SYSTEM AND METHOD FOR MULTI-MODALITY SEGMENTATION OF INTERNAL TISSUE WITH LIVE FEEDBACK

摘要

A segmentation system and method include defining (14) a search region by selecting two locations in an image of a structure to be segmented and sampling the search region to provide an unwrapped image. The unwrapped image is edge filtered (20) to determine likely boundary pixels in the image. A directed graph is constructed (22) for the unwrapped image by determining nodes of the graph by computing (24) a lowest cost between boundary pixels. A potential segmentation is generated (26) for user approval using live images. In accordance with a trace by the user, nodes are connected (32) for a final segmentation of the image of the structure to be segmented.
