Growth kinetics of the EBT3 and EBT-XD films response in radiotherapy beams

摘要

Radiochromic polymer film dosimeters are strong candidates for radiation therapy dosimetry due to high spatialresolution, tissue-equivalency, relative ease of use, and the ability to provide two-dimensional measurement. In thiswork, we studied the growth kinetics of optical density of EBT3 and EBT-XD radiochromic film models, irradiatedusing megavoltage photon and proton therapy beams, over a period of 5 min to 120 hours post-irradiation.
