Method, system and device for detecting interventional instrument in intravascular aneurysm repair operation

Abstract

The invention belongs to the technical field of image processing, particularly relates to a method for detecting an interventional instrument in an intravascular aneurysm repair operation, and aims tosolve the problem that the interventional instrument in an X-ray transmission image in the intravascular aneurysm repair operation cannot be accurately segmented and tracked in real time. The methodcomprises the following steps: taking an X-ray transmission image of a region containing an interventional instrument as a to-be-detected image; generating a binary segmentation mask of the interventional instrument through the trained fast attention network; and covering the binary segmentation mask on the to-be-detected image to obtain an image of the interventional instrument. According to themethod, the problem that the number of foreground pixels and the number of background pixels are extremely unbalanced and the problem of wrong classification of images are solved, the speed and accuracy of X-ray transmission image recognition on segmentation of surgical interventional instruments and image tracking in the prior art are improved, and the requirement for assisting doctors in endovascular aneurysm repair surgery in real time can be met.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an interventional device detection method, system and device for intravascular aneurysm repair surgery. Background technique [0002] Abdominal aortic aneurysm (AAA) is the most common type of aneurysm. Abdominal aortic aneurysms usually cause no other symptoms until they rupture, so rupture of an abdominal aortic aneurysm kills 85% to 90% of patients. Clinical studies have shown that endovascular aneurysm repair (EVAR, Endovascular aneurysm repair) can effectively reduce the morbidity and mortality of patients in the perioperative period. At the same time, the development of science and technology in recent years has also made endovascular aneurysm repair an option for most patients to treat abdominal aortic aneurysms. [0003] The key step in endovascular aneurysm repair is that doctors deliver interventional devices (eg, interventional devices) to the le...
