Blood vessel registration method, system and device for intravascular aneurysm operation

Abstract

The invention belongs to the field of image data processing, particularly relates to a blood vessel registration method, system and device for an intravascular aneurysm operation, and aims at solvingthe problems that a registration image generated by an existing image registration technology is fuzzy, long in consumed time and much in interference. The method comprises the following steps: converting an acquired CTA image into an aorta blood vessel three-dimensional image, further converting the aorta blood vessel three-dimensional image into an aorta blood vessel two-dimensional image, converting a DSA image into an aorta blood vessel binary image, and obtaining a registered image through a blood vessel registration network based on deep learning, wherein the blood vessel registration network is constructed based on the regression device sub-network, the space transformation sub-network and the re-sampling sub-network. According to the invention, the problem that the DSA image is blurred in the operation can be solved, the abdominal aortic aneurysm position can be found more quickly and accurately in the current X-ray transmission image, and the requirement for assisting a doctorin the intravascular aneurysm repair operation in real time can be met.

Description

technical field [0001] The invention belongs to the field of image data processing, and in particular relates to a blood vessel registration method, system and device for intravascular aneurysm surgery. Background technique [0002] Abdominal aortic aneurysm (AAA) is the most common type of aneurysm. Abdominal aortic aneurysms usually do not cause other symptoms until they rupture, killing 85% to 90% of patients. Clinical studies have shown that endovascular aneurysm repair (EVAR) 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] A key step in endovascular aneurysm repair is for physicians to deliver interventional devices (such as guide wires) to the lesion within a complex interventional channel. Usually, the intervention channel is often ...
