SU-E-T-535: On the Out-Of-Field-Doses Caused by Secondary Particles From Light Ion Beams in Charged Particle Therapy

Purpose: Charged ion therapy in the United States consists mainly of proton therapy, which may deposit a larger than necessary lateral dose to healthy tissues. Application of heavier particles may Result in an improvement, i.e., lowering the dose bath to the patient. The purpose of this study is to evaluate the secondary halo dose of therapeutic light ion beams. Methods: Monte Carlo simulations have been performed to evaluate lateral dose...
