Abstract

Embodiments of the invention provide an image processing method and a medical imaging device, which are applied to the technical field of image processing and improve the accuracy of recognizing images of left and right coronary arteries to some extent. The image processing method provided in the embodiment of the invention includes the steps of acquiring an original blood vessel three-dimensionalscan image; processing the original blood vessel three-dimensional scan image to obtain a designated blood vessel candidate region; processing the designated blood vessel candidate region to obtain acenter line of the designated blood vessel candidate region; acquiring, along a direction of the center line, two-dimensional slice data perpendicular to the center line at each sampling point on thecenter line; inputting the two-dimensional slice data to a trained neural network for learning and obtaining learning results; and determining a designated blood vessel image based on the plurality of learning results.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing method and medical imaging equipment. Background technique [0002] In recent years, the morbidity and mortality of cardiovascular diseases are increasing year by year, and have become the main cause of death worldwide. Among various cardiovascular diseases, coronary artery disease accounts for a very high proportion of mortality. With the development of technology, CTA (computed tomography angiography, angiography) can be used to make a good diagnosis of heart disease caused by coronary artery. [0003] The coronary arteries include the left coronary artery and the right coronary artery, which respectively emanate from the aorta at the bottom of the heart, extend toward the apex of the heart, and wrap around the surface of the heart. The complex structure of the arteries, and the coronary arteries wrapping the pericardium, makes it a very critical s...
