Increasing organ dose accuracy through voxel phantom organ matching with individual patient anatomy

摘要

Purpose: Given the large use of computed tomography (CT) worldwide, the potential harmful effects and the radiation dose delivered to the patient have become high-interest topics among the scientific community. The main objective of this work was to modify existing three-dimensional (3D) voxel phantom models to resemble real patients as much as possible, thus trying to give a contribute towards the concept of a more personalized patient dosimetry. Moreover, comparisons were made of organ dose computed in the standard reference phantom and phantoms modified to match patient body size and organ size. This study focused essentially on one of the biggest and most radiosensitive organs in the thorax, the lungs.
