Abstract

A 3D/2D vascular registration method includes: according to topological information of vessels in a 3D vascular image, a first vascular image model is obtained, and according to the topological information of vessels in a 2D vascular image, a second vascular image model is obtained; according to the first vascular image model and the second vascular image model, obtain a spatial transformation relationship between the three-dimensional vascular image and the two-dimensional vascular image; wherein, the spatial transformation relationship is used to register the 3D vascular image and the 2D vascular image. The 3D/2D vascular registration method can establish the vascular image model according to the topological information of the vessel in the vascular image model, register according to the vascular image model, so as to give consideration to both high accuracy and high calculation efficiency.
