A method for generating intensity‐modulated radiation therapy fields for small animal irradiators utilizing 3D‐printed compensator molds

Purpose The purpose of this study was to investigate the feasibility of using fused deposition modeling (FDM) three‐dimensional (3D) printer to generate radiation compensators for high‐resolution (~1 mm) intensity‐modulated radiation therapy (IMRT) for small animal radiation treatment. We propose a novel method incorporating 3D‐printed compensator molds filled with NaI powder. Methods The inverse planning module of the computational environment...
