Feasibility of out-of-field dosimetry in photon, proton, and neutron therapies using a 3D-printed patient-specific phantom Public Deposited
Purpose: To test the feasibility of using a three-dimensional (3D) printed patient-specific phantom for out-of-field dosimetry. Conclusion: We found that pencil beam scanning proton therapy offered the lowest out-of-field absorbed dose in comparison to 6 MV and 6 FFF photons and neutron modalities for intracranial fields. The study demonstrated the feasibility of using an inexpensive 3D-printed patient-specific anthropomorphic phantom for out-of-field dosimetry. This is particularly important for quantifying the dose in organs, tissues, and electronics at risk for debilitating radiogenic effects.
