Embodiment Construction

[0035] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, the geodesic-based cerebrovascular length and tortuosity measurement method provided by the present invention is specifically described, including a data acquisition step 1 and a structure measurement step 2, and the data acquisition step 1 includes:

[0037] Segmentation of cerebrovascular images: perform multi-angle maximum density projection on the image data of the cerebrovascular, and record the voxel spatial position with the maximum density value during projection; then use the phase field model to perform vascular Pixel extraction; then back-project the obtained blood vessel pixel points to the corresponding blood vessel voxel space coordinate position in the volume data, and keep the blood vessel voxels in the volume data as much as possible; finally draw the three-dimensional structure of...

Abstract

The invention relates to the technical field of quantitative analysis of cerebral blood vessels, in particular to a method for measuring the length and curvature of cerebral blood vessels based on geodesics. The geodesic-based cerebral vessel length and curvature measurement method provided by the present invention extracts the cerebral vessel region from the image data, reconstructs the surface structure of the cerebral vessel, classifies the cerebral vessel network according to the connectivity of the cerebral vessel, and marks each The two end points of the blood vessel are calculated, and the geodesic distance, normal curvature and geodesic torsion information of the blood vessel segment between the two end points are calculated. The invention measures the length of cerebral blood vessels based on geodesic distance, which can better reflect the topological structure of cerebral blood vessels in three-dimensional space and truly reflect the degree of curvature and morphological structure of cerebral blood vessels itself, and realize more accurate measurement of the length and curvature of cerebral blood vessels. The metric further reflects the characteristic that the metric only focuses on the cerebrovascular itself and does not depend on the spatial coordinates. It has important application value in the fields of medical image processing, computational geometry, and computer graphics.

Description

technical field [0001] The invention relates to the technical field of quantitative analysis of cerebral blood vessels, in particular to a method for measuring the length and curvature of cerebral blood vessels based on geodesics. Background technique [0002] In the prior art, the shape of blood vessels is the most characteristic biological feature in the human brain circulatory system, and the diagnosis of cerebrovascular diseases based on the changes in the shape and structure of cerebral blood vessels is a typical application project for the diagnosis of vascular diseases. The calculation of the traditional vascular quantitative analysis indicators is carried out in the Euclidean space, and the calculation of the data is strongly dependent on the three-dimensional space coordinate system. In addition, for the convenience of calculation, most of the existing quantitative analysis of vascular morphology first divides the entire vascular network into small segments or parts...
