The invention provides a method and system for generating a head anterior position image and a side position image based on a CBCT image, and the method comprises the following steps: obtaining image data of a target head through CBCT; importing an image reconstruction algorithm; obtaining a three-dimensional image of the target head according to an image reconstruction algorithm and the image data; obtaining a soft tissue image and a bone tissue image of the target head according to the three-dimensional image; and obtaining a lateral image and a normal image of the target head according to the soft tissue image, the bone tissue image and the three-dimensional image. According to the invention, the phenomenon of bone tissue overlapping in the normal position image and the lateral position image of the target head can be effectively avoided, so that the quality of the lateral position image and the normal position image of the target head can be improved; through CBCT sampling, the positioning requirement on the head of the target can be reduced, and secondary scanning on the target is avoided; therefore, extra radiation to the target can be avoided.
Description
technical field [0001] The present invention relates to the technical field of CBCT image processing, in particular to a method for generating an anteroposterior image and a lateral image of a head based on a CBCT image and a system for generating an anteroposterior image and a lateral image of a head based on a CBCT image. Background technique [0002] Currently, lateral and frontal cephalometric imaging uses X-rays to irradiate the patient's head from the side or the front, so as to obtain lateral and frontal structural images of the skull. However, the resulting structural image is generally a two-dimensional projection image, and in the two-dimensional projection image, teeth and teeth, teeth and vertebrae and other bony tissues often overlap, which makes it impossible to distinguish skull landmarks. [0003] In addition, the current lateral and frontal imaging have relatively high requirements for the positioning of the patient's head, especially the lateral imaging is ...
