Lateral and Distal Dose of Proton and Carbon Ion Beams for Tumor Cells Using PHITS Simulation Code Myat Kay Khaing Nyein Wint Lwin With the development of particle accelerator design and related accessories, the popularity of charged particle therapy has increased. Most commonly used ions for particle therapy are proton and carbon. In terms of dose distribution and relative biological effectiveness (RBE) value, carbon ion is more favorable for deep-seated radioresistant tumor cells. Moreover, it has small lateral scattering compared with proton. But due to the probability of fragmentation itself, fragmented particles travel beyond targeted volume and deposit energy in normal healthy tissues. Although carbon ion shows fragmentation as drawback, better local control of energy is observed in compared with proton. 2020-05-30 http://hdl.handle.net/20.500.12678/0000005882 https://meral.edu.mm/records/5882
