Intensity modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the tumor without damaging much of the healthy tissue around it. WebbWhat are the difference between photons and protons? The names are very similar — photon versus proton — but there is a world of difference. Photons, or X-Rays, are pure energy and have no mass (although Einstein would disagree as energy does have mass). Protons have energy and are relatively massive and heavy.
