- Abstract
- In this paper, we report on the development of a scintillation-fiber detection method for close verification in hadron therapy. In order to achieve the position sensitivity required for precision measurement of closes, a detector composed of 1-mm-thick scintillation fibers and a multi-channel photodiode was constructed and tested with 45-MeV proton beams provided by the MC50 proton cyclotron at the Korea Institute of Radiological and Medical Science (KIRAMS). The results of the beam test showed that the spatial resolution of the data determined by using the standard deviation sigma was similar to 1.0 mm, which is sufficiently accurate to verify beam-induced doses in hadron therapy. Furthermore, the quantitative accuracy appearing in the data is on the order of similar to 1%. We expect the detector composed of scintillation fibers and operating in the charge-integration mode to allow us to perform quality measurement of doses in various hadron therapies.
