JS5-1 Particle therapy: past, present, and future

Abstract

Charged particles such as protons and carbon-ions are known to have physical advantages in radiotherapy for deep-seated tumors because of their desirable dose distributions for the target volume with fewer portals compared with photons, and they can therefore reduce radiation-induced morbidities by reducing irradiated volumes and doses at the surrounding normal tissues, theoretically, but it had been argued that particle therapy was truly effective and more feasible than photon-based radiotherapy.
