Embodiment Construction

[0029] The vascular stent positioning and preoperative selection method of the present invention uses the existing angiography technology to perform digital angiography on diseased blood vessels, so that the blood vessel images are presented on the display of the vascular stent positioning and selection system of the present invention. Afterwards, select a segment of stenotic blood vessel (multiple segments can also be selected at the same time), and define two reference points on each diseased blood vessel (one is the starting point, the other is the end point, and the line connecting the two points indicates the direction of the blood vessel - the reference direction) , to determine the positions of both ends of the stenotic vessel. According to the position of both ends of the blood vessel, search for adjacent points from the starting point along the reference direction and compare with the starting point. If the difference in both numerical and spatial parameters meets the ...

Abstract

A method for selecting and locating the blood vessel scaffold includes choosing at least one narrow segment of blood vessel, determing the positions of its both ends, extracting its narrow data, marking its profile, extracting its profile data, automatically drawing the profile of normal blood vessel according to the positions of its both ends, extracting its profile data, comparing the narrow data with the normal data, calculating the data about scaffold, and regualting and determing the position and length of scaffold. Its system is also disclosed.

Description

technical field [0001] The invention relates to a method for analyzing and obtaining stent parameters commonly used in the field of interventional medicine, in particular to a method for automatic positioning and preoperative selection of vascular stents. Background technique [0002] Vascular stenosis is one of the common diseases in medicine. It can occur in different parts and organs of the human body, including the heart and great vessels, as well as peripheral blood vessels (inferior vena cava stenosis, renal artery stenosis, iliac artery and femoral artery stenosis, etc.) . There are many reasons that can cause vascular stenosis, such as atherosclerosis, abnormal fibromuscular development, polyarteritis, etc. Among them, the lesions of the heart, large blood vessels and cerebrovascular diseases have the most significant impact on human body functions. [0003] With the continuous improvement of the treatment technology for vascular stenosis, a new diagnosis and treatm...
