Abstract

Anthropomorphic three-dimensional (3D) dosimeters can be useful for verification of radiotherapy delivery. The aim of this study was to develop a 3D-printing-based method for creating anthropomorphic 3D dosimeters. Internal structures were created using water dissolvable 3D prints as negatives. External structures were 3D-printed, and a mould was produced using silicone rubber. Realistic liver and trachea dosimeters with both internal and external anthropomorphism were produced and subsequently irradiated with photons and protons. A 3%/3 mm gamma analysis resulted in 87% and 86% pass rates. The limiting factor to the resolution of the dosimeters was the 3D prints detail.
