Abstract

The invention relates to a system for detecting plaques in blood vessels, comprising a blood vessel feature model learning unit, a ROI image capture unit, and an abnormal image generation unit. The blood vessel feature model learning unit is used for constructing a blood vessel feature model based on a first set of sample images including a plurality of normal blood vessel sample images. The ROI image capture unit is used for capturing the ROI of a blood vessel image to be detected. The abnormal image generation unit is used for comparing the difference between the ROI of the blood vessel image to be detected and the blood vessel feature model and generating an abnormal image according to a difference result obtained from comparison. The invention further relates to a method for detecting plaques in blood vessels.

Description

technical field [0001] The present invention relates to a blood vessel detection system and method, in particular to a detection system and method for detecting plaque in a carotid artery. Background technique [0002] Carotid artery blood vessels are scanned by ultrasonic diagnosis to determine whether there is plaque on the inner wall of the blood vessel, so as to preliminarily diagnose the risk level of the patient suffering from cardiovascular and cerebrovascular diseases. Traditionally, the method of ultrasound scanning of carotid arteries is B-mode ultrasound (commonly known as B-ultrasound) diagnosis. [0003] However, for the B-mode ultrasound diagnosis method, since the difference in echo intensity between the inner wall tissue of the blood vessel and the plaque tissue is very small, the difference between the two in the ultrasound image is not very obvious, so sometimes Observing ultrasound images with human eyes may cause misjudgment, which may only be judged by ...
