Purpose Proton beam dosimetry using bare plastic optical fibers has emerged as a simple approach to proton beam dosimetry. The source of the signal in this method has been attributed to Cerenkov radiation. The aim of this work was a phenomenological

We experimentally and by means of Monte Carlo simulations investigated the origin of the visible signal responsible for proton therapy dose measurement using bare plastic optical fibers. Experimentally, the fiber optic probe, embedded in tissue-mimic

We investigated the feasibility of proton therapy dosimetry by using bare silica glass optical fibers. A silica glass fiber, with 400μm core diameter, was placed in proton radiation fields generated by a proton therapy cyclotron and simultaneously l

High-density metallic implants can introduce considerable uncertainties in proton therapy treatment planning. These uncertainties eventually translate into proton range errors, which may cause significant underdosing to the target volume or overdosin
