Device for Depth-Dose Distribution Measurement of a Medical Proton Beam in Radiotherapy

摘要

A medico-technical system for hadron radiotherapy of cancer patients based on a 660-MeV proton phasotron was constructed. It is now used at the Joint Institute for Nuclear Research (Dubna, Russia). Upgrade of methods, hardware, and software for radiotherapy is one of the main tasks for further improvement of the system. This work considers the construction of a device for measurement of proton beam depth-dose curve in a treatment room, which is very important for conformal proton beam therapy and dynamic irradiation of a deeply lying target.
