Abstract

The invention discloses a transfer learning-based method for establishing an intracranial blood vessel enhanced three-dimensional model. The method comprises the following steps of: acquiring a bright blood image group, a black blood image group and an enhanced black blood image group of an intracranial blood vessel part; performing registration on each bright blood image by using a registration method based on mutual information and an image pyramid by taking the corresponding enhanced black blood image as a reference to obtain a registered bright blood image group; performing empty flow artifact elimination operation on the enhanced black blood images in the enhanced black blood image group by using the registered bright blood image group to obtain an artifact-eliminated enhanced black blood image group; subtracting corresponding images in the artifact elimination enhanced black blood image group and the black blood image group to obtain K contrast enhanced images; establishing a blood three-dimensional model by using the registered bright blood image group and a transfer learning method; establishing a blood vessel three-dimensional model for blood boundary expansion by using the registered bright blood image group; according to the method, the overall state of the intracranial blood vessel is clinically, conveniently, rapidly and visually obtained so as to carry out intracranial vascular lesion analysis.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method for establishing a three-dimensional model of intracranial vessel enhancement based on migration learning. Background technique [0002] According to the latest medical data, vascular diseases have seriously affected the life and health of contemporary people and become one of the diseases with a high mortality rate. Such as atherosclerosis, inflammatory vascular disease, vascular true neoplastic disease and so on. The common causes of vascular diseases are narrowing, blockage, rupture, and plaque in blood vessels. At present, methods based on lumen imaging are usually used to evaluate the degree of vascular disease and vascular stenosis clinically, such as digital subtraction angiography (Digital Subtraction Angiography, DSA), CT angiography (Computed Tomography Angiography, CTA), magnetic Resonance angiography (Magnetic Resonance Angiography, MRA) and high...
