Problems solved by technology
Although the direct editing method can quickly and conveniently generate digital blood vessel models of tumor lesions, this method cannot adapt to blood vessel digital models of different radii, and the transition between the generated tumor and blood vessel digital models is unnatural, which is quite different from real tumors , in addition, the operation process of direct editing will reduce the mesh quality of the blood vessel digital model

The invention relates to a method and a system for generating a tumor in a blood vessel digital model, and electronic equipment. The method comprises the steps of a, selecting a tumor position on a blood vessel digital model; b, calculating the approximate radius of the blood vessel digital model at the tumor position; c, constructing a smooth and regular tumor grid model; d, editing the surface of the tumor grid model, and constructing irregular deformation on the surface of the tumor grid; e, carrying out fairing processing on the joint of the tumor grid model and the blood vessel digital model; f, carrying out strict boundary-preserving grid simplification on the tumor grid model to obtain a generation result of the tumor in the blood vessel digital model. According to the method and the system, the problem that the source of case data is limited does not exist, the method and the system can be used almost without any learning cost, the tumor can be constructed at almost any position in the normal blood vessel digital model, the degree of freedom is high, and the operation is simple and efficient.
Description
technical field [0001] The present application belongs to the technical field of virtual surgery, and in particular relates to a method, system and electronic equipment for generating tumors in digital models of blood vessels. Background technique [0002] Studies have shown that 80% of errors in surgical teaching and training are caused by human factors, so it is extremely important for the training of doctors' surgical skills. Using virtual surgery system to train surgical skills is a new and efficient way. [0003] Virtual surgery system is a typical application of virtual reality technology in the medical field. Virtual surgery is a surgical system that starts from medical image data, uses computer graphics to reconstruct a virtual human soft tissue model, simulates a virtual medical environment, and uses tactile interaction devices to interact with it. Doctors can observe the operation process of experts on the virtual surgery system, and can also practice repeatedly....
