Hepatic tumor comprehensive surgical planning analogy method and system thereof based on three-dimensional multimode images

Abstract

The invention discloses a hepatic tumor comprehensive surgical planning analogy method and a system thereof based on three-dimensional multimode images. The method comprises the steps that firstly, a data base containing the data of an object is constructed; secondly, three-dimensional registration and fusion are conducted on the medical images, having different modes or single mode and differentperiods, of the object; thirdly, a specific tissue is divided by the automatic and semi-automatic modes, and the three-dimensional modeling of important tissues in and around the liver is realized bythe three-dimensional reconstruction technology so as to reconstruct an abdominal three-dimensional model having the immersion and interaction features; fourthly, before-simulation comprehensive riskanalysis is conducted based on the modeling result, referred to the practice guidelines and combined with the object information; and finally, all kinds of simulation surgical plans are designed according to the result of the comprehensive risk analysis, surgical simulation with strong sense of reality is conducted, a surgical route is planned, and risk and prognosis analysis is conducted on the planning simulation result. Through repeated surgical simulations, the surgical skills and the mastery of a user can be improved, and medical teaching can be conducted through the method and the system.

Description

technical field [0001] The invention belongs to the field of medical image processing and application, and in particular relates to a method and system for planning and simulating comprehensive surgery for liver tumors based on three-dimensional multi-mode images. The present invention can effectively model the relevant tissues of the subject's abdomen, visually display the virtual environment of the subject's abdomen, perform comprehensive risk analysis before the simulated operation, plan and simulate the comprehensive operation plan, and perform risk and prognosis analysis on the simulation results. Background technique [0002] Liver cancer is a global disease that seriously threatens the life and health of the world and people in our country. Its diagnosis and treatment are hot and difficult issues in medical research in my country today. The combination of modern medical diagnosis and treatment methods and computer technology can accurately analyze liver tumors, perfor...

Problems solved by technology

[0004] The above studies only considered a single imaging mode (CT imaging), which is difficult to accurately reflect the actual situation of liver tumors, and only for certain aspects of surgical planning simulation (mainly liver tumor resection), and in the realization of virtual cutting It also mainly adopts the regular liver resection technology based on liver lobes and liver segments. The preoperative comprehensive analysis, surgical planning and simulation research of common comprehensive treatment methods are seldom involved. Combined Analysis of Prognosis
