Two-dimensional medical structure segmentation method, involves selecting structure of image data and initializing rays to form curve based on speed function to segment structure when all rays join on their boundary

摘要

The method involves receiving and visualizing two-dimensional (2D) image data on a display device. A structure in the image data is selected by placing a seed in it. A set of rays from the seed is initialized to form a curve and their speed function is determined. A curve is evolved by propagating the rays based on the speed function. The structure is segmented when all the rays converge on the structures boundary. An Independent claim is also included for a system for segmenting structures from 2D images.
