Radiotherapy with or without mitomycin c in the treatment of locally advanced head and neck cancer: results of the IAEA multicentre randomised trial

, 2003
Background and purpose: Single agent mitomycin c (MMC) has been shown to improve the outcome of radiotherapy in single institution trials. In order to confirm these findings in a broader worldwide setting, the International Atomic Energy Agency (IAEA ...

A novel approach with quadrupole magnets for precise deflection, scattering and focusing of very high energy electron beams (VHEE)

Nuclear Analysis
A novel approach involving quadrupole magnets has been proposed to deflect and disperse electrons in the irradiation fields, as well as a system for focusing beams at specific depths. This research also presents a comparison between VHEE and conventional
