Description

Technical Field

[0001] The present application relates to the field of data processing, and in particular, to a method, system, storage medium and computer program product for generating a protocol group for medical scanning. Background Art

[0002] Medical imaging technology is widely used in clinical diagnosis, especially in the field of radiology, to obtain information about the internal structure of the human body through technologies such as CT (Computed Tomography) and PET (Positron Emission Tomography).

[0003] In existing clinical diagnosis, a single CT single-modality scan, a single PET single-modality scan, or a PET and CT combined modality scan can be performed as needed. Regardless of the imaging method, the scanning plan needs to be determined with the help of a medical imaging system before scanning. However, existing medical imaging systems can usually only support single-modality image acquisition and processing, such as only CT or PET scanning, and cannot flexibly switch or combine data acquisition of different modalities in the same system. This limits the flexibility of the system, increases the complexity of operation, and is difficult to meet complex clinical needs. Moreover, current imaging protocols are usually designed for specific parts of the body and lack the ability to automatically generate or adjust protocols based on the characteristics of different parts. In particular, for examinations that need to cover multiple parts, the existing protocol group cannot effectively integrate the specific needs of each part, resulting in uneven imaging quality.

[0004] The content of the background technology description is only for facilitating understanding of the relevant technology in this field and is not regarded as an admission of the prior art. Summary of the invention

[0038] Some preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes and is not intended to limit the scope of protection of the present application.

[0039] In modern medical imaging technology, CT uses X-rays to irradiate the object to be tested. Since different tissues absorb X-rays to different degrees, the X-rays will attenuate to different degrees. The detector is used to capture the attenuation information of the X-rays, and a cross-sectional image is generated after computer processing. The obtained image can reflect the anatomical structure information of the object to be tested. PET is an important molecular imaging technology that can be used for early auxiliary diagnosis of diseases and efficacy evaluation. The basic principle of PET is coincidence detection: a radioactive tracer is injected into the object to be tested, and the radioactive tracer decays in the object to produce positrons. The positrons combine and annihilate with negative electrons in the body, and then a pair of gamma rays with the same energy but opposite flight directions are generated. By detecting a large number of gamma rays and matching the coincidence data from the same annihilation event, an image reflecting the physiological and biochemical changes in the object to be tested is generated through image reconstruction.

[0040] In clinical diagnosis, CT is generally used for imaging of anatomical structures, especially for the diagnosis of tumors, trauma, vascular lesions and infections, etc. PET is used for diagnosis and guidance of treatment of tumors, coronary heart disease and brain diseases, etc. The combination of PET and CT can provide anatomical structure and functional metabolic information at the same time, and can find lesions earlier, more accurately and quickly, but correspondingly, the cost is also higher. That is to say, in clinical diagnosis, a single CT single-modality scan, a single PET single-modality scan, or a PET and CT combined modality scan can be performed as needed, but no matter which imaging method is used, it is necessary to determine the scanning scheme with the help of a medical imaging system before scanning. As described in the previous background technology, the existing medical imaging system cannot meet the needs of higher scanning speed, higher scanning accuracy, faster image reconstruction and lower detection cost in the actual scanning process, and in addition to the shortcomings mentioned in the background technology, the existing protocol group often only contains a set of fixed reconstruction parameters. This single reconstruction parameter setting cannot fully consider the differences between different objects to be tested, which limits the adaptability of the system and the accuracy of auxiliary diagnosis.

[0041] To solve the above problems, the present application provides a method for generating a protocol group for medical scanning. Figure 1 FIG. 1 is a first schematic diagram of a method for generating a protocol group for medical scanning according to an embodiment of the present application. Figure 1 As shown, the method for generating a medical scanning protocol group provided by the present application generally includes: S100: Retrieving a historical protocol group according to a user instruction, wherein the user instruction includes the type of the object to be tested, the part to be scanned, and the scanning device, the historical protocol group includes several historical protocols, and the scanning device includes CT, PET, and PET-CT.

[0042] Among them, the user instruction can be obtained through the user interface.

[0043] Among them, the scanning device prompts the modality of the protocol, including CT modality, PET modality and PET-CT modality.

[0044] In the example of obtaining user instructions through a user interface, the protocol group generation method also includes providing multiple graphical models on the user interface for the user to choose from, so that the user can select a model according to the condition of the body to be tested. The protocol group generation method also includes setting a selection position on each model for the user to select a scanning part on the selected model. In addition, the name of the scanning device is also provided for the user to choose. The three together form the user instruction.

[0045] In one example, the calling of the historical protocol group according to the user instruction means that the system calls the historical protocol group that matches the specific information according to the specific information of the user instruction. For example: in one example, the user instruction includes adult, head, and CT scan, then the historical protocol group called is the historical protocol group related to adult head CT scan; in another example, the user instruction includes adult, head, and PET-CT scan, then the historical protocol group called is the historical protocol group related to adult head PET and CT scan. CT protocols can include positioning image protocols, spiral scan protocols, axial scan protocols, etc., and PET protocols can include static PET protocols, dynamic PET protocols, etc.

[0046] It is foreseeable that there may be multiple historical protocol groups related to the user instruction. Therefore, in one example, Figure 2 As shown, the process of calling the historical protocol group according to the user instruction includes: S110: Match data in the database according to the type of the object to be tested, the part to be scanned, and the scanning device, and retrieve a historical protocol group with a correlation greater than a threshold.

[0047] Furthermore, when displayed to the user, the images are sorted according to the relevance, with the higher the relevance, the higher the position.

[0048] The threshold may be set in advance in the system, and the threshold may be any value between 50% and 70%.

[0049] In one example, in order to reduce the workload of user selection, data matching is performed in the database according to the type of the object to be tested, the part to be scanned, and the scanning device, and a historical protocol group with a correlation greater than a threshold is retrieved, including: According to the type of the object to be tested, the part to be scanned and the scanning device, data matching is performed in the database, and a historical protocol group with the highest correlation is retrieved.

[0050] In one example, if the relevance of all historical protocol groups to the user instruction is less than or equal to a threshold, it means that the historical protocol group retrieval fails.

[0051] In one example, in order to solve the problem of failure in retrieving a historical protocol group, the protocol group generation method further includes: S200: If the historical protocol group fails to be retrieved, the historical protocol is retrieved according to the user instruction.

[0052] It should be noted that the historical protocol group is retrieved first, and the historical protocol is retrieved only when the historical protocol group fails to be retrieved.

[0053] The historical protocol and the historical protocol group are constructed based on previous scan data, and the previous scan data includes the type of the measured body, the scanned part, and the scanning device. It should be noted that the type of the measured body and the type of the body to be measured, the scanned part and the part to be scanned, the former is the data of the human body scanned in the past, and the latter is the data of the human body to be scanned. Specifically, the type of the measured body is the type of the human body scanned in the past, and the scanned part is also the part of the human body scanned in the past, while the type of the body to be measured is the type of the human body to be scanned currently, and the part to be scanned is also the part of the human body to be scanned currently.

[0054] The types of subjects to be tested include adults whose weight is greater than a preset value, adults whose weight is less than or equal to a preset value, teenagers, children and infants, and the user can select any one of them. The preset value can be set based on experience or statistical data. It is understandable that there can be multiple preset values, thereby dividing adults into multiple levels. During PET and PET-CT scanning, body weight is closely related to the amount of radioactive tracer injected.

[0055] The parts to be scanned include the whole body, head, brain, neck, upper abdomen, lower abdomen, spine and chest, and the user can select any one of them.

[0056] In one example, if the historical protocol group fails to be retrieved, the historical protocol is retrieved. Figure 2 , the retrieving the historical protocol according to the user instruction includes: S210: Match data in the database according to the type of the body to be tested, the part to be scanned, and the scanning device, and retrieve all relevant historical protocols.

[0057] Among them, as in the above example, the user instruction includes adult, head, and CT scan, then all historical protocols related to adults, all historical protocols related to the head, and all historical protocols related to CT scan are retrieved.

[0058] Exemplarily, all relevant historical protocols may be displayed to the user in a list format for selection by the user.

[0059] After the user operation is completed, the protocol group generation method further includes: S300: Generate a new protocol group according to the selection or modification of the historical protocol by the user, or according to the modification of the historical protocol in the historical protocol group by the user, and according to the acquisition parameters and reconstruction parameters provided by the user.

[0060] Specifically, Figure 3 As shown, the generating of a new protocol group according to the selection or modification of the historical protocol by the user, or according to the modification of the historical protocol in the historical protocol group by the user, and according to the acquisition parameters and reconstruction parameters provided by the user, includes: S310: Record the deletion of historical protocols in the historical protocol group by the user, the new protocol added by the user, and the acquisition parameters and the reconstruction parameters provided by the user, and integrate the remaining historical protocols, the new protocol, the acquisition parameters and the reconstruction parameters in the historical protocol group to obtain the new protocol group.

[0061] When the historical protocol group is retrieved successfully, if multiple historical protocol groups are provided, first receive the user's selection of the historical protocol group, and then receive the user's modification of the historical protocols in the historical protocol group, for example, delete some protocols, add some protocols, or modify the content of some protocols, and delete some or all of the acquisition parameters or reconstruction parameters attached to the protocols, receive the acquisition parameters and reconstruction parameters newly filled in by the user, or store the acquisition parameters and reconstruction parameters selected by the user, integrate the above information to form a new protocol, and save the new protocol into the database for next use, thereby realizing continuous updating of the database.

[0062] Specifically, see Figure 3 , generating a new protocol group according to the selection or modification of the historical protocol by the user, or according to the modification of the historical protocol in the historical protocol group by the user, and according to the acquisition parameters and reconstruction parameters provided by the user, including: S320: Record the historical protocol selected by the user from the historical protocols, the new protocol obtained by the user based on one or some historical protocols, and the acquisition parameters and the reconstruction parameters provided by the user, and integrate the selected historical protocol, the new protocol, the acquisition parameters and the reconstruction parameters to obtain the new protocol group.

[0063] When the historical protocol group fails to be retrieved, all related historical protocols are provided. First, the historical protocol selected by the user is received, and then the historical protocol modified by the user and the protocol newly added by the user are received. At the same time, since some or all protocols are accompanied by acquisition parameters or reconstruction parameters, the acquisition parameters and reconstruction parameters filled in by the user, or the acquisition parameters and reconstruction parameters selected by the user are received, and the above information is integrated to form a new protocol, and the new protocol is saved in the database for next use, thereby realizing continuous updating of the database.

[0064] Usually when a new protocol group is generated, it is necessary to name the new protocol group so as to distinguish it from other protocol groups in the database. Figure 4 As shown, the protocol group generation method also includes: S301: receiving and verifying the name of a new protocol provided by a user, and generating a name error instruction when the name of the new protocol is repeated with the name of any of the historical protocol groups.

[0065] The name error instruction may be displayed to the user in the form of a pop-up window to prompt the user to modify the name until there is no duplicate name and then save the new protocol name.

[0066] In addition, the acquisition parameters and the reconstruction parameters are mainly used for the parameter description of the underlying hardware device and the interface description of the reconstruction algorithm. The limitations of the current, voltage, etc. supported by the reconstruction algorithm and the underlying hardware device determine the acquisition parameters and reconstruction parameters. There is a situation where the acquisition parameters and reconstruction parameters provided by the user do not match the actual scanning device.

[0067] Among them, there is an interface description of the reconstruction algorithm for the reconstruction parameters, taking PET scanning as an example, including: the selection of reconstruction algorithm, the number of iterations, the image matrix value, the GPU reconstruction value, the count correction value, the attenuation correction value, the scatter correction value, the median filter value, the Gaussian filter algorithm value, etc. Exemplarily, the selection of reconstruction algorithms includes ordered subset iterative reconstruction algorithm (OSEM_PSF), ordered subset iterative reconstruction algorithm with time information (OSEM_TOF) and analytical reconstruction algorithm (FBP). Exemplarily, the image matrix value is, for example, 500*500 or 250*250, indicating the number of pixels of the reconstructed image in the x direction and the y direction. Exemplarily, the GPU reconstruction value is, for example, yes or no, indicating whether the GPU is used for reconstruction, and using the GPU will get the image faster. Exemplarily, the count correction value is, for example, yes or no, indicating whether the activity decay is corrected for the collected projection data. Exemplarily, the attenuation correction value is, for example, yes or no, the purpose of which is to compensate for the count loss caused by the interaction with the medium before the photons reach the detector. Exemplarily, the scatter correction value is, for example, yes or no, and the purpose is to remove the erroneous response lines caused by the change of the original forward direction of the photons due to the interaction with the medium before reaching the detector. Exemplarily, the median filter value is, for example, yes or no, which is a nonlinear smoothing technology that sets the gray value of each pixel point to the median gray value of all pixels in a certain neighborhood window of the point.

[0068] In one example, see Figure 4 , the protocol group generation method further includes: S302: verifying the acquisition parameters and reconstruction parameters provided by the user, and generating an acquisition parameter error instruction or a reconstruction parameter error instruction if the acquisition parameters or the reconstruction parameters are unqualified.

[0069] Exemplarily, all acquisition parameters and all reconstruction parameters cannot be empty, and some parameters need to be qualified. For example, hardware equipment parameters have power range restrictions, the number of beds cannot be negative, and reconstruction algorithm interface parameters have value ranges. For example, the half-width in the Gaussian filter algorithm has a value range of 0~10.

[0070] In an example, there is only one set of acquisition parameters, but there may be multiple sets of reconstruction parameters. The user may generate multiple sets of reconstruction parameters through a new button on the user interface as needed.

[0071] For example, the scout image protocol in CT scanning is relatively special, and there is only one set of acquisition parameters and reconstruction parameters.

[0072] It should be noted that the acquisition parameters shown in the protocol group generation method support modification but not deletion, while the reconstruction parameters support modification, adding one or more groups, and deleting one or more groups. In the case of deletion, it is necessary to ensure that at least one set of reconstruction parameters is retained.

[0073] As mentioned above, the prior art only supports one set of reconstruction parameters, so that the scanning field of view is also single, which will result in that the differences between different objects to be tested cannot be considered during scanning. In the above example of the present application, multiple reconstruction parameters are set. Figure 4 The protocol group generation method provided in this application also includes: S303: Selecting a scanning field of view from a previous database according to the reconstruction parameters, and merging the selected scanning field of view into the new protocol group, so as to generate images of different angles and ranges.

[0074] The method of selecting the scanning field of view according to the reconstruction parameters has many advantages, such as: First, it can adapt to different clinical needs. When the part to be scanned is a small area such as the brain or chest that requires high detail, selecting a smaller scanning field of view according to the reconstruction parameters can improve the spatial resolution of the image, and the resulting image can more clearly display the edges and internal structures of the structure, and a smaller scanning field of view can reduce artifacts caused by movement or breathing, such as reducing image blurring caused by cardiac movement. In addition, when detecting tiny lesions, selecting a smaller scanning field of view through reconstruction parameters can improve the signal-to-noise ratio of the image and help provide low-contrast details; when the part to be scanned is the whole body or bones, a larger anatomical structure is required, and a larger scanning field of view is selected through reconstruction parameters. For example, in a whole-body PET-CT scan, a larger scanning field of view can obtain a large range of images from the head to the knees at one time.

[0075] Second, it can adapt to different application scenarios. When the application scenario requires rapid acquisition of images, the reconstruction parameters can be set to select a smaller scanning field of view to achieve rapid scanning, reduce scanning time, and thus quickly acquire images; when a comprehensive understanding of the object to be tested is required, a larger scanning field of view can be selected by setting the reconstruction parameters.

[0076] The protocol group generation method for medical scanning provided by the present application sets a number of historical protocol groups, and associates the protocol group with the type of the object to be tested, the part to be scanned, and the scanning device. After receiving the user instruction, the historical protocol group is specifically called, and a new protocol group is further generated according to the user operation. The modality of the protocol group matches the scanning device, and supports three modalities of CT, PET, and PET-CT. It also supports customization for different types of objects to be tested and different scanning parts, which is convenient for automatically generating or adjusting the protocol according to the specific part of the object to be tested and the characteristics of the lesion, and is also convenient for efficiently managing different modality protocols in the same system, improving the adaptability and convenience of operation of the system, and the customization capability enhances the pertinence of the protocol and ensures high-quality imaging results. At the same time, each time a new protocol group is generated, the database can be updated. It can be foreseen that when the amount of the database accumulates to a certain extent, it can meet the needs of most scanning scenarios. When facing new scanning tasks, the content that needs to be modified will gradually decrease.

[0077] Corresponding to the above-mentioned protocol group generation method, an embodiment of the present application also provides a medical scanning protocol group generation system. Figure 5 FIG. 1 is a schematic diagram of a system for generating a protocol group for medical scanning according to an embodiment of the present application. Figure 5As shown, the protocol group generation system provided by the present application generally includes: a protocol group management module 510 and a protocol management module 520. The protocol group management module 510 is configured to call a historical protocol group according to a user instruction, wherein the user instruction includes the type of body to be tested, the part to be scanned, and the scanning device, the historical protocol group includes several historical protocols, and the scanning device includes CT, PET, and PET-CT. Among them, the user instruction can be obtained through the user interface. Among them, the scanning device prompts the modality of the protocol, including CT modality, PET modality, and PET-CT modality.

[0078] In the example of obtaining user instructions through a user interface, the protocol group generation method also includes providing multiple graphical models on the user interface for the user to choose from, so that the user can select a model according to the condition of the body to be tested. The protocol group generation method also includes setting a selection position on each model for the user to select a scanning part on the selected model. In addition, the name of the scanning device is also provided for the user to choose. The three together form the user instruction.

[0079] In one example, the calling of the historical protocol group according to the user instruction means that the system calls the historical protocol group that matches the specific information according to the specific information of the user instruction. For example: in one example, the user instruction includes adult, head, and CT scan, then the historical protocol group called is the historical protocol group related to adult head CT scan; in another example, the user instruction includes adult, head, and PET-CT scan, then the historical protocol group called is the historical protocol group related to adult head PET and CT scan. CT protocols can include positioning image protocols, spiral scan protocols, axial scan protocols, etc., and PET protocols can include static PET protocols, dynamic PET protocols, etc.

[0080] In practice, since there are many historical protocol groups in the database, there may be multiple historical protocol groups related to user instructions. Therefore, in one example, the protocol group management module 510 matches data in the database according to the type of body to be tested, the part to be scanned, and the scanning device, and retrieves the historical protocol groups with a correlation greater than a threshold.

[0081] Furthermore, when displayed to the user, the images are sorted according to the relevance, with the higher the relevance, the higher the position.

[0082] The threshold is set in advance in the system, and the threshold can be any value between 50% and 70%.

[0083] In one example, the protocol group management module 510 performs data matching in the database according to the type of the object to be tested, the part to be scanned, and the scanning device, and retrieves a historical protocol group with the highest correlation, thereby reducing the workload of the user.

[0084] In one example, if the correlation between all historical protocol groups and user instructions is less than or equal to a threshold, it means that the historical protocol group retrieval fails. In this case, the protocol management module 520 performs the protocol retrieval work. When the protocol group management module 510 fails to retrieve the historical protocol group, the protocol management module 520 retrieves the historical protocol according to the user instruction.

[0085] The historical protocol and the historical protocol group are constructed based on previous scan data, and the previous scan data includes the type of the measured body, the scanned part, and the scanning device. It should be noted that the type of the measured body and the type of the body to be measured, the scanned part and the part to be scanned, the former is the data of the human body scanned in the past, and the latter is the data of the human body to be scanned. Specifically, the type of the measured body is the type of the human body scanned in the past, and the scanned part is also the part of the human body scanned in the past, while the type of the body to be measured is the type of the human body to be scanned currently, and the part to be scanned is also the part of the human body to be scanned currently.

[0086] Among them, the types of bodies to be tested include adults whose weight is greater than a preset value, adults, teenagers, children and infants whose weight is less than or equal to a preset value, and the user can select any one of them. The above-mentioned adults, teenagers, children and infants can be divided according to age. For details, please refer to the classification standards published by relevant organizations. This is only used as a reference for dividing different types. The preset value can be set according to experience or statistical data. It can be understood that there can be multiple preset values, so as to divide adults into multiple levels. During PET and PET-CT scanning, body weight is closely related to the injection amount of radioactive tracer.

[0087] The parts to be scanned include the whole body, head, brain, neck, upper abdomen, lower abdomen, spine and chest, and the user can select any one of them. It should be understood by those skilled in the art that the parts to be scanned are divided according to the needs of common disease examinations and can be adjusted or changed according to clinical related standards. This is only an example and not a limitation.

[0088] In one example, if the historical protocol group fails to be retrieved, the historical protocol is retrieved. Specifically, the protocol management module 520 performs data matching in the database according to the type of the body to be tested, the part to be scanned, and the scanning device, and retrieves all relevant historical protocols.

[0089] Among them, as in the above example, the user instruction includes adult, head, and CT scan, then all historical protocols related to adults, historical protocols related to the head, and historical protocols related to CT scan are retrieved.

[0090] Exemplarily, all relevant historical protocols may be displayed to the user in a list format for selection by the user.

[0091] After the user operation is completed, the protocol group management module 510 is also configured to generate a new protocol group according to the user's selection or modification of the historical protocol, or according to the user's modification of the historical protocol in the historical protocol group, and according to the acquisition parameters and reconstruction parameters provided by the user.

[0092] Specifically, the protocol group management module 510 records the user's deletion of historical protocols in the historical protocol group, the user's addition of new protocols, and the acquisition parameters and the reconstruction parameters provided by the user, and integrates the remaining historical protocols, the new protocols, the acquisition parameters and the reconstruction parameters in the historical protocol group to obtain the new protocol group.

[0093] When the historical protocol group is retrieved successfully, if multiple historical protocol groups are provided, first receive the user's selection of the historical protocol group, and then receive the user's modification of the historical protocols in the historical protocol group, for example, delete some protocols, add some protocols, or modify the content of some protocols, and delete some or all of the acquisition parameters or reconstruction parameters attached to the protocols, receive the acquisition parameters and reconstruction parameters newly filled in by the user, or store the acquisition parameters and reconstruction parameters selected by the user, integrate the above information to form a new protocol, and save the new protocol into the database for next use, thereby realizing continuous updating of the database.

[0094] Exemplarily, the protocol group management module 510 performs data matching in the database according to the type of body to be tested, the part to be scanned, and the scanning device. If the correlation of all historical protocol groups is less than or equal to the threshold, it is determined that the retrieval of historical protocols has failed. At this time, the protocol management module 520 performs data matching in the database according to the type of body to be tested, the part to be scanned, and the scanning device, and retrieves all relevant historical protocols.

[0095] Specifically, the protocol group management module 510 records the historical protocol selected by the user from the historical protocols, the new protocol obtained by the user based on one or some historical protocols, and the acquisition parameters and the reconstruction parameters provided by the user, and integrates the selected historical protocol, the new protocol, the acquisition parameters and the reconstruction parameters to obtain the new protocol group.

[0096] When the historical protocol group fails to be retrieved, all related historical protocols are provided. First, the historical protocol selected by the user is received, and then the historical protocol modified by the user and the protocol newly added by the user are received. At the same time, since some or all protocols are accompanied by acquisition parameters or reconstruction parameters, the acquisition parameters and reconstruction parameters filled in by the user, or the acquisition parameters and reconstruction parameters selected by the user are received, and the above information is integrated to form a new protocol, and the new protocol is saved in the database for next use, thereby realizing continuous updating of the database.

[0097] Usually when a new protocol group is generated, it is necessary to name the new protocol group so as to distinguish it from other protocol groups in the database. Exemplarily, the protocol group management module 510 is also configured to receive and verify the name of the new protocol provided by the user, and when the name of the new protocol is repeated with the name of any of the historical protocol groups, a name error instruction is generated.

[0098] The name error instruction may be displayed to the user in the form of a pop-up window to prompt the user to modify the name until there is no duplicate name and then save the new protocol name.

[0099] In addition, the acquisition parameters and the reconstruction parameters are mainly configured as parameter descriptions of the underlying hardware devices and interface descriptions of the reconstruction algorithm. The current, voltage, etc. supported by the reconstruction algorithm and the underlying hardware devices determine the values ​​of the acquisition parameters and the reconstruction parameters. There is a situation where the acquisition parameters and the reconstruction parameters provided by the user do not match the actual situation of the scanning device. In one example, the protocol group generation system also includes a parameter library, which is configured to verify the acquisition parameters and reconstruction parameters provided by the user. If the acquisition parameters or the reconstruction parameters are unqualified, an acquisition parameter error instruction or a reconstruction parameter error instruction is generated.

[0100] Exemplarily, all acquisition parameters and all reconstruction parameters cannot be empty, and some parameters need to be qualified, for example, hardware equipment parameters have power range restrictions, the number of beds cannot be negative, and reconstruction algorithm interface parameters have value ranges, etc. For the interface description of the reconstruction algorithm and the value range of the reconstruction parameters, please refer to the relevant description in the protocol group generation method, which will not be repeated here.

[0101] In an example, there is only one set of acquisition parameters, but there may be multiple sets of reconstruction parameters. The user may generate multiple sets of reconstruction parameters through a new button on the interface as needed.

[0102] For example, the scout image protocol in CT scanning is relatively special, and there is only one set of acquisition parameters and reconstruction parameters.

[0103] It should be noted that the acquisition parameters shown in the protocol group generation method support modification but not deletion, while the reconstruction parameters support modification, adding one or more sets of reconstruction parameters, and deleting one or more sets of reconstruction parameters. In the case of deletion, it is necessary to ensure that at least one set of reconstruction parameters is retained.

[0104] Exemplarily, the protocol group management module 510 constructs a historical protocol group according to previous scan data, where the previous scan data includes the measured body type, scanned part, and scanned device.

[0105] Exemplarily, the protocol management module 520 constructs a historical protocol based on previous scan data.

[0106] Exemplarily, the historical protocol group and the historical protocol constitute a database.

[0107] As described above, the prior art only supports one set of reconstruction parameters, so that the scanning field of view is also single, which makes it impossible to consider the differences between different objects to be tested. In the above example of the present application, multiple reconstruction parameters are set. Further, the protocol group management module 510 selects a scanning field of view from the previous database according to the reconstruction parameters, and merges the selected scanning field of view into the new protocol group to generate images of different angles and ranges.

[0108] The medical scanning protocol group generation system provided by the present application has many advantages, such as: First, it can adapt to different clinical needs. When the part to be scanned is a small area such as the brain or chest that requires high detail, selecting a smaller scanning field of view according to the reconstruction parameters can improve the spatial resolution of the image, and the image provided can more clearly show the edges and internal structures of the structure, and a smaller scanning field of view can reduce artifacts caused by movement or breathing, such as reducing image blurring caused by cardiac movement. In addition, when detecting tiny lesions, selecting a smaller scanning field of view through reconstruction parameters can improve the signal-to-noise ratio of the image and help provide low-contrast details; when the part to be scanned is the whole body or bones, a larger anatomical structure is required, and a larger scanning field of view is selected through reconstruction parameters. For example, in a whole-body PET-CT scan, a larger scanning field of view can obtain a large range of images from the head to the knees at one time.

[0109] Second, it can adapt to different application scenarios. When the application scenario requires rapid acquisition of images, the reconstruction parameters can be set to select a smaller scanning field of view to achieve rapid scanning, reduce scanning time, and thus quickly acquire images; when a comprehensive understanding of the object to be tested is required, a larger scanning field of view can be selected by setting the reconstruction parameters.

[0110] The protocol group generation system for medical scanning provided by the present application sets a number of historical protocol groups, and associates the protocol group with the type of the object to be tested, the part to be scanned, and the scanning device. After receiving the user instruction, the historical protocol group is specifically retrieved, and the protocol group is further generated according to the user operation. The protocol group of different modalities can be generated, and the three protocol group modalities of CT, PET, and PET-CT are supported at the same time. It also supports the customization of protocols for different types of objects to be tested and different scanning parts, which is convenient for users to automatically generate or adjust the protocol according to the specific parts of the object to be tested and the characteristics of the lesions, and it is also convenient for users to efficiently manage different modality protocols in the same system, which improves the adaptability and convenience of operation of the system, and the customization capability enhances the pertinence of the protocol and ensures high-quality imaging results. At the same time, each time a new protocol group is generated, the database can be updated. It can be foreseen that when the amount of the database accumulates to a certain extent, it can meet the needs of most scanning scenarios.
