Abstract

The invention discloses a vascular stenosis detection method and device. The method comprises the steps of acquiring a computed tomography angiography (CTA) image for a blood vessel to be detected; straightening and imaging the CTA image at a plurality of set angles to obtain a plurality of straightened images at a plurality of set angles; carrying out width measurement on the straightened imagesone by one, and outputting a width curve corresponding to the straightened image with the set angle; and performing plaque positioning screening on the width curve one by one, and determining a narrowarea of the blood vessel to be detected according to a plaque positioning screening result. By implementing the method and the equipment provided by the invention, the accuracy of vascular stenosis detection can be improved.

Description

technical field [0001] The invention relates to the field of smart medical technology, in particular to a method and equipment for detecting vascular stenosis. Background technique [0002] With the rapid development of social economy, life and health has become a topic of great concern. The medical level and prevention technology of vascular diseases are one of the hotspots, which mainly include atherosclerosis, inflammatory vascular diseases, functional vascular diseases, and true neoplastic diseases of blood vessels. Therefore, automatic detection of vascular morphology has important research value, clinical value and practical significance. In the current detection, the more commonly used method is to use the area method of the blood vessel section to calculate the stenosis rate of the plaque. This is not only very different from the diagnostic habits of medical staff, but also the deviation calculated by the planimetric method is relatively large, and it is difficult ...
