A method for simulation of cardiovascular disease

Abstract

The present invention discloses a method of simulation simulation of cardiovascular lesions, involving the field of medical virtual reality, including the following steps: collecting three -dimensional space location data for blood vessels; rendering the connection of vascular direction, at the same time, based on geometric shafts to display different shapes and different shapes and different shapes and different shapes andThicking blood vessel lines; calculate the transition point distribution between the folding line segments to obtain a smooth vascular display result; perform parameter modeling of the lesion position, based on the model and combined with the vascular display result, and finally display the blood vessels corresponding to the real lesion.shape.This technical scheme can show the real heart disease position and the display relationship between the corresponding blood vessels in the real -time environment. It is more accurate to simulate the actual situation of intervention surgery, improve the authenticity of doctors training and preview; realize various typesIn the case of diseased, different lesions have the effects of vascular deformation, realizing personalized configuration and adjustment, and increasing diversity in the simulation process.

Description

technical field [0001] The invention relates to the technical field of medical virtual reality, in particular to a method for simulating cardiovascular disease. Background technique [0002] Cardiovascular disease is currently one of the leading causes of death. Among them, the lesions in the coronary arteries of the heart are the most serious cause of death. Usually, cardiovascular diseases mainly form plaques in the coronary arteries, and this is an important reason that seriously affects human health. An effective technique for the treatment of cardiovascular diseases is percutaneous coronary intervention. The main process of percutaneous coronary intervention is: under the guidance of X-rays, the doctor uses a guide wire to pass through the blood vessels on the body surface and send it into the human thigh Artery, the guide wire passes through the femoral artery, enters the aorta retrogradely along the artery, and enters the coronary artery vascular network. Then the do...

Problems solved by technology

[0003] Although the above operation is a minimally invasive operation, the specific operation is very complicated due to the movement of the guide wire inside the blood vessel.

Under normal circumstances, surgical operators are required to have superb skills and rich clinical experience. However, it is difficult to implement training and teaching to improve doctors' skills. One important reason is the lack of actual operation experiments, and the patient's life cannot be used for Experimental trial and error, in this case, in order to train doctors' skills and rehearse and plan the operation process, some vascular interventional simulators specially used for simulation training came into being

[0004] In summary, although the vascular interventional simulators in the prior art can train doctors and / or medical students' surgical skills and rehearse and plan the surgical process, due to the different vascular structures and lesion locations between different patients There are differences, how to effectively improve the accuracy of the simulation process for skin coronary intervention, and the technical issues such as the authenticity of virtual training and rehearsal, are the problems that those skilled in the art need to solve
