[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] The medical image reconstruction method provided in this application can be applied to Figure 1 In the scanning device shown in FIG. 1 , the scanning device may be a server or a terminal, and its internal structure may be as shown in FIG. Figure 1 As shown. The scanning device includes a processor, a memory, a network interface, a display screen and an input device connected through a system bus. Among them, the processor of the scanning device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The network interface of the scanning device is used to communicate with an external terminal through a network connection. When the computer program on the scanning device is executed by the processor, a medical image reconstruction method is implemented. The display screen of the scanning device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the scanning device can be a touch layer covering the display screen, or a button, trackball or touchpad set on the housing of the scanning device, or an external keyboard, touchpad or mouse, etc.

[0056] Those skilled in the art will understand that Figure 1The structure shown in the figure is merely a block diagram of a portion of the structure related to the scheme of the present application, and does not constitute a limitation on the scanning device to which the scheme of the present application is applied. The specific scanning device may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0057] In one embodiment, Figure 2 As shown, a medical image reconstruction method is provided, which is applied to Figure 1 The scanning device in the example is used to illustrate, including the following steps:

[0058] S101, displaying a customized reconstruction parameter card on a display interface of a scanning device; the customized reconstruction parameter card includes reconstruction parameters customized when the scanning device performs image reconstruction.

[0059] The scanning device may be various types of medical scanning devices, such as computed tomography (CT), positron emission tomography (PET), magnetic resonance imaging (MRI) equipment, etc., which are not limited here. The customized reconstruction parameter card includes multiple reconstruction parameters of different types, or multiple groups of reconstruction parameters, each group of reconstruction parameters can be used to reconstruct an image, for example, Figure 3 The customized reconstruction parameter card shown includes 3 groups of reconstruction parameters, each group of reconstruction parameters includes deformation correction, image filtering, K-space filtering, filter type, etc. The customized reconstruction parameter card allows the user to customize the reconstruction parameters, so that the scanning device can reconstruct the image according to the user-defined reconstruction parameters.

[0060] Optionally, medical images are described by taking magnetic resonance images as an example, and the above reconstruction parameters may include, for example, a reconstruction mode, which may be set to a normal mode corresponding to a conventional average processing method and an advanced mode corresponding to an optimized average processing method; the reconstruction parameters may include a reconstruction matrix, specifically a slice matrix used in reconstruction, which may be set to an acquisition matrix, a two-fold acquisition matrix, a 1.5-fold acquisition matrix, etc.; the reconstruction parameters may include, for example, a uniformization correction, which may be set to "none", "advanced" and "B1", where: "advanced" is to correct the uniformity of the image by pre-collecting the sensitivity of the coil; "B1" is a uniformity correction scheme that combines coil sensitivity information with image processing. In other embodiments, the reconstruction parameters may also be a combination of one or more of image filtering, deformation correction, channel merging mode, window level coefficient, filtering, multi-image sequence storage method, etc.

[0061] Specifically, at least one pre-set customized reconstruction parameter card (such as Figure 3 The display interface shown has customized reconstruction parameter card 1 and customized reconstruction parameter card 2), each customized reconstruction parameter card includes many types of reconstruction parameters, and each type of reconstruction parameter can be displayed in the form of a drop-down menu or by checking, which is not limited here. When multiple customized reconstruction parameter cards are displayed on the display interface, the reconstruction parameters contained in each customized reconstruction parameter card can be the same or different. Multiple customized reconstruction parameter cards can display their respective contents on the interface by switching, and the contents contained in multiple customized reconstruction parameter cards can also be displayed on the display interface at the same time, which is not limited here. It should be noted that Figure 3 The display interface shown is only an example of a display method and content included, and does not constitute a limitation on the content and display method included in the customized reconstruction parameter card in this embodiment.

[0062] S102, obtaining a first operation instruction input on the display interface; the first operation instruction is used to determine a target customized reconstruction parameter from customized reconstruction parameters.

[0063] Among them, the target customized reconstruction parameters are user-defined reconstruction parameters, specifically reconstruction parameters selected by the user from among the many reconstruction parameters included in the customized reconstruction parameter card, and reconstruction parameters currently used by the scanning device when performing image reconstruction based on the currently acquired image data.

[0064] Specifically, when the scanning device scans the target object and collects image data according to the scanning result and enters the image reconstruction process, the scanning device can switch to the display interface of the customized reconstruction parameter card (such as Figure 3 The first operation instruction is a display interface on the customized reconstruction parameter card 1 shown in the figure) for the user to perform corresponding parameter selection operations on the display interface and then input the first operation instruction. The user can input the first operation instruction by checking the parameters on the display interface of the customized reconstruction parameter card. Optionally, the user can also input the first operation instruction by clicking on the drop-down menu in the input box. Of course, the user can also input the first operation instruction in other ways, which are not limited here. The first operation instruction includes the identifier of the target customized reconstruction parameter selected by the user during image reconstruction, so that the scanning device can then obtain the corresponding target customized reconstruction parameter according to the identifier of the target customized reconstruction parameter.

[0065] S103, reconstructing and generating a medical image corresponding to the target customized reconstruction parameters according to the target customized reconstruction parameters and the image data collected by the scanning device.

[0066] Specifically, when the scanning device obtains the first operation instruction input by the user, it can parse the first operation instruction, obtain the identifier of the target customized reconstruction parameter, and further obtain the target customized reconstruction parameter in the database through the identifier of the target customized reconstruction parameter, and then reconstruct and generate a medical image corresponding to the target customized reconstruction parameter based on the target customized reconstruction parameter and the acquired image data. For example, Figure 3 As shown, if the reconstruction parameters selected by the user on the customized reconstruction parameter card include deformation correction 1, image filtering 1, K-space filtering 1, and filtering type 1, that is, these four parameters are used as target customized reconstruction parameters, the subsequent scanning device will perform image reconstruction based on the target customized reconstruction parameters and the acquired image data.

[0067] In the medical image reconstruction method provided in the above embodiment, a customized reconstruction parameter card including reconstruction parameters customized when the scanning device performs image reconstruction is displayed on the display interface of the scanning device, and then the scanning device obtains the first operation instruction input on the display interface, and obtains the target customized reconstruction parameters according to the first operation instruction, and reconstructs and generates a medical image corresponding to the target customized reconstruction parameters according to the target customized reconstruction parameters and the collected image data. The above method realizes that when the scanning device selects reconstruction parameters for image reconstruction, it can customize and add multiple customized reconstruction parameter cards, and reconstruct a group of collected image data according to the target reconstruction parameters on different customized reconstruction parameter cards to generate different images. Compared with the method in which the traditional scanning device can only reconstruct images based on a group of collected image data and a corresponding group of reconstruction parameters, the above method can not only save the time of collecting image data and thus improve the efficiency of image reconstruction, but also can timely view the images of the reconstruction function and perform online homologous data comparison and analysis, so as to optimize the reconstruction parameters according to the analysis results.

[0068] In one embodiment, based on the image reconstruction method described in the above embodiment, an image reconstruction method is also provided. Figure 4 As shown, the method includes:

[0069] S201, displaying a general reconstruction parameter card on a display interface; the general reconstruction parameter card includes default reconstruction parameters when a scanning device performs image reconstruction.

[0070] The general reconstruction parameter card includes a group of reconstruction parameters, and the group of reconstruction parameters is the default reconstruction parameters on the scanning device, that is, the reconstruction parameters set by default when the scanning device is started.

[0071] Specifically, the display interface of the scanning device displays a general reconstruction parameter card and at least one customized reconstruction parameter card (such as Figure 5The display interface shown includes a general reconstruction parameter card, a customized reconstruction parameter card 1, and a customized reconstruction parameter card 2. The general reconstruction parameter card includes a set of default reconstruction parameters, while the customized reconstruction parameter card 1 and the customized reconstruction parameter card 2 each include multiple sets of reconstruction parameters. The reconstruction parameters on the customized reconstruction parameter card may be the same as or different from the reconstruction parameters on the general reconstruction parameter card.

[0072] S202: Reconstruct and generate a medical image corresponding to the default reconstruction parameters according to the default reconstruction parameters and the image data collected by the scanning device.

[0073] Specifically, when the scanning device is started, a general reconstruction parameter card is displayed on the display interface of the scanning device. The scanning device can directly reconstruct and generate a medical image corresponding to the default reconstruction parameters based on the reconstruction parameters on the general reconstruction parameter card and the acquired image data. The user can view the default reconstruction parameters set by the scanning device on the display interface of the general reconstruction parameter card. If the user pre-customizes the reconstruction parameters, the user can click on the customized reconstruction parameter card on the display interface of the scanning device to display the interface of the customized reconstruction parameter card on the display interface so that the user can select a corresponding set of reconstruction parameters on the interface. When the scanning device obtains the target customized reconstruction parameters determined by the user through the customized reconstruction parameter card, the scanning device can reconstruct and generate respective images based on a set of acquired image data according to the default reconstruction parameters and the target customized reconstruction parameters.

[0074] Optionally, when a general reconstruction parameter card and a customized reconstruction parameter card are displayed on the scanning device at the same time, the scanning device displays a medical image corresponding to the target customized reconstruction parameters and a medical image corresponding to the default reconstruction parameters on the display interface at the same time.

[0075] Specifically, when displaying medical images corresponding to different reconstruction parameters, the arrangement of medical images on the display interface can be designed according to actual application requirements and is not limited here. When the scanning device displays medical images corresponding to target customized reconstruction parameters and medical images corresponding to default reconstruction parameters on the display interface, the data source can be marked on the respective images or in the area next to the image display position to distinguish the medical images corresponding to different reconstruction parameters, so as to facilitate the later doctors to quickly analyze the characteristics of each reconstruction parameter based on each reconstructed image to optimize the reconstruction parameters.

[0076] For example, Figure 5For example, if the user inputs the first operation instruction on the customized reconstruction parameter card 1, and then determines the target customized reconstruction parameter 1 on the customized reconstruction parameter card 1, and the user also inputs the first operation instruction on the customized reconstruction parameter card 2, and then determines the target customized reconstruction parameter 2 on the customized reconstruction parameter card 2, when the scanning device performs image reconstruction based on a set of acquired image data, it can simultaneously reconstruct and generate the 0# image according to the reconstruction parameters on the general reconstruction parameter card, reconstruct and generate the 1# image according to the target customized reconstruction parameter 1, and reconstruct and generate the 2# image according to the target customized reconstruction parameter 2. In this embodiment, the reconstruction parameters are set to a multi-sequence storage mode, the image data is acquired by multiple scans, and the 0# image is selected to be saved by the number of scans, that is, the result of each scan is saved as a separate image sequence; the 1# image is saved by the number of echoes, that is, the result of each echo is saved as a separate image sequence; the 2# image is saved by the b value, that is, the result of each b value is saved as a separate image sequence. The above-mentioned embodiment allows the user to view different images reconstructed by different reconstruction parameters in a timely manner by simultaneously displaying images reconstructed by multiple reconstruction parameters, and can perform online homologous data comparison and analysis by viewing multiple reconstructed images, and can further determine the reconstruction parameters corresponding to the images that are more in line with the user's image viewing habits.

[0077] In actual applications, when the scanning device generates and displays multiple images based on the default reconstruction parameters and the target customized reconstruction parameters, the scanning device can also optimize the default reconstruction parameters according to the user's comparative analysis results of the multiple images. Therefore, in one embodiment, a method for optimizing reconstruction parameters is also provided, such as Figure 6 As shown, the method includes:

[0078] S301, obtaining a second operation instruction input on the display interface; the second operation instruction is used to optimize default reconstruction parameters.

[0079] Specifically, when the scanning device reconstructs multiple images based on a set of collected image data, default reconstruction parameters, and target customized reconstruction parameters, the user can analyze and compare the multiple images displayed on the display interface, and then input the second operation instruction by checking the image on the display interface according to the analysis and comparison results. Optionally, the user can also input the second operation instruction by editing text in the input box. Of course, the user can also input the second operation instruction in other ways, which are not limited here. The second operation instruction includes an image identifier, and the image identifier corresponds to the reconstruction parameter corresponding to the image, so that the scanning device can then obtain the corresponding reconstruction parameter according to the image identifier to optimize the default reconstruction parameter on the scanning device; optionally, the second operation instruction can also include an identifier of the reconstruction parameter corresponding to the image, so that the scanning device can then obtain the corresponding reconstruction parameter according to the identifier of the reconstruction parameter to optimize the default reconstruction parameter on the scanning device.

[0080] It should be noted that when the user analyzes and compares multiple images, the user can compare them based on the quality of the images to determine an image with good quality / that meets the requirements, and then further select an image with good quality and input a second operation instruction, so that the scanning device can optimize the default reconstruction parameters based on the reconstruction parameters corresponding to the image with good quality. Optionally, when the user analyzes and compares multiple images, the user can also compare them based on actual application requirements to determine an image that meets the user's requirements, for example, determine from multiple images the image that best meets the doctor's reading habits, and then determine the reconstruction parameters that best meet the doctor's reading habits based on the image.

[0081] In one embodiment, the scanning device may pre-establish an image quality assessment model. In an application environment, the image quality assessment model can perform image quality analysis on medical images corresponding to default reconstruction parameters, automatically recommend reconstruction parameters to be added or adjusted based on the analysis results, and guide the user to determine the target customized reconstruction parameters from the customized reconstruction parameters. Figure 6a The figure is a schematic diagram of magnetic resonance images reconstructed using different reconstruction parameters. The left image is obtained by reconstructing the magnetic resonance signal using the first reconstruction parameter, and the right image is obtained by reconstructing the magnetic resonance signal using the second reconstruction parameter. After the two images are processed by the image quality assessment model, it can be determined that the signal-to-noise ratio of the left image is lower than that of the right image. The system automatically determines the second reconstruction parameter as the target customized reconstruction parameter.

[0082] Optionally, in another environment, a plurality of customized reconstruction parameter cards are displayed on the display interface of the scanning device. Based on this application, the present application provides a specific implementation method for obtaining the second operation instruction, such as Figure 7 As shown, the method includes:

[0083] S601, inputting the medical images corresponding to the target customized reconstruction parameters of each customized reconstruction parameter card into a preset image quality assessment model for instruction assessment to obtain assessment results of each medical image.

[0084] Among them, the image quality assessment model can give scores for different indicators such as image resolution, contrast, signal-to-noise ratio, artifact degree, etc. The image quality assessment model can be a convolutional neural network model or other machine learning network model, which can be pre-trained by the scanning device according to the indicator type and sample data.

[0085] Specifically, based on the operation of the aforementioned embodiment, after the scanning device reconstructs and generates different medical images corresponding to different target customized reconstruction parameters, it can also input the different images corresponding to the different target customized parameters into a preset image quality assessment model to obtain the scoring results corresponding to the different medical images. Afterwards, the scanning device can select the medical images with excellent quality or meeting the score requirements as the target optimized medical images based on the scoring results of each medical image, and then determine the target customized reconstruction parameters corresponding to the target optimized medical images as the reconstruction parameters referenced by the scanning device when optimizing the default reconstruction parameters.

[0086] S602: Display the evaluation results of each medical image on a display interface.

[0087] When the scanning device obtains the evaluation results of each medical image on the display interface based on the image quality assessment model, the evaluation results can be further displayed on the display interface. For example, if the evaluation result is the quality score of each medical image, the corresponding score can be displayed in or near the area where each medical image is displayed, so that the user can distinguish the quality of each medical image through the quantified score on the display interface.

[0088] S603: Acquire a second operation instruction input by the user on the display interface according to each evaluation result.

[0089] After the user views the evaluation results of each medical image on the display interface, the user can know the quality of each medical image. Based on this, the user can select a medical image that meets the requirements or has good quality, perform a selection operation, and thus generate a second operation instruction. This embodiment provides a method for automatically evaluating the quality of each medical image, so that the user can refer to the quantitative scoring results on the basis of intuitively observing the quality of each medical image, and finally input the second operation instruction to determine the optimal target customized reconstruction parameters, so that the default reconstruction parameters can be optimized based on the optimal target customized reconstruction parameters to achieve the best optimization effect.

[0090] S302: Obtain new default reconstruction parameters from a database according to a second operation instruction.

[0091] Specifically, when the scanning device obtains a second operation instruction input by the user, the scanning device can further parse the second operation instruction and obtain the image identification or the reconstruction parameter identification therefrom, and then obtain the reconstruction parameters corresponding to the identification from the database according to the image identification as new default reconstruction parameters, or directly obtain the corresponding reconstruction parameters from the database according to the reconstruction parameter identification as new default reconstruction parameters.

[0092] S303: Modify the default reconstruction parameters on the general reconstruction parameter card according to the new default reconstruction parameters.

[0093] When the scanning device obtains the default reconstruction parameters, the default reconstruction parameters can be used to replace the default reconstruction parameters on the general reconstruction parameter card on the original scanning device, or the default reconstruction parameters on the general reconstruction parameter card on the original scanning device can be modified according to the default reconstruction parameters.

[0094] The above method realizes re-updating the default reconstruction parameters according to the user's needs through the interaction between the scanning device and the user, or optimizing the default reconstruction parameters using the optimal reconstructed image, so that when the scanning device enables the reconstruction of the image next time, it can quickly reconstruct an image that meets the user's needs or an image of high quality based on the default reconstruction parameters, saving the user's time in repeatedly selecting reconstruction parameters and comparing image quality, and improving the efficiency of image reconstruction.

[0095] In actual applications, when a plurality of customized reconstruction parameter cards are displayed on the display interface of the scanning device, it indicates that the user has selected a plurality of different sets of reconstruction parameters to reconstruct and generate an image. In this application scenario, the target customized reconstruction parameters of the plurality of customized reconstruction parameter cards may be different, or may be partially or completely the same. In this case, before executing the above S103, the scanning device may select the reconstruction parameter card of the plurality of customized reconstruction parameter cards. Figure 8 As shown, the following steps are also performed:

[0096] S401, determining whether target customized reconstruction parameters on a plurality of customized reconstruction parameter cards are partially or completely the same, if they are partially or completely the same, executing step S402, if they are completely different, executing step S403.

[0097] When the scanning device reconstructs and generates corresponding images based on the target customized reconstruction parameters on multiple customized reconstruction parameter cards, it is necessary to first determine whether the target customized reconstruction parameters on the multiple customized reconstruction parameter cards are partially or completely the same. If they are the same, it means that the reconstruction parameters selected by the user on the multiple customized reconstruction parameter cards are partially or completely repeated. At this time, the scanning device can reconstruct and generate an image based on the target customized reconstruction parameters on one of the customized reconstruction parameter cards, without wasting resources to generate multiple identical images. If they are not the same, the scanning device immediately reconstructs and generates multiple images based on the target customized reconstruction parameters on different customized reconstruction parameter cards.

[0098] S402, displaying a prompt interface, acquiring a third operation instruction input by the user on the prompt interface, and determining whether to continue generating a medical image corresponding to each target customized parameter according to the third operation instruction.

[0099] The present embodiment relates to an application scenario in which target customized reconstruction parameters on multiple customized reconstruction parameter cards are partially or completely identical. In this scenario, the scanning device directly displays or pops up a prompt interface on the display interface, which includes prompt information to inform the user that there are repeated partial or complete reconstruction parameters, and determines whether to continue to generate medical images corresponding to each target customized parameter through the user's confirmation operation. When the user enters a third operation instruction on the prompt interface to determine to continue generating the image, the scanning device can reconstruct the medical image corresponding to the target customized reconstruction parameters based on the target customized reconstruction parameters on one of the customized reconstruction parameter cards and the image data collected by the scanning device after obtaining the third operation instruction entered by the user on the prompt interface; when the user enters the third operation instruction on the prompt interface to determine not to continue generating the image, the user can re-select new target customized reconstruction parameters on the customized reconstruction parameter card to distinguish the target customized reconstruction parameters on other customized reconstruction parameter cards, thereby generating different reconstructed images.

[0100] S403 , reconstructing and generating medical images corresponding to the target customized reconstruction parameters according to the target customized reconstruction parameters on the customized reconstruction parameter cards and the image data collected by the scanning device.

[0101] This embodiment involves an application scenario where the target customized reconstruction parameters on multiple customized reconstruction parameter cards are completely different. In this scenario, the scanning device directly reconstructs and generates medical images corresponding to each target customized reconstruction parameter based on the target customized reconstruction parameters on each customized reconstruction parameter card and the image data collected by the scanning device. The above method can reduce the waste of resources of the scanning device by setting a prompt interface to remind the user to avoid repeated setting of reconstruction parameters.

[0102] Based on the above embodiment, when the target customized reconstruction parameters on multiple customized reconstruction parameter cards are exactly the same, the present application also provides specific operations of the scanning device in this scenario, such as Fig. 9 As shown, the operation includes:

[0103] S501 : arbitrarily selecting a target customized reconstruction parameter on a customized reconstruction parameter card from a plurality of customized reconstruction parameter cards as a current target customized reconstruction parameter.

[0104] Specifically, because the target customized reconstruction parameters determined by the user on multiple customized reconstruction parameter cards are the same, when reconstructing the medical images corresponding to the target customized reconstruction parameters in the later stage, the scanning device can arbitrarily select the target customized reconstruction parameters on one customized reconstruction parameter card from the multiple customized reconstruction parameter cards as the current target customized reconstruction parameters for image reconstruction, that is, the target customized reconstruction parameters on multiple customized reconstruction cards correspond to the same image.

[0105] S502: Reconstruct and generate a medical image corresponding to the current target customized reconstruction parameters according to the current target customized reconstruction parameters and the image data collected by the scanning device.

[0106] The method described in this step is the same as the method described in the aforementioned step S103. Please refer to the aforementioned description for the specific content, which will not be repeated here.

[0107] In actual applications, there is also an application scenario, that is, because a set of completed scanning parameters can include multi-dimensional data, different reconstruction parameters can be applied to data of different dimensions at the same time, and optimized accordingly according to different scenarios. For example, in dimension T1, different reconstruction parameters should all be reconstructed, and some reconstruction parameters in dimension Bl map (mapping map) may not be operated as needed.

[0108] Optionally, the image data acquisition process collected by the scanning device is: using a gradient echo sequence to excite the scanning object, and using a multi-channel receiving coil to collect signals of multiple echoes, wherein each echo corresponds to a different echo time (echotime, TE), and the TE difference between two adjacent echoes is the relaxation interval time ΔTE. Each echo contains multi-channel signals, and the signals corresponding to different channels belonging to the same echo have the same TE. The reconstruction parameters select the reconstruction parameters corresponding to four different functional images of T2*, T1 and apparent diffusion coefficient (ADC).

[0109] In one embodiment, the T2* functional image can be obtained according to the following relationship (1):

[0110]

[0111] in, represents the transverse relaxation time; γ represents the pixel coordinate; ΔTE represents the relaxation interval time; ΔS(r, ΔTE) represents the signal change corresponding to the echo time.

[0112] In one embodiment, the T1 functional image can be obtained according to the following equation (2):

[0113] T1(r)=-ΔTI / In(ΔS(r,ΔTI)) (2);

[0114] Wherein, γ represents the pixel coordinate; T1(r) represents the longitudinal relaxation time; ΔTI represents the inversion time (TI) interval between adjacent echoes; and ΔS(r, ΔTI) represents the signal change associated with ΔTI.

[0115] In one embodiment, the ADC functional image can be obtained according to the following relationship (3):

[0116] ADC(r)=-Δb / In(ΔS(r,Δb)) (3);

[0117] Among them, ADC(r) represents the diffusion coefficient; Δb represents the b-value difference between adjacent echoes; γ represents the pixel coordinates; ΔS(r, Δb) represents the signal change associated with Δb. Therefore, the reconstruction parameters corresponding to the T2* functional image include TE, channel parameters / number of channels of the receiving coil, and number of echoes / number of echoes. The reconstruction parameters corresponding to the T1 functional image include channel parameters, number of echoes, and inversion time (TI). The reconstruction parameters corresponding to the ADC functional image include channel parameters, number of echoes, and b-value.

[0118] Based on the application and the method described in the above embodiments, the present application also provides a prompt method, which specifically includes: determining whether there are inapplicable target customized reconstruction parameters in the target customized reconstruction parameters, and if so, displaying a prompt message on the display interface; the prompt message is used to indicate to the user the inapplicable target customized parameters.

[0119] Among them, the inapplicable target customized reconstruction parameters are reconstruction parameters that are not operated when reconstructing an image of a certain dimension. Specifically, when the user enters the first operation instruction on the customized reconstruction parameter card and determines the target customized reconstruction parameters, the scanning device will first determine whether there are inoperable target customized reconstruction parameters in the target customized reconstruction parameters for the dimension of the image to be reconstructed. If so, a prompt message will be displayed or popped up on the display interface to inform the user which parameters are inapplicable target customized parameters, so that the user will not perform the selection operation when selecting reconstruction parameters next time, or the user can obtain images with the best image quality and the most consistent with the doctor's reading habits.

[0120] It should be understood that although Figure 2-9 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-9 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
