Abstract

Optical imaging detecting Cerenkov-light is a promising approach for molecular imaging or radiation therapy, but it was not yet conducted for proton therapy because light was not thought to be produced with the energy ranges because they are lower than Cerenkov-light threshold. Contrary to this consensus, our research group found that luminescence was emitted from water during proton-beam irradiation. The luminescence images of water phantoms showed clear Bragg peak, and the measured proton ranges from the images were almost the same as those obtained with an ionization chamber. The luminescence was also observed for carbon-ion and low energy X-ray photons.
