second and third sections, and when the user clicks the "o" button in front of the "0 interval" type, it indicates that the scanning is continuously performed without stopping in the scanning intervals of the second and third sections, that is, after the scanning of the second section is completed, the scanning of the third section is directly continued.
When the user clicks the "breath monitoring" button in front of this type in the b diagram of fig. 3, this indicates that the breathing of the scanned subject is to be monitored intermittently between the first and second scans.
Optionally, the phase setting parameters of the section scanning and/or the phase setting parameters of the secondary scanning further include: and voice prompt parameters.
For example, when scanning the abdomen of the scanned subject, taking the user click the "select mark" button in front of "3" in the b diagram in fig. 3 as an example, that is, the user needs to set the phase parameter in the second and third section scanning intervals, when the user selects the "o" button in front of the "respiration monitoring" type, it means that the respiration monitoring scanning is performed in the second and third section scanning intervals, that is, after the second section scanning is completed, the user needs to hold breath for a certain time, and then the third section scanning is performed, but after the second section scanning is completed, for example, a voice prompt of "breathable" can be played, and before the third section scanning is performed, the voice prompt will be automatically played, and the third section scanning will be performed, for example, a voice prompt of "hold breath" can be played, thus, by repeatedly holding breath several times, the whole scan is realized. This allows the user to be clearly aware that the next phase of scanning is about to take place.
It should be noted that, when the user selects the "automatic" phase type, the scanning device will default to select the voice prompt parameters, and during the scanning process, if there is voice, the voice will be automatically played. When the user selects the phase type of "0 interval", the scanning device will default to not select the voice prompt parameter, and will not play voice during the scanning process.
S140, generating the current protocol to be scanned of the scanning object based on the phase setting parameters of the secondary scanning and/or the phase setting parameters of the secondary scanning.

Fig. 5A is a flowchart of a scan protocol generation method according to a second embodiment of the present invention, and the second embodiment of the present invention may be combined with various alternatives in the foregoing embodiments. In this embodiment of the present invention, optionally, after displaying the phase setting interface, the method further includes: and generating a recommended period phase parameter according to the scanning object and the scanning type of the scanning object. After the generating the current protocol to be scanned of the scanned object based on the phase setting parameters of the secondary scan and/or the phase setting parameters of the secondary scan, the method further includes: based on the current protocol to be scanned, scanning the image of the scanning object; and determining phase parameters corresponding to the scanning images, and storing and displaying the scanning images and the corresponding phase parameters in an associated manner.
As shown in fig. 5A, the method of the embodiment of the present invention specifically includes the following steps:
s210, displaying a scanning parameter interface of the current protocol to be scanned of the scanning object.
And S220, responding to a phase setting instruction based on the scanning parameter interface, and displaying a phase setting interface, wherein the phase setting interface comprises a secondary scanning phase setting interface and a section scanning phase setting interface.
And S230, generating a recommended phase parameter according to the scanning object and the scanning type of the scanning object.
Illustratively, the type of scan of the scan object may be the type of scan item to be performed by the scan object, for example, the type of scan may be a breast/pituitary scan, or may also be a breath-hold scan, etc. The recommended phase parameter may be a recommendable phase parameter that is automatically generated by the system according to the scan object and the scan type of the scan object.
In one embodiment, the lung of the scanned object needs to be scanned, the scanned object needs to hold breath during scanning, and the user can select the type of "respiration monitoring" in the sub-scanning period phase setting interface, because the scanned object can be scanned only when the stable respiration of the scanned object is monitored, and when the system monitors that the respiration of the scanned object is not stable and fluctuates, the system can automatically select the type of "pause" in the sub-scanning period phase setting interface by the type of "respiration monitoring" and automatically jumps, and at this time, the scanning stops. In addition, considering that in the actual scanning process, one person can not hold the breath for too long, therefore, when the breathing of the scanned object is monitored to be stable, the scanned object is scanned, at the moment, the system can automatically select the type of interval by the automatic jumping of the type of 'breathing monitoring' in the secondary scanning phase setting interface, the user can set the type of interval in the adjusting mark of the type of interval for 12 seconds, the scanning of the lung of the scanned object is realized by repeatedly holding the breath for several times, the system can also automatically set the voice prompt that the scanned object holds the breath before each section of scanning, and thus, the user is not required to remind the scanned object every time.
In one embodiment, when scanning the lung of the scanned object in the present application, the respiratory state of the scanned object may be detected by the respiratory sensor, the respiratory frequency (duration) of the scanned object is determined, and the recommended phase setting parameter for the secondary scanning and the phase setting parameter for the sectional scanning are given by combining the existing empirical data, and an operator (technician) may directly confirm the recommended phase setting parameter for the secondary scanning and the phase setting parameter for the sectional scanning, thereby improving the quality and efficiency of the scanning. Of course, physiological data related to the respiratory frequency of the scanned object and the like can be acquired during examination or registration before scanning of the scanned object, so as to save the scanning time.
Therefore, the recommended period phase parameters are generated according to the scanning object and the scanning type of the scanning object, so that the scanning time can be saved, the scanning effect can be quickly completed, and the scanning efficiency is improved.
It should be noted that, after the system generates the recommended phase parameter according to the scanning object and the scanning type of the scanning object, if the user determines that the generated recommended phase parameter can be directly used, the step S240 is not required to be executed, and if the user determines that the generated recommended phase parameter cannot be directly used, the phase setting parameter of at least one scan and/or the phase setting parameter of at least one scan is also required to be set, the step S240 is executed. That is, either one or both of step S230 and step S240 may be executed, and the setting may be set by the user according to the requirement, which is not limited herein.
In one embodiment, a historical scan protocol database may be pre-established, the historical scan protocol data includes a plurality of different sets of scan parts and scan protocols of the scan parts, the scan parts may be body parts such as liver, breast, pituitary, brain, etc., the scan protocols include the number of scans, the number of scan nodes, and the operation before each scan operation, which are set for imaging the scan parts, and the system can recognize the commands and determine the phase corresponding to each operation. In this embodiment, the elements in the historical scan protocol database are as shown in FIG. 5B. The scanning part corresponding to the first element is the liver, and the function is the liver multiple breath-holding and multi-period scanning: voice broadcast between system calibration (Adj) and pre-scan (pre), the system can identify this operation in the historical scan protocol database as an "automatic" phase; after the pre-scan and between the arterial scans (a in the figure), a priming operation is performed, which the system can identify as a "pause" phase in the historical scan protocol database; the system may identify this operation in the historical scan protocol database as an "interval" by performing an interval between the arterial scan and the venous scan (V in the figure) for a number of seconds. The scanning part corresponding to the second element is mammary gland or pituitary gland, and the function is mammary gland or pituitary gland multicycle scanning: performing zero interval auto-scan between system calibration and pre-scan, the system can identify the operation in the historical scan protocol database as a "zero interval" phase; after the pre-scan and between body position 1 (post 1 in the figure), the system may identify this operation in the historical scan protocol database as a "pause" phase; performing a 0 interval auto scan between body 1 and body 2 (post 2 in the figure), the system may identify this operation in the historical scan protocol database as a "0 interval". The scanning part corresponding to the third element is the liver, and the function is single breath-holding multi-stage scanning of the liver: voice broadcast between system calibration (Adj) and pre-scan (pre), the system can identify this operation in the historical scan protocol database as an "automatic" phase; after the pre-scan and between body position 1 (post 1 in the figure), the system may identify this operation in the historical scan protocol database as a "pause" phase; for a number of seconds to perform an interval between body position 1 and body position 2 (post 2 in the figure), the system may identify this operation in the historical scan protocol database as an "interval"; performing a 0 interval auto scan between body position 2 and body position 3 (post 3 in the figure), the system may identify this operation in the historical scan protocol database as a "0 interval".
S240, receiving phase setting parameters of at least one secondary scanning and/or phase setting parameters of at least one section scanning.
S250, generating the current protocol to be scanned of the scanning object based on the phase setting parameters of the secondary scanning and/or the phase setting parameters of the secondary scanning.
In one embodiment, the current protocol to be scanned may also be optimized with reference to a historical scan protocol database. The following are exemplary:
firstly, a look-up table related to the radio frequency specific absorption rate is established according to a historical scanning protocol database, the look-up table comprises a plurality of data groups, each data group comprises a priori scanning sequence in the historical scanning protocol database and the radio frequency specific absorption rate corresponding to the priori scanning sequence, and the priori scanning sequence comprises a priori scanning protocol and a priori period phase setting.
And S260, acquiring the radio frequency specific absorption rate corresponding to the current protocol to be scanned through the lookup table.
For example, a priori scanning sequence adapted to the current protocol to be scanned can be obtained through a lookup table, and then the estimated radio frequency specific absorption rate of the current protocol to be scanned is determined.
Further, whether the phase setting of the prior period of the prior scanning sequence is the same as the phase setting of the current protocol to be scanned or not can be determined, and if the phase setting of the prior period of the prior scanning sequence is the same as the phase setting of the current protocol to be scanned, the estimated specific radio frequency absorption rate can be directly used as the specific radio frequency absorption rate of the current protocol to be scanned; if the phase settings of the two phases are different, only calculating the total amount of radio frequency energy absorption of the prior scanning sequence, and determining a scanning time period according to the phase setting of the current protocol to be scanned; and calculating the radio frequency specific absorption rate of the current protocol to be scanned according to the total radio frequency energy absorption amount of the prior scanning sequence and the scanning time interval.
S270, judging whether the specific radio frequency absorption rate of the current protocol to be scanned is within a set threshold range, and executing the step S280 if the conditions are met; and if the condition is not met, generating a feedback command, adjusting the scanning sequence to be executed, and returning to the step S230.
Alternatively, adjusting the current sequence to be scanned may be, for example, changing the amplitude, phase, or flip angle of the radio frequency pulse of one channel or a plurality of channels. Fig. 5C is a schematic diagram of a scanning sequence to be executed and an adjusted current scanning sequence to be executed in an embodiment of the present application, where a first row in fig. 5C represents a sequence schematic diagram of different scanning sections in one scanning, and the sequence schematic diagram corresponds to four phases of a motion state of a detection object, respectively, where: the first phase uses a "protocol 1" Fast Spin Echo (FSE) sequence; the second section phase uses a "protocol 2" FSE sequence; the third phase uses a "protocol 3" spin Echo (EPI) sequence; the fourth nodal phase uses a "protocol 4" gradient echo sequence (GRE), with parameters set to "automatic" between different nodal phases. The system calculates and obtains the radio frequency specific absorption rate of the current protocol to be scanned according to the scanning sequence to be executed and the information of the detected object, and prompts that the radio frequency specific absorption rate of the current protocol to be scanned exceeds a set threshold value. The second row in fig. 5C shows a sequence diagram of a possible adjusted current sequence to be scanned, in which the first and second section phases and the parameter between the second and third section phases are set as "interval". In addition, considering that the rf energy accumulation in the detection object body is easily caused by the presence of a plurality of 180 ° pulses in the FSE sequence, the interval parameter between the first and second section phases in the embodiment of the present application is set to be larger than the interval parameter between the second and third section phases. In fig. 5C, the third row shows another possible sequence diagram of the adjusted current sequence to be scanned, because the first section phase and the second section phase continuously use the FSE to cause the energy overrun, in this embodiment of the present application, the "protocol 2" of the second section phase is changed to the EPI, and the "protocol 4" of the fourth section phase is changed to the FSE. By adjusting the execution time sequence of different protocols, the integrity of functional imaging is ensured under the condition of not increasing the checking time.
S280, based on the current protocol to be scanned, scanning the image of the scanning object; and determining phase parameters corresponding to the scanning images, and storing and displaying the scanning images and the corresponding phase parameters in an associated manner.
For example, after the current protocol to be scanned of the scanned object is determined, the scanned object may be subjected to image scanning based on the current protocol to be scanned to obtain at least one scanned image of the scanned object, the scanned image of each scan in each scan may be reconstructed to obtain the scanned image of the scan, or the scanned image of each scan may be reconstructed to obtain the entire scanned image of the scanned object. The method comprises the steps of determining a secondary scanning period phase parameter and/or a sectional scanning period phase parameter corresponding to a scanned image based on the obtained scanned image, and storing and displaying the scanned image and the corresponding secondary scanning period phase parameter and/or the sectional scanning period phase parameter in a correlation mode, so that the problems that due to the fact that the number of phase types of the secondary scanning period phase parameter and/or the sectional scanning period phase parameter is too large, a user (doctor) needs to manually memorize to enable the set phase parameter of a scanning protocol to correspond to the scanned image, and in an environment with large film reading amount or high possibility of interference, the user (doctor) needs to repeatedly check and determine the scanned image are solved, the user (doctor) can rapidly analyze and diagnose the scanned image, and the analysis and diagnosis efficiency of the scanned image is improved.
Of course, in other embodiments, step S270 may be replaced by determining whether the gradient power of the current protocol to be scanned is within a set threshold range, and if the condition is satisfied, step S280 is executed; if the condition is not satisfied, the scan sequence to be executed is adjusted, and the process returns to step S230. In an embodiment, the system may automatically change the mapping relationship between the logical coordinate system and the physical coordinate system according to the requirement of the current protocol to be scanned for the gradient performance, so as to improve the gradient scanning performance, as shown in the following, the mapping relationship between the logical coordinate system and the physical coordinate system in an embodiment of the present application is:
wherein SS represents a slice selection gradient in a logical coordinate system; PE represents the phase encoding gradient in the logical coordinate system; RO represents the readout frequency gradient in the logical coordinate system; z represents a gradient field of a Z axis in a physical coordinate system, wherein the Z axis is the direction of a main magnetic field and is parallel to the long axis of a detection object; x represents a gradient field of an X-axis in a physical coordinate system, the X-axis being in a left-right direction of the detection object; y denotes a gradient field of a Y-axis in the physical coordinate system, the Y-axis being in the front-rear direction of the detection object. Compared with the prior art that each logical gradient corresponds to a physical gradient singly, the method for establishing the mapping relation between the logical coordinate system and the physical coordinate system can improve the gradient performance by 1.5 times.
In yet another embodiment, the performance requirements for each logical axis of the gradient system may be determined according to the protocol currently being scanned. By changing the mapping relation between the logical coordinate system and the physical coordinate system, the logical axis direction with the highest gradient performance requirement can obtain larger gradient composite components, and the logical axis direction with low gradient performance requirement can properly reduce the composite components.
According to the technical scheme of the embodiment of the invention, the recommended period phase parameter is generated according to the scanning object and the scanning type of the scanning object, so that the scanning time can be saved, the scanning effect can be rapidly completed, and the scanning efficiency is improved. Based on the current protocol to be scanned, scanning the image of the scanning object; the phase parameters corresponding to the scanning images are determined, and the scanning images and the corresponding phase parameters are stored and displayed in an associated mode, so that the problems that due to the fact that the phase types of the scanning phase parameters and/or the section scanning phase parameters are too many, the set phase parameters of a scanning protocol need to be manually memorized by a user (doctor) to correspond to the scanning images, and the user (doctor) needs to repeatedly check and determine in an environment with large film reading amount or easy interference are solved, the user (doctor) can rapidly analyze and diagnose during image reading, and the analysis and diagnosis efficiency of the scanning images is improved.
