Interventional instrument endpoint real-time positioning system, method and device in vascular interventional operation

Abstract

The invention belongs to the crossing field of digital image processing and medical imaging, particularly relates to an interventional instrument endpoint real-time positioning system, method and device in a vascular interventional operation, and aims at solving the problems that an existing interventional instrument endpoint positioning method is poor in positioning real-time performance and accuracy. The system comprises: an image acquisition module configured to acquire an X-ray transmission image containing an interventional guide wire as an input image; and an endpoint positioning moduleconfigured to acquire position information of two endpoints of the interventional guide wire in the input image through a pre-trained guide wire endpoint positioning network. According to the method,the influence of redundant background information in the X-ray transmission image on guide wire endpoint positioning is effectively solved, the guide wire endpoint positioning can be intervened more quickly, and the positioning accuracy is improved.

Description

technical field [0001] The invention belongs to the intersecting field of digital image processing and medical imaging, and in particular relates to a real-time positioning system, method and device for an end point of an interventional instrument in a vascular interventional operation. Background technique [0002] Cardiovascular disease is a common and frequently occurring disease, and it is currently the number one killer that endangers human life and health worldwide. According to the World Health Organization, cardiovascular diseases cause about 17.9 million deaths worldwide each year, accounting for 31% of the total number of deaths. The treatment of cardiovascular diseases mainly includes two types: traditional open surgery and vascular interventional surgery. Because percutaneous coronary intervention has the characteristics of less trauma and rapid postoperative recovery, it has been widely used in the treatment of cardiovascular diseases in recent years.
