DUAL LOCALIZATION OF BRACHYTHERAPY RADIOACTIVE SEEDS

摘要

A brachytherapy seed localization system for localizing radioactive seeds within a diseased tissue, the brachytherapy seed localization system employs a tool tracking machine (50) for generating a tracked seed distribution map (51) of delivered locations of the radioactive seeds within the diseased tissue, and a tissue imaging machine (60) for generating a seed distribution image (61) of projected locations of the radioactive seeds within the diseased tissue including at least one false projected location. The brachytherapy seed localization system further employs a brachytherapy seed localizer (70) for generating a composite seed distribution map (71) of estimated locations of the radioactive seeds within the diseased tissue derived from a combination of the tracked seed distribution map (51) and the seed distribution image (61) excluding any false projected location(s) within the seed distribution image (61).
