Standardization of knowledge-based volumetric modulated arc therapy planning with a multi-institution model (broad model) to improve prostate cancer treatment quality
Abstract:Purpose: To evaluate whether knowledge-based volumetric modulated arc therapy plans with from a multi-institution model (broad model) are clinically useful and effective as a standardization method.
Methods: A knowledge-based planning (KBP) model was trained with 561 prostate VMAT plans from five institutions with different contouring and planning policies. Five clinical plans at each institution were reoptimized with the broad and single institution model, and the dosimetric parameters and relationship betwee… Show more
