Quantitative Assessment of the Visibility of Fiducial Makers in Prostate by Monte Carlo Simulation of On-Board kV Imaging System

Y. Chen, J. O'Connell, Chr. Ko & J. McDonough
Background: Accurate target positioning and motion tracking of the prostate gland is critical for precise delivery of radiation treatment for prostate cancer patients. Gold seeds have been used for successful real-time target tracking using simultaneous kV-MV imaging in radiation therapy. Implanted [for full text, please go to the a.m. URL]
