Research Abstract

We published a paper regarding basic concept of SOF dosimeter (Scintillator with optical Fiber Dosimeter) as a function of dosimeter. SOF dosimeter measurements were performed for 11 patients who had a high dose rate brachytherapy undergoing to prostate cancer. Measurements were performed at the highest dose point inside the urethra predicted by treatment planning software, the dose given during the treatment was confirmed by real-time monitoring. To adapt high energy X ray or gamma ray measurement, dichroic mirror type SOF dosimeter was developed. We optimized the threshold wavelength of the dichroic mirror. Moreover, we developed 192 channel type SOF dosimeter system.
