Investigation of focused Very High Energy Electrons (VHEEs) as a new radiotherapy method
… Electron (VHEE, 50 - 250 MeV) beams focused by a magnetic lens to create a high dose region in a small volume, which is referred to here as a volumetric element. This can be scanned over the radioresistant regions of a tumour at typical depths of deep-seated cancers. Monte Carlo simulations were …
