Abstract
Methods, systems, and apparatus including computer programs encoded on a computer storage medium, for rendering an expanded lumen image are disclosed. The methods include extracting a center line of a lumen from a three-dimensional lumen image and obtaining a plurality of viewpoints by sampling the center line, establishing a spherical projection plane for each of the viewpoints, a point on the spherical projection plane corresponding to a point on an inner wall of the lumen, determining a relationship between a two-dimensional projection plane and the inner wall of the lumen according to a corresponding relationship between the spherical projection plane and the two-dimensional projection plane, and obtaining a two-dimensional expanded image of the three-dimensional lumen image by performing image rendering on the two-dimensional projection plane according to the determined relationship between the two-dimensional projection plane and the inner wall of the lumen.
