Problems solved by technology

Therefore, this method of enriching the lesion vessel model library is greatly limited in terms of data sources
In addition, the vascular digital model obtained by 3D reconstruction often requires a lot of manpower for manual processing and adjustment to meet the standard of use in virtual surgery. The cost of manpower and material resources for this work is also high, and the cycle is long

Abstract

The invention discloses a method and an apparatus for editing a tumor lesion of a blood vessel digital model. The method comprises the following steps: determining the position of a tumor selected on the blood vessel digital model; generating a virtual sphere with the position of the tumor selected on the blood vessel digital model as the center of the sphere and a radius of a hole at the intersection place between the tumor and the blood vessel digital model as the radius of the sphere; conducting collision detection between the virtual sphere and the blood vessel digital model to acquire all triangle surface patches which intersect with the virtual sphere; cutting all the triangle surface patches which interact with the virtual sphere with the virtual sphere to obtain a tumor hole; based on the radius of the tumor and vertex information on the tumor hole, conducting longitude and latitude sampling to generate a tumor network composed of the triangle surface patches. According to the invention, the method can add a tumor lesion at any position of the blood vessel digital model, greatly enriches case models available to the field of virtual operation, and is simple to operate and easily handled.

Description

technical field [0001] The invention relates to the technical field of virtual surgery, in particular to a method and device for editing tumor lesions of digital models of blood vessels. Background technique [0002] Virtual surgery is the use of medical imaging data, using virtual reality technology to establish a virtual environment in the computer, so that doctors can use the information in the virtual environment for surgical planning, training, and guiding surgery in actual surgery. The traditional surgical procedure has disadvantages such as high risk, great pain for the patient, and unsatisfactory postoperative effect. The surgical effect is greatly affected by the professional level of the doctor. The use of augmented reality technology allows medical workers to immerse themselves in virtual scenes, perceive and learn various surgical operations through sight, hearing, and touch, and experience and learn how to deal with the actual situation in clinical operations. ...
