[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] Currently, when determining the cross-sectional image of an MRI scan, doctors directly scan to obtain a two-dimensional cross-sectional image of the patient. If the cross-sectional image does not meet the requirements, the scanning parameters are manually adjusted to re-obtain the two-dimensional cross-sectional image until the requirements are met. However, manual positioning results in arbitrary cross-sectional views, which cannot guarantee consistency between cross-sectional images obtained from multiple examinations. Moreover, doctors face a large number of patients to scan daily, and often work shifts in the hospital. Different doctors have different positioning habits, making the process cumbersome when the same patient comes for follow-up examinations. It is also difficult to maintain precise consistency with the previous patient's positioning, which is not conducive to patient follow-up and monitoring of the patient's condition progression. Therefore, this application proposes an MRI scanning method, apparatus, computer equipment, and storage medium that can solve the above-mentioned technical problems.

[0057] The magnetic resonance scanning method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown includes a computer device, which may be a server, and its internal structure diagram may be as follows. Figure 1As shown, this computer device includes a processor, memory, input / output interfaces (I / O), and a communication interface. The processor, memory, and I / O interfaces are connected via a system bus, and the communication interface is also connected to the system bus via the I / O interfaces. The processor provides computational and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system, computer programs, and a database. The internal memory provides the environment for the operation of the operating system and computer programs stored in the non-volatile storage media. The database stores image processing-related data. The I / O interfaces are used for exchanging information between the processor and external devices. The communication interface is used for communicating with external terminals via a network. When the computer program is executed by the processor, it implements a magnetic resonance scanning method. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0058] Those skilled in the art will understand that Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0059] In one exemplary embodiment, such as Figure 2 As shown, a magnetic resonance scanning method is provided, which can be applied to... Figure 1 The following explanation uses computer equipment as an example, including the following steps S201 to S204. Wherein:

[0060] S201, Obtain the initial pre-scanned medical image of the object to be scanned.

[0061] The initial pre-scan medical images can be MRI images, computed tomography images, images combining positron emission tomography and MRI images, or sagittal images, tubular images, cross-sectional images, etc., obtained based on MRI images, etc.

[0062] In this embodiment, taking nuclear magnetic resonance (NMR) images as an example, the NMR images can be sent to a computer device after the NMR device scans the object. Alternatively, the computer device can store the NMR images and retrieve them from the storage medium upon receiving a user's retrieval command.

[0063] S202, The marker information in the initial pre-scanned medical image is localized to obtain the target marker information.

[0064] The target marking information varies depending on the scanning site. For example, the target marking information for the head may be the corpus callosum, the raphe cerebral region, etc.; the target marking information for the abdomen may be the umbilicus, the upper edge of the pubic symphysis, etc. Optionally, there may be one or more target marking information.

[0065] In the embodiments of this application, the identification of various marker information of different scanning sites can be based on medical knowledge. For example, if the scanning site is the head, the midline of the brain is located first. If the midline of the brain can be identified and is clearly visible, the midline of the brain is used as the target marker information. If the midline of the brain cannot be identified, the corpus callosum is further located. If the corpus callosum can be identified, the corpus callosum is used as the target marker information.

[0066] In another possible implementation, all the marking information of the scanned area can be identified and processed. If the identified marking information meets the quality requirements, then the identified marking information can be used as the target marking information.

[0067] S203, Perform sectional processing on the initial pre-scanned medical image based on the target marking information to obtain initial sectional positioning information.

[0068] The initial cross-section positioning information can include scanning parameters, cutting point positions, and cutting layer positions.

[0069] It should be noted that the target marking information is used to locate the scanned area of ​​the object. It can be a target marking point or a target marking line. For example, the target marking information mentioned above is the raphe in the brain.

[0070] In this embodiment, due to the different target marking information, the methods used to perform cross-sectional processing on the initial pre-scanned medical image based on the target marking information are different.

[0071] Therefore, when the target label information includes a label information, the pre-scanned medical image can be sliced ​​based on the position information and orientation information of the target label information to obtain the initial slice positioning information.

[0072] When the target label information includes multiple label information, the initial pre-scanned medical image is directly sliced ​​based on the position information of the multiple target label information to obtain the initial slice positioning information. In one possible implementation, when the target label information includes multiple label information, the orientation information can also be determined based on the position information of the multiple target label information. Based on the orientation information and the position information, the initial pre-scanned medical image is sliced ​​to obtain the initial slice positioning information.

[0073] S204, Control the scanning device to scan the object based on the initial section positioning information to obtain the initial magnetic resonance image.

[0074] In this embodiment, based on the initial cross-sectional positioning information, the computer device controls the scanning device to scan the object and obtain an initial magnetic resonance image.

[0075] In the aforementioned magnetic resonance imaging (MRI) scanning method, an initial pre-scan medical image of the object to be scanned is acquired. The marker information in the initial pre-scan medical image is then localized to obtain target marker information. Based on the target marker information, the initial pre-scan medical image is cross-sectionalized to obtain initial cross-sectional localization information. The scanning device is then controlled to scan the object based on the initial cross-sectional localization information to obtain an initial MRI image. In this embodiment, the target marker information is obtained by localizing the marker information in the initial pre-scan medical image. Further cross-sectional processing of the initial pre-scan medical image based on the target marker information yields initial cross-sectional localization information. The scanning device can then scan the object based on this initial cross-sectional localization information to obtain an initial MRI image, avoiding the problem of inaccurate cross-sections caused by doctors directly scanning and acquiring MRI images. Moreover, the target marker information can cover the entire scanning cycle of the object, improving the accuracy of the MRI image while effectively reducing scanning time.

[0076] In one embodiment, the initial pre-scanned medical image is sliced ​​based on target marker information to obtain initial slice localization information, which may include the following two methods:

[0077] The first method: When the target marking information includes a marker, the initial pre-scanned medical image is sliced ​​based on the position and orientation information of the target marker to obtain the initial slice positioning information.

[0078] In this embodiment, assuming the target marker information is a straight line s1 and the direction information of the target marker information is s2, their cross product s1×s2 is directly used as the normal vector to segment the initial pre-scanned medical image and obtain the initial cross-section positioning information.

[0079] The second method: When the target marker information includes multiple marker information, the initial pre-scanned medical image is sliced ​​according to the position information of the multiple target marker information to obtain the initial slice positioning information.

[0080] In this embodiment, assuming the target marker information is P1(x1, y1, z1), P2(x2, y2, z2), and P3(x3, y3, z3), the normal vector of the plane can be obtained by calculating the cross product of two vectors. Specifically, vector AB = P2 - P1 = (x2 - x1, y2 - y1, z2 - z1), and vector AC = P3 - P1 = (x3 - x1, y3 - y1, z3 - z1). Then, the cross product of these two vectors is calculated to obtain the normal vector N = [AB] × [AC]. The initial pre-scanned medical image is then segmented based on the point normal equation to obtain the initial slice localization information.

[0081] In one possible implementation, assuming the target label information consists of two lines s3 and s4 that intersect, their cross product s3×s4 can be directly used as the normal vector to segment the initial pre-scanned medical image and obtain the initial section localization information.

[0082] In one possible implementation, assuming the target marking information consists of two lines, s3 and s4, and the two lines are parallel, the direction vector of one of the lines is selected as the normal vector, and the initial cross-sectional positioning information that can contain the two lines is segmented from the initial pre-scanned medical image.

[0083] In this embodiment, the initial pre-scanned medical image is processed by cross-sectioning based on the target marking information to obtain initial cross-section positioning information, providing users with multiple ways to determine the initial cross-section positioning information and improving the flexibility of obtaining the initial cross-section positioning information.

[0084] Figure 3 This is a flowchart illustrating a method for determining target marker information in one embodiment, such as... Figure 3 As shown, it includes the following steps:

[0085] S301, The marker information in the initial pre-scanned medical image is processed to obtain the positioning result of the marker information.

[0086] The tag information can be one or multiple.

[0087] In this embodiment, combined with Figure 4 As shown, the initial pre-scan medical image of the brain of the scanned object is obtained by performing the first scan of the coronal plane. Using the ridge of the brain as the marker information, the initial pre-scan medical image is input into the pre-trained target localization model to obtain the localization result of the ridge of the brain.

[0088] In one possible implementation, an image localization algorithm can be used to extract feature information from the initial pre-scanned medical image, perform recognition and localization processing on the feature information, and obtain the localization result of the raphe in the brain.

[0089] S302, if the positioning result of the marker information meets the preset quality requirements, the marker information is used as the target marker information.

[0090] In this embodiment, if the positioning result of the marker information meets the preset quality requirements, that is, the marker information exists and is clearly visible, or the quality of the marker information is greater than the preset quality threshold, then the marker information is used as the target marker information.

[0091] In one possible implementation, if there are multiple markers, the markers are located. If only a portion of the markers meet the preset quality requirements, then the portion of the markers that meet the preset quality requirements is taken as the target marker.

[0092] S303, if the positioning result of the marker information does not meet the preset quality requirements, perform positioning processing on the new marker information in the initial pre-scanned medical image to obtain the positioning result of the new marker information.

[0093] If the marking information is abnormal, and / or the image quality of the marking information is less than a preset quality threshold, then the marking information is determined to not meet the preset quality requirements.

[0094] In this embodiment, if the positioning results of the aforementioned first type of marker information do not meet the preset quality requirements—for example, when locating the head in the midsagittal plane, the cerebral suture is selected as the first type of marker information—but when a head lesion causes damage to the cerebral suture structure, new marker information needs to be located. For example, the midline of the skull contour can be used as the marker information, and the midline of the skull contour can be located to obtain the positioning result. Alternatively, when locating the pelvic coronal plane, the pubic symphysis is selected as the first type of marker information. When the pubic symphysis is diseased or unclear, the bilateral femoral heads can be selected as new marker information, and the bilateral femoral heads can be located to obtain the positioning result. The new marker information is also pre-stored in the computer device.

[0095] S304, if the positioning result of the new marker information meets the preset quality requirements, the new marker information shall be used as the target marker information.

[0096] In this embodiment, if the positioning result of the new marker information meets the preset quality requirements, the new marker information is used as the target marker information, and the target marker information used in this scan is recorded in the initial pre-scan medical image of this scan. When the scanned object is scanned again, the target marker information used in the previous scan can be obtained.

[0097] Optionally, if the positioning result of the new marker information does not meet the preset quality requirements, the new marker information can be acquired again until the positioning result of the new marker information meets the preset quality requirements.

[0098] The target marker information is used to perform sectional processing on the current pre-scan medical image to obtain sectional positioning information. The target magnetic resonance image obtained by scanning based on the sectional positioning information is then accurately placed in the scanning frame (i.e., the automatic positioning result of the output interface).

[0099] In this embodiment, the marker information in the initial pre-scan medical image is localized to obtain the localization result of the marker information. If the localization result of the marker information meets the preset quality requirements, the marker information is used as the target marker information. If the localization result of the marker information does not meet the preset quality requirements, the new marker information in the initial pre-scan medical image is localized to obtain the localization result of the new marker information. If the localization result of the new marker information meets the preset quality requirements, the new marker information is used as the target marker information. After subsequent scanning of the object, the pre-scan medical image obtained from each scan can be processed based on the target marker information to obtain the slice localization information, thereby ensuring high consistency of the slice of the target magnetic resonance image obtained in multiple examinations. This standardized and accurate slice localization provides great convenience for patient examination and follow-up examination.

[0100] In one embodiment, the magnetic resonance scanning method further includes: acquiring a current pre-scanned medical image of the object to be scanned; performing cross-sectional processing on the current pre-scanned medical image based on target marker information to obtain current cross-sectional positioning information; and controlling the scanning device to scan the object based on the current cross-sectional positioning information to obtain a current magnetic resonance image.

[0101] The target labeling information is obtained by locating and labeling the initial pre-scanned medical image obtained from the first scan of the scanned object. The initial pre-scanned medical image and the current pre-scanned medical image are images of the same modality, that is, the initial pre-scanned medical image is an MRI image, and the current pre-scanned medical image is also an MRI image. The obtained target labeling information is stored in a dedicated database corresponding to the scanned object. For example, it can be stored in the folder corresponding to the scanned object, in the cloud database of the scanned object, or labeled on the initial pre-scanned medical image.

[0102] In this embodiment, the object to be scanned can be pre-scanned to obtain a current pre-scanned medical image. Target marker information can be obtained from the database. The target marker information can be used to perform cross-sectional processing on the current pre-scanned medical image to obtain current cross-sectional positioning information. Based on the current cross-sectional positioning information, the scanning device can be controlled to scan the object to obtain a current magnetic resonance image. The cross-section of the current magnetic resonance image is consistent with the cross-section of the initial magnetic resonance image.

[0103] In this embodiment, the current pre-scan medical image of the object to be scanned is obtained; the current pre-scan medical image is processed by cross-sectioning according to the target marker information to obtain the current cross-section positioning information; the scanning device is controlled to scan the object based on the current cross-section positioning information to obtain the current magnetic resonance image. Since the current cross-section positioning information is obtained by cross-sectioning the current pre-scan medical image based on the target marker information determined for the first time, the cross-section of the current magnetic resonance image obtained by each scan based on the current cross-section positioning information can maintain a high degree of consistency, which is beneficial for assessing the disease progression of the object to be scanned based on the current magnetic resonance image.

[0104] Figure 5 This is a flowchart illustrating a magnetic resonance scanning method in another embodiment, as shown below. Figure 5 As shown, it includes the following steps:

[0105] S501, Obtain the initial pre-scanned medical image of the object to be scanned;

[0106] S502, The marker information in the initial pre-scanned medical image is processed to obtain the positioning result of the marker information;

[0107] S503, if the positioning result of the marker information meets the preset quality requirements, the marker information shall be used as the target marker information;

[0108] S504, if the positioning result of the marker information does not meet the preset quality requirements, the new marker information in the initial pre-scanned medical image is processed to obtain the positioning result of the new marker information;

[0109] S505, if the positioning result of the new marker information meets the preset quality requirements, the new marker information shall be used as the target marker information;

[0110] S506, when the target marking information includes a marking information, the initial pre-scanned medical image is sliced ​​according to the position information and orientation information of the target marking information to obtain initial slice positioning information;

[0111] S507, when the target marking information includes multiple marking information, the initial pre-scanned medical image is sliced ​​according to the position information of the multiple target marking information to obtain the initial slice positioning information;

[0112] S508, control the scanning device to scan the object based on the initial section positioning information to obtain the initial magnetic resonance image;

[0113] S509, Obtain the current pre-scanned medical image of the object being scanned;

[0114] S510, Perform slicing processing on the current pre-scanned medical image based on the target marking information to obtain the current slice positioning information;

[0115] S511, control the scanning device to scan the object based on the current cross-sectional positioning information to obtain the current magnetic resonance image.

[0116] In this embodiment, the target marker information is obtained by locating the marker information in the initial pre-scanned medical image. Further, based on the target marker information, the initial pre-scanned medical image is cross-sectionalized to obtain initial cross-sectional positioning information. The scanning device can then scan the object based on this initial cross-sectional positioning information to obtain an initial magnetic resonance image, avoiding the problem of inaccurate cross-sections caused by doctors directly scanning and acquiring magnetic resonance images. Moreover, the target marker information can cover the entire scanning cycle of the object, improving the accuracy of the magnetic resonance image while effectively reducing scanning time.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0118] Based on the same inventive concept, this application also provides a magnetic resonance scanning apparatus for implementing the magnetic resonance scanning method described above. The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more embodiments of the magnetic resonance scanning apparatus provided below can be found in the limitations of the magnetic resonance scanning method described above, and will not be repeated here.

[0119] In one exemplary embodiment, such as Figure 6 As shown, a magnetic resonance scanning device is provided, comprising: a first acquisition module 11, a positioning module 12, a first processing module 13, and a first control module 14, wherein:
