Abstract

The invention discloses an intracranial blood vessel comprehensive image generation method, which comprises the steps of obtaining a plurality of image pairs to be registered of intracranial blood vessels, and preprocessing a bright blood image and an enhanced black blood image in each image pair to obtain a first bright blood image and a first black blood image of the image pair; selecting a partof preprocessed image pairs as test image pairs; performing image registration on the first bright blood image and the first black blood image in each test image pair by adopting a registration method based on mutual information and an image pyramid to obtain a rotation matrix corresponding to the first bright blood image in the test image pair after registration; obtaining the mean value of therotation matrixes of all the test image pairs; utilizing the mean value of the rotation matrix to perform coordinate transformation on the first bright blood images in other preprocessed image pairs except the test image pair, and finishing image registration to obtain a plurality of registered image pairs; and fusing the two images in the registered image pair to obtain an intracranial vessel comprehensive image.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method for generating a comprehensive image of intracranial blood vessels. Background technique [0002] According to research, in 2016, among the 13.7 million new stroke patients worldwide, there were 5.51 million Chinese patients, accounting for as high as 40%. Stroke is commonly referred to as stroke, which is due to blockage or rupture of intracranial blood vessels, which affects the normal circulation of blood, and then causes infarction diseases, such as cerebral hemorrhage, cerebral infarction, etc. If the treatment is not timely, the patient is likely to die; Even with prompt treatment, it can lead to disability for the patient. [0003] At present, methods based on lumen imaging are usually used to evaluate the degree of intracranial vascular lesions and vascular stenosis clinically, such as digital subtraction angiography (Digital Subtraction Angiography, ...
