Training scene simulation system and method for minimally invasive cardiovascular interventional operation

Abstract

The invention discloses a training scene simulation system and method for a minimally invasive cardiovascular interventional operation. The system comprises a medical information data storage system, a medical image processing and analytical application system and a medical visualization application system. The medical information data storage system is used for storing human body original medical image information and operation record information. The medical image processing and analytical application system is used for reading the image sequence of a certain selected case, carrying out preprocessing, image segmentation and feature extraction on the read image sequence and outputting the processed image sequence to the medical visualization application system. The medical visualization application system is used for utilizing a volume rendering algorithm for carrying out three-dimensional reconstruction on the information the basis of the image information processed by the medical image processing and analytical application system, therefore, the blood vessel stereoscopic model of a case operation area is obtained, an operating object is provided for operation simulation training, and an operator can obtain real-time position information of medical instruments and the relative positions between the medical instruments and blood vessels.

Description

technical field [0001] The present invention relates to the technical field of computer virtual reality, in particular to a method and system for constructing a simulated training scene for minimally invasive cardiovascular interventional surgery, which provides a visualization part for the virtual training system of minimally invasive cardiovascular interventional surgery. The training object is physicians who will use robots or perform minimally invasive cardiovascular interventional procedures in the traditional way. The invention belongs to the fields of medical equipment technology, computer graphics, virtual reality technology, medical image processing, interventional radiology, surgery and the like. Background technique [0002] Minimally Invasive Surgery (MIS) is an important field of contemporary medicine. With its characteristics of small incision, light trauma, less pain and quick recovery, it provides a safe, reliable and effective medical solution for patients....
