Automatic detection of radioactive seeds for CT based post-planning for prostate seed implantation based on the hough transform

摘要

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.
