Abstract

The invention provides a blood vessel tracking method, a coronary artery image segmentation method, a medium and electronic equipment. The blood vessel tracking method comprises the steps of acquiringa seed point from a three-dimensional medical image as a current seed point; processing the three-dimensional medical image by using a convolutional neural network to obtain the direction and radiusof a target blood vessel at the current seed point; if the direction of the target blood vessel at the current seed point meets a termination condition, obtaining the target blood vessel according tothe direction and radius of the target blood vessel at each seed point; and otherwise, acquiring a new seed point from the three-dimensional medical image as the current seed point, and skipping to the step of processing the three-dimensional medical image by using a convolutional neural network. The blood vessel tracking algorithm basically does not need manual participation, and the problems ofcomplexity, time consumption and the like caused by the fact that an existing blood vessel tracking method is achieved manually are solved.

Description

technical field [0001] The invention belongs to the field of image analysis, and relates to a blood vessel tracking method, in particular to a blood vessel tracking method, a coronary image segmentation method, a medium and an electronic device. Background technique [0002] Accurate information about the geometry and topology of a patient's vascular system is crucial for many medical applications, and CT angiography (CTA, CT Angiography) is mostly used in the prior art to obtain this information. CTA is an angiography technology that combines CT enhancement technology with thin-layer, large-scale, and fast scanning technology, and through reasonable post-processing to clearly display the details of blood vessels in various parts of the body. The basic principle of CTA is to rapidly inject the contrast agent into the patient's body through the vein, and use artificial intelligence software to control the contrast agent tracking technology and ECG gating to clearly display th...
