Abstract: A novel approach for voxel based radiobiological evaluation of the two-phase sequential radiotherapy treatment plans with different dose regimens Aim: To evaluate and compare prostate localization accuracy of Clarity™ 3D ultrasound system compared to on board kV cone beam computed tomography (kV-CBCT) during Prostate radiotherapy and to evaluate absolute Intra-fractional prostate motion from pre-treatment and post treatment 3D ultrasound scan during radiotherapy treatment. Post treatment Clarity 3D USG scan acquired after setting patient on fiducial mark to find out Intra-fraction prostate motion. [Extracted from the article]
