In the system, various medical images (including images generated by equipment such as nuclear magnetism, computed tomography, digital X-ray, ultrasound, various X-ray machines and the like) generated in daily life by a hospital imaging department are stored according to medical digital imaging and communication standards. For more details on processing medical image data to obtain a three-dimensional model, please refer to fig. 4 and the related description thereof, which are not repeated herein.

In some embodiments, the standard reference image may comprise a DR two-dimensional image (e.g., a DR surview). In some embodiments, the standard reference image may include labeled content information such as a Cobbe angle from which the severity of lateral bending of the whole or part of the tissue of the human or animal may be assessed, so that it may be determined whether to perform a brace treatment or a surgical treatment on the human or animal. For example, when clinically evaluating the severity of scoliosis using the Cobbe angle, if the Cobbe angle reflected on the standard reference image is 20 ° to 45 °, a brace therapy is selected; if the Cobbe angle exceeds 45 °, surgical treatment is considered. In some embodiments, the second acquiring module 220 may acquire a standard reference image of the part to be corrected, which is obtained by, but not limited to, laser scanning or optical scanning of a DR device, an X-ray machine, a camera, and the like. For example, a standard reference image of the part to be corrected is pre-stored in a DR device, an X-ray machine, a camera, or the like, and the second obtaining module 220 obtains the standard reference image. For another example, the DR device, the X-ray machine, and the camera may directly transmit the captured standard reference image to the second acquisition module 220. In some embodiments, the second obtaining module 220 may query, according to the user information of the part to be corrected, the user information closest to the user information of the part to be corrected in the historical image, so as to obtain the corresponding standard reference image. In some embodiments, the second obtaining module 220 may also train the initial model according to the historical images to obtain an image generation model, and input the user information of the part to be corrected into the image generation model to obtain the standard reference image.

In some embodiments, the instructions to acquire the standard reference image of the part to be corrected may be stored in a storage device (e.g., storage device 150) and may be invoked by the processing device 200 (e.g., second acquisition module 220).

In some embodiments, the design data acquisition module 230 may cross-reference the three-dimensional model to a standard reference image. In some embodiments, the collation may include an overlay display. Specifically, the process of displaying the overlay may include determining the feature points or the reference points in the three-dimensional model and the standard reference image, and then overlaying based on the reference points (the reference points are aligned) of the two. In some embodiments, the design data acquisition module 230 can also acquire orthosis design data resulting from editing the three-dimensional model based on the results of the standard reference images and/or the controls. Specifically, the orthosis design data may include, but is not limited to, results of one or more of mesh deformation, mesh smoothing, mesh subdivision, and mesh cropping of the three-dimensional model. In some embodiments, editing the three-dimensional model to obtain the orthotic design data can be performed by an orthotic designer based on the comparison of the three-dimensional model and the standard reference image, and then manually inputting corresponding parameters into the design data obtaining module 230 to obtain the orthotic design data.

The method for generating the orthosis according to the standard reference image and the three-dimensional model comprises the following specific steps: superimposing a standard reference image on the three-dimensional model, as shown in fig. 7, wherein the standard reference image is a DR image (DR plain film) of the torso of the target object; and then editing the grid of the three-dimensional model according to the superposition effect of the standard reference image and the three-dimensional model to obtain the orthosis, wherein the editing comprises at least one editing operation of grid deformation, grid smoothing, grid subdivision and grid cutting.

In particular, the orthosis generated for a target subject of scoliosis can be referred to the schematic diagram shown in fig. 8. The method mainly comprises the steps of carrying out mesh deformation editing on meshes in a pressure area, cutting the meshes according to the requirements of different parts of an orthosis, and carrying out mesh smoothing, mesh subdivision and other operations on the rest parts.

In some embodiments, the instructions to obtain orthotic design data may be stored in a storage device (e.g., storage 150) and may be invoked by cloud design system 140 (e.g., data interaction device 141).

In some embodiments, the orthosis design method 300 can further include modifying the orthosis design data to provide a higher degree of fit between the three-dimensional model of the site to be corrected and an orthosis constructed from the orthosis design data. For more details on the correction of the appliance design data, please refer to fig. 5 and the related description thereof, which are not repeated herein.

According to the technical scheme of the embodiment, the orthotics are designed and generated by the server according to the orthotics design instruction and the three-dimensional model of the part to be corrected, which are obtained at the network access port, and then the standard reference image of the part to be corrected and the three-dimensional model are combined, so that the problems of complex design process and low efficiency of the orthotics in the prior art are solved; the method and the device can realize that a user only accesses the server for designing the orthosis through the network access port to complete the orthosis design on the part to be corrected of the target object, simplify the process of designing the orthosis and enable the orthosis design to be more efficient.

After the generated orthosis or the corrected (or called modified) orthosis is obtained, a shell model is generated, namely the thickness of the orthosis is determined, and an orthosis shell with a certain thickness is created. Reference may be made to the orthosis shown in fig. 8.

In some embodiments, orthosis design method 300 can further include thickness processing of the orthosis design data. In particular, the processing device 200 (e.g., the thickness processing module 250) can perform thickness processing based on the orthotic design data, resulting in processed orthotic shell data. In some embodiments, the processing device 200 (e.g., the storage module 260) can also be used to store the orthosis shell data at the user terminal. In some embodiments, a processing device 200 (e.g., upload module 270) can be used to upload the orthotic shell data to a server. In some embodiments, the orthosis shell data can be used to represent the size of the orthosis. Such as the length, width, height, and thickness of the brace, etc. In some embodiments, the brace can have a thickness of 3-4 mm.

In some embodiments, the server that uploads the orthotic shell data may comprise a 3D print server. The 3D print server can be used to connect a 3D printing device to print an orthotic based on orthotic shell data. In some embodiments, the orthosis can be an extracorporeal appliance fitted to the site to be corrected, the appliance having a thickness similar to the shape of the shell.

Specifically, the server for designing the orthosis can be directly connected with the 3D printing server with a communication protocol, so that the designed orthosis and 3D printing parameters and the like can be directly sent to the 3D printing cloud server, the shell model of the orthosis can be printed by connecting the 3D printing equipment, and the whole process from the design of the orthosis to the printing of the shell model as the entity orthosis can be completed.

According to the technical scheme of the embodiment, the server generates the orthosis according to the orthosis design instruction and the three-dimensional model of the part to be corrected, which are acquired from the network access port, and the standard reference image of the part to be corrected and the three-dimensional model design are combined, so that the shell model of the orthosis is sent to the 3D printing cloud server to complete the printing of the orthosis, and the problems of complex design process and low efficiency of the orthosis in the prior art are solved; the method and the system can enable a user to access the server for designing the orthosis only through the network access port to complete the whole process of designing and printing the orthosis on the part to be corrected of the target object, simplify the process of designing the orthosis and producing the orthosis, and enable the design of the orthosis to be more efficient.

In some embodiments, the medical image data may include, but is not limited to, a combination of one or more of a magnetic resonance imaging image, a computed tomography image, a digital radiographic image, and a computer X-ray image. In some embodiments, the medical image data may also include a dataset of multiple tomographic images (e.g., a 3D medical image) that may be superimposed as a basis for three-dimensional model generation. In some embodiments, the first acquisition module 210 may acquire medical image data from a PACS.

In some embodiments, the medical image data may employ Digital imaging and Communications in Medicine (DICOM) as a standard for storing and exchanging medical image data. DICOM defines a medical image format for data exchange that meets clinical requirements in quality using specific file formats and communication protocols. In particular, the medical image may be saved in a DICOM file format. In addition to data relating to medical images (e.g., device data from which images are taken and medical background data), the DICOM file format data may also store protected information about the person being scanned, such as name, gender, age, and identity ID (e.g., identification number). In some embodiments, a medical imaging device (e.g., a CT device, a DR device, an MRI device, a 3D scanner) for capturing medical images may create the scanned medical images into a DICOM file format, and a doctor or an orthosis designer may read the medical images in the DICOM file format using a viewer having a function of reading the DICOM file to determine information carried in the medical images. In some embodiments, the data in DICOM file format may also include exchanging information other than DICOM image information, such as patient information and surgical information, among others. In some embodiments, the patient information may be the age, sex, weight, past medical history, etc. of the patient. In some embodiments, the surgical information may be a surgical start time, an expected end time, a surgical procedure flow, and the like.

In some embodiments, the instructions to acquire medical image data may be stored in a storage device (e.g., storage device 150) and may be invoked by processing device 200 (e.g., first acquisition module 210).

In some embodiments, the three-dimensional model acquisition method 400 may further include preprocessing the medical image data, including: and image segmentation, filtering, smoothing, mesh generation and the like. Further processing of the medical image data can be seen in steps 420-440.

And step 420, performing image segmentation on the medical image data to acquire a region of the part to be corrected. Specifically, step 420 may be performed by the first obtaining module 210.

In some embodiments, the image segmentation method may include, but is not limited to, one or more combinations of threshold segmentation, edge segmentation, region segmentation, motion segmentation, active contour model-based segmentation, fuzzy clustering algorithm-based segmentation, wavelet transform-based segmentation methods, and the like. In some embodiments, the thresholding may include histogram thresholding, inter-class variance thresholding, two-dimensional maximum entropy segmentation, and fuzzy thresholding. In some embodiments, region segmentation may include region segmentation-region growing, region splitting-merging methods, and the like. In some embodiments, the region of the part to be corrected may include a region of the part to be corrected in the medical image data. In some embodiments, the first acquisition module 210 performs image segmentation on the medical image data to acquire a region of the site to be corrected.

In some embodiments, the instructions to perform image segmentation on the medical image data may be stored in a storage device (e.g., storage device 150) and may be invoked by the processing device 200 (e.g., first acquisition module 210).

And step 430, extracting body surface data of the region of the part to be corrected. In particular, step 430 may be performed by the first obtaining module 210.

In some embodiments, the body surface data may be pixel points of a body surface contour (e.g., skin contour) obtained after image segmentation. In some embodiments, the body surface data may be a mask. Specifically, the mask may be, but is not limited to, a mask, a two-dimensional matrix array, a multi-valued image, or the like. In some embodiments, the first obtaining module 210 may extract body surface data in the medical image data after image segmentation of the medical image data. In some embodiments, the first obtaining module 210 may further delete impurity points (e.g., pixels of clothes, ornaments, etc.) existing in the body surface data, so as to extract the body surface data more convenient for the three-dimensional model construction.

In some embodiments, step 430 may also include preprocessing the body surface data. In some embodiments, preprocessing the body surface data may include, but is not limited to, one or more combinations of smoothing, filtering, and boundary calculation.

In some embodiments, the instruction for extracting the body surface data of the region to be corrected may be stored in a storage device (e.g., the storage device 150) and may be invoked by the processing device 200 (e.g., the first obtaining module 210).

Step 440, generating a grid based on the body surface data of the region to be corrected. Specifically, step 440 may be performed by the first obtaining module 210.

In some embodiments, the mesh may be formed by stitching a plurality of feature point data of the body surface data of the region to be corrected. Specifically, a plurality of feature points of the body surface data may be connected into a plurality of facets, and then the facets may be spliced to form the three-dimensional model mesh. In some embodiments, the feature point data may be pixel points of a body surface contour of the region to be corrected. In some embodiments, the facets may be triangular, quadrilateral, or other concave or convex polygonal planes, which may simplify the rendering (display) process by stitching a plurality of facets to form a three-dimensional model mesh.

In some embodiments, the instructions to generate the grid may be stored in a storage device (e.g., storage device 150) and may be invoked by processing device 200 (e.g., first acquisition module 210).

The grid is composed of a plurality of point clouds of an object, a three-dimensional model grid is formed through the point clouds, and point cloud data, namely body surface data of the trunk part of the target object, are acquired in the method. These meshes are usually composed of triangles, quadrilaterals or other simple convex polygons, which may simplify the rendering process.

It should be noted that the above description of flow 400 and the description thereof are provided for illustrative purposes only and are not intended to limit the scope of the present application. Various modifications and changes may occur to those skilled in the art in light of the description herein. However, such modifications and changes do not depart from the scope of the present application. For example, step 410 and step 420 in three-dimensional model acquisition method 400 may be performed simultaneously.

Preferably, the orthosis can be corrected (or referred to as modified) based on the three-dimensional model, that is, whether the three-dimensional model of the part to be corrected is matched with the orthosis or not is compared, so that the three-dimensional model and the orthosis are completely matched, and if a difference exists between the two, the orthosis can be edited, so that the orthosis is matched with the three-dimensional model. Orthosis here means orthosis design data. For more details of processing medical image data, reference is made to fig. 5 and its description.

Fig. 5 is an exemplary flow chart of an orthosis modification method 500 according to yet another embodiment of the present application. In particular, the orthosis modification method 500 can be performed by the processing device 200. For example, the orthosis modification method 500 can be stored in a memory device (e.g., the memory device 150) in the form of a program or instructions that when executed by the orthosis design system 100 (e.g., the processing device 200) can implement the orthosis modification method 500. As shown in fig. 5, the orthosis modification method 500 can include:

step 510, based on the three-dimensional model of the part to be corrected and the design data of the orthosis, simulating stress data of one or more areas of the part to be corrected after wearing the orthosis. Specifically, step 510 may be performed by design data modification module 240.

In some embodiments, the force data may include the force magnitude and the force direction of one or more regions of the part to be corrected after wearing the corrector, and the force data may be obtained by simulation of the design data modification module 240. Specifically, a three-dimensional model of the orthosis can be generated according to the design data of the orthosis, and after the three-dimensional model of the part to be corrected is worn by the three-dimensional model of the orthosis, the stress data of the three-dimensional model of the part to be corrected is simulated. For example, after the corrector is worn on the part to be corrected, the bending degree of the three-dimensional model mesh of the part to be corrected can be simulated to perform stress calculation, and corresponding stress data can be obtained. The three-dimensional model of the orthosis has different force generation sizes and directions in areas where different grids of the three-dimensional model of the part to be corrected are located, and the force generation sizes and the force generation directions of the different grids of the three-dimensional model of the part to be corrected can be obtained by simulating the force data of one or more areas of the part to be corrected after the orthosis is worn. Specifically, the stress magnitude may be displayed in different colors, and further, the preset stress may be set, and the relative stress magnitude may be displayed in different colors, for example, red is used to indicate that the stress is too large, and blue is used to indicate that the stress is too small. The preset stress of the different grids may be the acting force exerted by the three-dimensional model of the orthosis on the different grids of the three-dimensional model of the part to be corrected, the preset stress and the preset force are a pair of forces having the same magnitude and the same direction, and further description about the preset force may be found in step 520. In some embodiments, the design data modification module 240 can simulate stress data of one or more areas of the part to be corrected after wearing the orthosis based on the three-dimensional model of the part to be corrected and the orthosis design data.

In some embodiments, the instructions to simulate the force data may be stored in a storage device (e.g., storage 150) and may be invoked by cloud design system 140 (e.g., design data modification module 240).

Step 520, obtaining the design data of the orthosis after being corrected according to the stress data of one or more areas of the part to be corrected. Specifically, step 520 may be performed by design data modification module 240.

In some embodiments, the orthosis design data can be modified according to the force data of one or more regions of the site to be corrected. Specifically, the orthosis design data can be corrected according to the stress magnitude and stress direction of different grids of the three-dimensional model of the part to be corrected and the preset force application of the three-dimensional model of the orthosis. In some embodiments, the preset force of the three-dimensional model of the orthosis can be the force applied by the pressure area of the orthosis to different areas of the part to be corrected during correction, and the preset force can be obtained according to clinical data statistics. In some embodiments, the predetermined force may also be predicted by a trained machine learning model. The calibration process will be explained below with a specific example: a certain triangular plane exists on the three-dimensional model of the part to be corrected, and the triangular plane is positioned at the position d when the three-dimensional model of the wearing orthosis is not simulated, and the stress is 0; after the three-dimensional model of the wearing orthosis is simulated, the triangular plane is located at a position e, the stress is A, the preset force applied to the triangular plane by the three-dimensional model of the orthosis is B, and the size of B is different from that of A, wherein when B is larger than A, the stress of the triangular plane after the orthosis is simulated to be worn is insufficient (blue can be represented at the position e), the design data of the orthosis needs to be adjusted to increase the stress to the triangular plane (namely, the bending degree of the three-dimensional model grid where the triangular plane is located is increased), and the blue is gradually lightened or directly changed from blue to transparent color in the process of increasing the stress of the triangular plane; conversely, when B is smaller than a, it means that the stress on the triangular plane is too large (red can be used to indicate e), the design data of the orthosis needs to be adjusted to reduce the stress on the triangular plane (i.e. the degree of curvature of the three-dimensional model mesh where the triangular plane is located is reduced), and the red color gradually becomes lighter or directly changes from red to transparent color in the process of increasing the stress on the triangular plane. The force A applied by the three-dimensional model of the orthosis to the triangular plane is close to the preset force B by adjusting the design data of the orthosis, so that the stress of the triangular plane at the position e is the same as or similar to the preset force, and by analogy, the whole grid (or pressure area) is traversed to obtain the design data of the corrected orthosis, so that the orthosis manufactured according to the design data of the corrected orthosis can be better matched with the part to be corrected, and the corrected orthosis can achieve the expected correction effect. In some embodiments, the design data modification module 240 may simulate the force data of one or more areas of the part to be corrected after wearing the orthosis, thereby obtaining the design data of the orthosis after modification according to the force data of one or more areas of the part to be corrected.

In some embodiments, the revised orthotic design data can be further confirmed by a physician or orthotic designer. If the doctor or the orthosis designer deems that the orthosis design data cannot meet the correction requirements, the data can be further corrected by the doctor or the orthosis designer until the requirements are met.

In some embodiments, the instructions to obtain the revised orthotic design data may be stored in a storage device (e.g., storage 150) and may be invoked by cloud design system 140 (e.g., design data revision module 240).

It should be noted that the above description of flow 500 and the description thereof are provided for illustrative purposes only and are not intended to limit the scope of the present application. Various modifications and changes may occur to those skilled in the art in light of the description herein. However, such modifications and changes do not depart from the scope of the present application. For example, in step 510, the trained machine learning model may be used to perform a force calculation, so as to obtain force data of one or more regions of the part to be corrected after wearing the corrector.

Specifically, the technical solution of this embodiment may be in a network structure mode of a B/S structure (Browser/Server mode).

In some embodiments, cloud design system 140 may also include file server 145. The file server 145 may be used to store image data captured by one or more data acquisition devices 110. In some embodiments, the data acquisition device 110 may be, but is not limited to, a DR device, a 3D camera, a CT device, an MRI device, and the like. In some embodiments, file server 145 may also be a PACS system.

In some embodiments, the data interaction apparatuses 141-143 may include a first level load balancing device 141, a cluster of data interaction devices 142, and a second level load balancing device 143. In some embodiments, the cluster of data interaction devices 142 may include a data interaction device 142-1, a data interaction device 142-2, and a data interaction device 142-3. In some embodiments, the terminal device 130 can perform data interaction with the data interaction devices 141-143 through a browser.

In some embodiments, the first level load balancing device 141 may have data interaction with the end device 130. Specifically, the first level load balancing device 141 can be configured to receive data sent by one or more terminal devices 130 and send a received orthosis design request to one or more data processing devices 144-1 to 144-3 in the data interaction device cluster based on a load balancing mechanism. In some embodiments, the data transmitted by one or more of the terminal devices 130 can be data related to an orthosis design request. In some embodiments, the load balancing mechanism may be configured to balance and distribute loads (or work tasks) to a plurality of data processing devices for execution, so as to jointly complete the work tasks. In some embodiments, the terminal device 130 may interact with the first level load balancing device 141 through a browser.

In some embodiments, the data interaction devices 142-1-142-3 can be used to determine orthosis design requests based on data from the terminal devices. In some embodiments, the orthosis design request can include, but is not limited to, one or more of medical image data of the site to be corrected, a three-dimensional model of the site to be corrected and/or a standard reference image of the site to be corrected, a patient ID (e.g., identification number) of the site to be corrected, and a description of the site to be corrected (e.g., left calf tibia, 3 rd to 6 th lumbar vertebrae).

In some embodiments, the second level load balancing device 143 and the one or more data processing devices 144-1-144-3 can have a signal connection for sending the received orthosis design request to the one or more data processing devices 144-1-144-3 based on a load balancing mechanism.

In some embodiments, data processing device cluster 144 may include data processing device 144-1, data processing device 144-2, and data processing device 144-3. In some embodiments, the data processing devices 144-1-144-3 can be in signal connection with at least one data acquisition device 110 and configured to perform the orthosis design method 300 or orthosis design method 500 based on an orthosis design request to obtain orthosis design data. In some embodiments, the data processing devices 144-1-144-3 can invoke the relevant image data by the data acquisition device 110 based on orthosis design requests. In some embodiments, the data processing devices 144-1-144-3 may also obtain relevant image data from the file server 145.

When a user needs to design an orthosis, the task of designing the orthosis requested and established by the load balancing server can be accessed through a network port such as a terminal browser, and when the load balancing server receives the request of the user and the task of designing the orthosis, the task is issued to the orthosis designing server (namely, the data processing equipment cluster 144), and the orthosis designing server receives a corresponding instruction for designing the orthosis for a target object. When a plurality of users request and establish a task of designing the orthotics to the access load balancing server at the same time, the load balancing server can balance and distribute network resource loads of the orthotics designing server according to a preset load balancing strategy, so that the plurality of orthotics designing servers can synchronously process the tasks of designing the orthotics of different terminals. For example, by a orthosis design server polling mechanism, a design orthosis task is distributed to an orthosis design server that is idle or has a relatively small amount of tasks.
