Description
Technical Field
The invention relates to the technical field of medical image processing, in particular to a method, a device and a system for displaying and updating an interactive tooth three-dimensional image.
Background
Cone Beam Computed Tomography (CBCT) is a diagnostic imaging technique that is widely used in the diagnosis of dental disease and in the study of dental problems. The tooth images in the CBCT images are typically segmented, either manually or automatically, to generate three-dimensional images for the dentist to view the slices, volumes, or shapes of the teeth, etc., to make more accurate diagnostic decisions and treatment plans. The lesion tissue and the normal tissue structure are displayed from a three-dimensional angle, and the defects of a two-dimensional plane, such as image overlapping, distortion, deformation and the like of normal tissues and organs, are avoided. The method is widely applied to alveolar bone surgery, dental pulp disease treatment, dental implant restoration, oral tumor diagnosis, periodontal disease diagnosis and treatment, orthodontic treatment, oral cosmetology, jaw orthodontic and other aspects.
In dental implant restoration, the three-dimensional CT image is used for checking the gum of a patient, and important information such as the width, thickness and height of an alveolar bone can be accurately obtained. The doctor not only can see the three-dimensional image of tooth directly perceived on the computer, can also switch different visual angles and observe the position relation between soft or hard tissue, avoids the danger area in the operation scheme, guarantees the security of operation. And the CT data can be used for reconstructing a digital model, an operation template is prepared in advance by matching with software, so that the implantation operation is safer and faster, and complications such as facial nerve paralysis, nasosinusitis and the like caused by careless damage to anatomical structures such as nerves, nasal sinuses and the like in the operation are avoided.
However, the CBCT is a unidirectional process for generating the tooth three-dimensional model, that is, the generated model is often only used for observation and diagnosis, and the generated three-dimensional model is displayed through the two-dimensional display screen, when a doctor needs to adjust the position or angle of the tooth model to simulate an operation scheme, the three-dimensional model before and after the change is displayed through the two-dimensional display screen, it is difficult to give a visual feeling to the doctor and observe the change, so that the model change in the three-dimensional space is controlled with great difficulty, certain defects exist in the aspect of medical guidance, and many hidden dangers and risks are brought to diagnosis and treatment.

And meanwhile, retrieving data marks in the original tooth three-dimensional image data, rendering the original tooth three-dimensional image data according to the data marks, generating three-dimensional models of all teeth corresponding to the data marks, and finally obtaining the three-dimensional models of all teeth by adopting a traversal retrieval mode, namely obtaining a plurality of first three-dimensional models corresponding to all teeth, wherein each first three-dimensional model represents the shape of one tooth, and displaying the three-dimensional models of all teeth on a user interface.
S301: a first operation is performed on at least one first three-dimensional model.
Operations including, but not limited to, rotation, movement, and deletion are performed on at least one or more of the first three-dimensional models corresponding to the respective teeth as desired. Since one first three-dimensional model corresponds to one tooth, each first three-dimensional model can be operated independently to realize independent interaction of each tooth.
S401: slice updating:
performing first processing on the data of the tooth three-dimensional image data subjected to the first operation to obtain changed post-processing tooth three-dimensional image data;
and generating and displaying an updated tooth slice image according to the post-processing tooth three-dimensional image data, and acquiring a plurality of changed second three-dimensional models.

Meanwhile, the post-processed tooth three-dimensional image data not only contains changed three-dimensional data obtained after one or more first three-dimensional models are operated, but also contains three-dimensional data corresponding to other first three-dimensional models which are not operated, and accordingly, the updated tooth slice image also displays a second three-dimensional model corresponding to the first three-dimensional model which is not operated, namely, the teeth which are not operated are also simultaneously displayed in the updated tooth slice image.
S501: repeating steps S301, S401 a plurality of times based on the plurality of second three-dimensional models.
In the same manner, steps S301 and S401 are repeated based on the plurality of second three-dimensional models obtained. Namely when the tooth three-dimensional model needs to be changed, the first operation is carried out on one or more second three-dimensional models, then the slice updating is carried out, on the basis of the second three-dimensional models, new updated tooth slice images are obtained and displayed, and meanwhile, a plurality of changed third three-dimensional models are obtained.

And each first three-dimensional model can be operated independently to realize independent interaction of each tooth.
In some embodiments, in order to better observe the change of the three-dimensional model before and after the change, a background image is set, and the tooth slice image obtained after each update is superposed on the background image, so that the change of the tooth slice image is more conveniently observed.
Specifically, the following scheme is adopted:
as shown in fig. 1, a method for displaying and updating an interactive three-dimensional image of teeth includes:
s101: obtaining intraoral CBCT image data and corresponding original tooth three-dimensional image data;

s501: repeating steps S301, S401 a plurality of times based on the plurality of second three-dimensional models.
Wherein the dimension of the original dental three-dimensional image data is the same as the dimension of the slice image data corresponding to the background image, so that the slice image of the three-dimensional data can be superimposed on the background slice image.
According to the technical scheme of the embodiment, the original tooth slice image can be superposed on the background image, the tooth slice image updated each time can be superposed on the background image, and the intraoral CBCT slice image is a picture containing teeth, periodontium and other tissues, so that the positions of the teeth in the mouth can be seen more clearly after the tooth slice image is superposed on the intraoral CBCT slice image, and the relative movement of the three-dimensional model can be observed.
Meanwhile, the tooth slice images updated each time are superposed on the background image, so that the tooth slice images are displayed in the same display area, and the relative change of the slice images can be found more accurately and intuitively.
The following describes the method for displaying and updating an interactive dental three-dimensional image according to an embodiment of the present invention in more detail with reference to fig. 2, 3 and 4.
Fig. 1 is a specific step of a method for displaying and updating a three-dimensional image and its slice in an embodiment of the present invention, first reading intraoral CBCT image data and generating an intraoral CBCT slice image, the intraoral CBCT slice image is taken as a background image and displayed, the displayed image is shown as 200 in fig. 2, the image 200 is divided into a top view 201, a front view 202 and a side view 203, and the slice images in the three directions all include a tooth and tissues around the tooth. The coordinate axis 204 in each of fig. 2 is drawn on the image for easy observation, and is not the slice image data, and such coordinate axes are present in fig. 3 and 4 as well, and is 305 in fig. 3 and 405 in fig. 4.
And then reading the original tooth three-dimensional image data, generating an original tooth slice image, superposing the original tooth slice image on the background image and displaying the original tooth slice image, and acquiring a three-dimensional model image, wherein an effect image is shown as 300 in fig. 3. FIG. 3 shows a more detailed view than FIG. 2, showing a three-dimensional model 304, the three-dimensional model 304 being a three-dimensional model map obtained from data of a three-dimensional image of an original tooth. It can be seen from this view 304 that there are a plurality of first three-dimensional models, each representing one of the teeth, and 306 one of the first three-dimensional models representing one of the teeth. Each first three-dimensional model may be independently moved or rotated.
The slices 301, 302, 303 in fig. 3 correspond to 201, 202, 203 in fig. 2, and the slices 301, 302, 303 are respectively a top view, a front view, and a side view; each of the slice images 301, 302, and 303 includes a background image, and other tissues around the periodontal pockets and periodontal pockets are visible from the background image, and the background image is superimposed on a tooth slice image corresponding to the three-dimensional image. The three slice images labeled 307, 308, 309 in fig. 3 are slice images from which different views of the first three-dimensional model 306 are reflected. Only a portion of the slice of the first three-dimensional model is visible in fig. 3 because the three-dimensional model is a spatial three-dimensional model and the slice coordinates of some models are not within the range shown in the current background slice 2.
The user moves the first three-dimensional model of a tooth or teeth, such as moving model 306 in fig. 3, through an interactive operation (e.g., translation, rotation, etc.), at 400 in fig. 4, at the location of the second three-dimensional model 406, i.e., the first three-dimensional model 306 and the second three-dimensional model 406 are images before and after the same tooth movement. The user then issues a command to update the slice images 301, 302 and 303, the updated corresponding images are the images 401, 402 and 403, and the updated images are also superimposed on the background image. Comparing fig. 3 and 4, it can be seen that the slice images 307, 308 and 309 corresponding to the first three-dimensional model 306 at the positions 407, 408 and 409 in fig. 4 are all disappeared, the background slice image is displayed at the three positions 407, 408 and 409 instead of the slice image of the model 306, and a new slice image 410 appears, which is a visual representation of the second three-dimensional model 406 on the slice image after the movement.
