Measurement of Prostate Inter-Fraction Movement by Tracking Implanted Fiducials in Daily CBCT Projections

To develop a method for accurately determining implanted fiducial locations in 3D using template matching and sequential stereo in CBCT projection data. This technique will be used in both retrospective studies to improve motion models and to improve fiducial tracking during treatment for motion management. During planning each fiducial is contoured individually. Using non-clinical research software, a separate template is generated from the...
