Abstract

The invention provides a carotid plaque identification method based on cross-modal prediction from CTA to MRA. The method comprises the following steps: a data collection step: paired carotid CTA andMRA image data are collected; plaque segmentation and model training: carotid artery lumens of CTA and MRA are positioned firstly, then carotid artery plaques are segmented, plaque area images of CTAand MRA are obtained, the plaque area images of CTA and MRA are sent to a pix2pix or cycle-GAN network to be trained, and a model obtained after preliminary training is obtained. According to the method, a complete and novel algorithm flow is designed, the carotid artery lumen and plaque on the CTA image are automatically segmented by using an improved deep learning Multiplan-net algorithm, and anoptimized adversarial generative network is designed on the basis to perform CTA data amplification, so that the segmentation precision is further improved.

Description

technical field [0001] The present invention relates to the field of medical image processing, in particular to a carotid plaque recognition method and system for cross-modal prediction from CTA to MRA. In particular, it relates to a carotid plaque recognition algorithm for cross-modal prediction of CTA images into the domain of MRA images. Background technique [0002] Cerebrovascular disease is recognized worldwide as one of the diseases with the highest morbidity and mortality, including hemorrhagic cerebrovascular disease and ischemic cerebrovascular disease. Among them, ischemic cerebrovascular disease accounted for 87% [1] . Since the carotid artery is one of the main arteries supplying blood to the brain, severe atherosclerosis in the carotid artery may lead to cerebral ischemia. The obvious feature of carotid atherosclerosis is the appearance of carotid plaque in the arterial lumen [2] , Plaque composition is different, its vulnerability and stability are also di...
