Abstract
A technique for detecting implanted seeds automatically from CT image data. Various features of the inventive technique include (1) thresholding a 3D CT data set on a voxel basis; and (2) using the Hough transform to identify shapes within the thresholded data that match a predefined 3D shape corresponding to an implanted seed.
