Validation of Biomechanical Deformable Image Registration in the Abdomen Thorax and Pelvis in a Commercial Radiotherapy Treatment Planning System

摘要

PurposeThe accuracy of deformable image registration tools can vary widely between imaging modalities and specific implementations of the same algorithms. A biomechanical model-based algorithm initially developed in-house at an academic institution was translated into a commercial radiotherapy treatment planning system and validated for multiple imaging modalities and anatomic sites.
