[0051] Medical diagnostic imaging is a discipline that enables clinical diagnosis based on the accurate identification of anatomical structures in images. The course's content and objectives are to help students identify anatomical structures in images, understand and learn about diseases, and enhance their ability to analyze and diagnose them. It is highly practical. The teaching method combines theoretical instruction with hands-on learning using molds. Traditional teaching molds are limited in source, lack a visual representation of complex anatomical structures, are limited in the number of diseases, are often difficult to replace after damage, and some molds even distort details, hindering the further development of classical diagnostic imaging teaching.

[0052] 3D printing technology, also known as rapid prototyping, offers advantages in clinical medicine, medical education, and medical research, such as a wide range of available molds and a diverse range of types. Currently, it has achieved promising results in medical education and clinical treatment related to the production of tissue and organ models. Currently, 3D printing technology is being integrated with modern medical imaging technologies, primarily through 3D printing based on three-dimensional reconstruction of CT and MRI image data. Medical 3D printed models are characterized by precision, personalization, and specificity, and have been widely used in related fields such as orthopedics, plastic surgery, cardiovascular and cerebrovascular diseases, and urology.

[0053] Research has shown that 3D printed models can help students deepen their understanding of medical imaging. However, the 3D printed models currently used are based on CT or MR three-dimensional reconstructions. Because sectional images are two-dimensional, students' brains must undergo a process of transformation from two-dimensional images to three-dimensional models when using these models. This limits the application of 3D printed models in imaging education, as 3D printed models based on three-dimensional images cannot accurately correspond to the images.

[0054] Based on this, the present application provides a method for generating a tomographic image anatomical model, which includes the following steps:

[0055] Step 101, obtaining three-dimensional simulation model information of a target object;

[0056] Specifically, the target object can be a target organ. When designing a sectional imaging anatomical model, three-dimensional modeling is required to establish a three-dimensional simulation model of the organ so that the sectional imaging anatomical model can be assembled into a complete 3D model to meet teaching needs.

[0057] Furthermore, the terminal can acquire multiple historical tomographic images and perform 3D modeling based on these historical image information, thereby obtaining data information for a 3D simulation model of an internal organ. This 3D modeling based on historical image information also ensures that the slicing module 310 can construct a complete 3D model, making the tomographic image anatomical model suitable for both tomographic image teaching and 3D anatomical model teaching, thereby increasing the applicability of the tomographic image anatomical model.

[0058] Step 102: determining the position information of the slice plane of the target object based on the target tomographic image information, and dividing the three-dimensional simulation model of the target object into multiple slice simulation models based on the position information of the slice plane to obtain multiple slice simulation model information;

[0059] Specifically, by determining the position of the target tomographic image in the 3D simulation model based on the image information of the target tomographic image, the position information of the slice plane can be determined. Therefore, the 2D image information corresponding to the slice plane corresponds to the target tomographic image information one-to-one.

[0060] Furthermore, there may be multiple target tomographic image information. Based on the multiple target image information, multiple slice plane positions can be determined. Based on the position information of two adjacent slice planes, the thickness of the corresponding slice module 310 can be determined. The terminal can set the thickness of the slice module 310 on its own, but it is necessary to ensure that at least one slice plane of the slice module 310 corresponds to the target tomographic image information;

[0061] Furthermore, based on the position information of the slice planes, segmentation position information of the 3D simulation model is determined, and the 3D simulation model is segmented based on the segmentation position information to obtain multiple slice simulation model information. The slice simulation model information corresponds one-to-one with the slice modules 310, which facilitates assembling the slice modules 310 into a 3D model, achieving conversion from a 2D image to a 3D model, improving conversion efficiency, and reducing the difficulty for students to understand during teaching.

[0062] Step 103: determining the serial number information corresponding to each slice simulation model according to the three-dimensional simulation model information and the plurality of slice simulation model information;

[0063] Specifically, the multiple sliced ​​simulation models obtained by segmentation can be sorted according to a preset target order based on the three-dimensional simulation model, so that the slice modules 310 can be printed in order during the printing process. This method also facilitates the orderly assembly of the slice modules 310 according to the sequence number in practice, thereby improving the assembly efficiency of the slice modules 310.

[0064] Furthermore, the preset order needs to be based on the information of the slice plane. For example, if the slice plane is horizontal, it needs to be sorted in the vertical direction from top to bottom or from bottom to top.

[0065] Step 104, determining the position information of the connecting device of each slice simulation model according to the target tomographic image information and preset rules;

[0066] Specifically, considering that the location of the connection device 320 may interfere with the accurate alignment of the model with the target tomographic image, the terminal needs to place the connection device 320 in a non-critical area according to preset rules. The slice surface area corresponding to the area of ​​the target tomographic image that needs to be analyzed is the critical area, and the slice surface area corresponding to the area of ​​the target tomographic image that does not need to be analyzed is the non-critical area.

[0067] Furthermore, non-critical areas of each slice are determined based on the target tomographic image information, and a number of connecting devices 320 are installed as needed. There is no limit on the number of connecting devices 320 per slice. Connecting devices 320 can be conventional snap-fit ​​structures, or they can be provided with connecting grooves 420 for receiving connecting material 410. Once the location of connecting devices 320 is determined, the shape of connecting devices 320 can be designed as needed to meet the needs of different teaching scenarios.

[0068] Step 105 : Outputting a printing instruction based on the multiple slice simulation model information, sequence number information, and position information. The printing instruction is used to obtain multiple slice modules 310 .

[0069] Specifically, after determining the multiple slice simulation model information, sequence information, and location information, the terminal can output a print instruction to obtain multiple slice modules 310. The slice plane of each slice module 310 corresponds to the target tomographic image. The connecting device 320 located on the slice plane of the slice module 310 facilitates the assembly of the slice modules 310 into a complete organ model.

[0070] Therefore, in the above-mentioned tomographic image anatomical model generation method, the three-dimensional simulation model information of the target object is obtained, and the position information of the slice surface, multiple slice simulation model information, serial number information corresponding to each slice simulation model and the position information of the connecting device 320 are determined in sequence according to the target tomographic image information and the three-dimensional simulation model information, and a printing instruction is output to obtain multiple slice modules 310, thereby improving the accuracy of the correspondence between the printed model and the target tomographic image information, and also realizing the assembly and restoration of the slice modules 310 into a three-dimensional model, realizing the conversion of two-dimensional images to three-dimensional images and the conversion of tomographic anatomy to gross anatomy, thereby improving the applicable scenarios of the model.

[0071] In one embodiment of the present application, in step 104, the preset rules include a first preset rule and a second preset rule, and determining the position information of the connecting device of each slice simulation model based on the target tomographic image information includes:

[0072] Determining target region information of each slice simulation model according to target tomographic image information and a first preset rule;

[0073] According to the target area information and the second preset rule, the position information of the connecting device of each slice simulation model is determined.

[0074] Specifically, the first preset rule is a rule for dividing important and unimportant areas. The slice plane regions corresponding to the areas of the target tomographic image that require analysis are considered important areas, while the slice plane regions corresponding to the areas of the target tomographic image that do not require analysis are considered unimportant areas. Considering that the location of the connecting device 320 may interfere with the precise alignment between the model and the target tomographic image, the terminal determines the target region information for each slice simulation model, i.e., the unimportant regions corresponding to the slice planes of the slice simulation model, according to the first preset rule.

[0075] Furthermore, the first preset rule is for the shape and number of connecting devices. Based on the target area information for each slice simulation model, the terminal sets a number of connecting devices 320 as needed. There is no limit on the number of connecting devices 320 per slice surface, and the shape of the connecting devices 320 can be designed as needed to meet the needs of different teaching scenarios.

[0076] In one embodiment of the present application, Figure 2 As shown, the above step 105 outputs a printing instruction based on the multiple slice simulation model information, sequence information and position information. The printing instruction is used to obtain multiple slice modules 310, including:

[0077] Step 201: Print multiple slice modules 310 based on multiple slice simulation model information, serial number information, and position information, and establish a slice simulation model information table, which includes a correspondence between the slice simulation model information, serial number information, and position information;

[0078] Specifically, the terminal can establish a simulation model information table based on the slice simulation model information, serial number information and position information of the connection device 320 of the slice surface corresponding to each slice simulation model, so that the information of each slice simulation model is complete, which is convenient for ensuring accuracy during the printing process.

[0079] Step 202 : Outputting a printing instruction according to the first preset sequence and the slice simulation model information table, where the printing instruction is used to obtain a plurality of slice modules 310 .

[0080] Specifically, the first preset sequence can be arranged in ascending order as needed, and according to the information in the table corresponding to each sequence, a printing instruction is output to obtain the corresponding slice module 310. The printing method can be 3D printing or other printing methods. After the terminal completes printing and obtains multiple slice modules 310, the slice modules 310 can be used directly in tomographic imaging teaching, or they can be assembled and applied in three-dimensional anatomy teaching.

[0081] In the above-mentioned method for generating a tomographic image anatomical model, the three-dimensional simulation model information of the target object is obtained, and the position information of the slice surface, multiple slice simulation model information, serial number information corresponding to each slice simulation model and the position information of the connecting device 320 are determined in sequence according to the target tomographic image information and the three-dimensional simulation model information, and a printing instruction is output to obtain multiple slice modules 310, thereby improving the accuracy of the correspondence between the printed model and the target tomographic image information, and also realizing the assembly and restoration of the slice modules 310 into a three-dimensional model, realizing the conversion of two-dimensional images to three-dimensional images and the conversion of tomographic anatomy to gross anatomy, thereby improving the applicable scenarios of the model.

[0082] It should be understood that, although the various steps in the flowcharts involved in the above embodiments are shown in sequence as indicated by the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0083] In one embodiment of the present application, Figure 3 As shown, a cross-sectional imaging anatomical model is provided, which includes:

[0084] A plurality of slicing modules 310, wherein a slicing plane of each slicing module 310 corresponds to a target tomographic image;

[0085] The connecting device 320 is located on the slicing surface of each slicing module 310 and is used to connect the multiple slicing modules 310 according to a second preset order.

[0086] Specifically, the tomographic imaging anatomical model is a complete 3D printed model with the complete shape of the organ. The tomographic imaging anatomical model includes a plurality of slicing modules 310, and the slicing plane of each slicing module 310 corresponds to the target tomographic image. The number of slicing planes can be consistent with the number of target tomographic images. A connecting device 320 is provided on the slicing plane of each slicing module 310 to facilitate the assembly of the slicing modules 310 into a complete organ model. The connecting device 320 is located on the slicing plane, and the connecting device 320 can be a common snap-fit ​​structure. When connecting two slicing modules 310, the assembly and disassembly of the slicing module 310 can be completed directly through the snap-fit ​​structure.

[0087] Therefore, in the aforementioned sectional imaging anatomical model, the slicing plane of each of the multiple slicing modules 310 corresponds to the target sectional image; the connecting device 320 is located on the slicing plane of each slicing module 310 and is used to connect the multiple slicing modules 310 in a second predetermined order. This sectional imaging anatomical model not only achieves precise correspondence between the slicing modules 310 and the target sectional image, but also enables the assembling and restoration of the slicing modules 310 into a three-dimensional model, achieving conversion from a two-dimensional image to a three-dimensional image and from sectional anatomy to gross anatomy. This overcomes the problems in the prior art of printed models that cannot precisely correspond to sectional images and cannot convert two-dimensional images into three-dimensional models.

[0088] In one embodiment of the present application, Figure 4 As shown, the connecting device 320 includes:

[0089] Connecting material 410, used to connect multiple slicing modules 310;

[0090] The connection groove 420 is located on the slicing surface of each slicing module 310 and is used to place the connection material 410.

[0091] Specifically, the connecting device 320 may include a connecting material 410 and a connecting groove 420. The connecting groove 420 is provided on each slice plane. Considering that the location of the connecting device 320 may interfere with the accurate alignment of the model with the target tomographic image, it is necessary to place the connecting device 320 in a non-critical area. The slice plane areas corresponding to the target tomographic image requiring analysis are considered critical areas, while the slice plane areas corresponding to the target tomographic image requiring no analysis are considered non-critical areas. Adding the connecting material 410 to the connecting groove 420 improves the efficiency of converting 2D images into 3D models.

[0092] Furthermore, the connecting material 410 can make the model easy to assemble and disassemble, thereby improving the applicable scenarios of the above-mentioned model, so that the model can be applied not only to anatomy teaching, but also to tomographic imaging teaching.

[0093] In one embodiment of the present application, the connecting material 410 is a magnet, and the connecting groove 420 is a magnet hole.

[0094] Specifically, the connecting material 410 is a magnet sheet, and the connecting groove 420 is a placement groove having the same shape as the magnet sheet, which facilitates the placement of the magnet sheet.

[0095] Furthermore, the connecting material 410 may also include other materials with magnetic force, which can make the model easy to disassemble and assemble to meet the needs of different teaching scenarios.

[0096] Based on the same inventive concept, embodiments of the present application further provide a device for generating a tomographic anatomical model using a tomographic imaging method for implementing the aforementioned method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more embodiments of the device for generating a tomographic anatomical model provided below can be found in the aforementioned limitations of the method for generating a tomographic anatomical model, and will not be further elaborated here.
