Abstract

The embodiment of the invention provides a method and apparatus for register two-dimensional centerline and three-dimensional centerline of blood vessel. The method includes extracting features of two-dimensional centerline of target blood vessel from two-dimensional image of target blood vessel, extracting feature of three-dimensional centerline of target blood vessel from three-dimensional imageof target blood vessel. Modeling features of the two-dimensional centerline and features of the three-dimensional centerline, acquiring a feature model corresponding to the feature of the two-dimensional centerline and a feature model corresponding to the feature of the three-dimensional centerline, and constructing an objective function according to the feature model corresponding to the featureof the two-dimensional centerline and the feature model corresponding to the feature of the three-dimensional centerline; The objective function is optimized based on a particle swarm optimization algorithm, and the two-dimensional centerline and the three-dimensional centerline are registered according to the optimized objective function. The embodiment of the invention improves the accuracy ofregistration.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of image processing, and more specifically, relate to a method and device for registering two-dimensional centerlines and three-dimensional centerlines of blood vessels. Background technique [0002] Vascular diseases are a serious threat to human health, and related diseases include vascular stenosis, vascular sclerosis, and atherosclerosis. Two-dimensional X-ray (X-ray) contrast images and corresponding three-dimensional CT (Computed Tomography, computerized tomography) contrast images provide details of vascular diseases from different angles. Therefore, the fusion of preoperative 3D CT images and 2D contrast images is extremely important in image-guided minimally invasive vascular surgery. [0003] In order to fuse the 3D CT image and the 2D contrast image of blood vessels, it is first necessary to register the centerline of the blood vessel in the 3D CT image and the centerline of...
