System, method and device for real-time positioning of interventional instrument endpoints in vascular interventional surgery

Abstract

The invention belongs to the intersection field of digital image processing and medical imaging, and specifically relates to a real-time positioning system, method and device for an end point of an interventional device in a vascular interventional operation, aiming at solving the real-time and accuracy of the positioning method for an end point of an interventional device Poor question. The system includes: an image acquisition module configured to obtain an X-ray transmission image containing an interventional guide wire as an input image; an endpoint positioning module configured to obtain two points of the interventional guide wire in the input image through a pre-trained guide wire endpoint positioning network The location information of the endpoint. The invention effectively solves the influence of redundant background information in the X-ray transmission image on the positioning of the guide wire end point, realizes relatively fast positioning of the intervention guide wire end point, and improves the positioning accuracy.

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. The World Health Organization pointed out that cardiovascular diseases cause about 17.9 million deaths worldwide every 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.
