| 内容記述 | In order to measure the three-dimensional dose distribution in X-ray radiotherapy, we developed a plate-type thermoluminescence dosimeter (TLD) using the TL phosphor Li3B7O12:Cu, which has Z eff = 7.42 and a density of 1.01 gcm-3. This detector was expected on useful application in advanced X-ray radiotherapies such as intensity-modulated ratiation therapy (IMRT) etc., because it can obtain 3D dose measurements simply and quickly with a single exposure. In this paper, we report the response of this plate-type TLD to a therapeutic carbon beam at the Heavy Ion Medical Accelerator in Chiba (HIMAC). Using a plate heater and charge coupled device (CCD) camera, we captured thermoluminescence images of plate-type TLDs irradiated by a therapeutic carbon beam. The TL intensity was measured at each water equivalent depth and compared with output of the ionization chamber. The relative TL efficiency of this TLD as 60Co gamma-ray equivalent decreased gradually with increasing dose-averaged linear-energy-transfer (LET), reaching about 20% at the Bragg peak of 290 MeV/u carbon ions. | |||||
