Description
Summary:In this study, a fiber-optic radiation sensor with an organic scintillator is fabricated to measure high-energy photon beam from a clinical linear accelerator (CLINAC) and a fiberoptic sensor array is also fabricated to measure two-dimensional, high-resolution and real-time dose distributions for small field radiotherapy dosimetry. The scintillating lights generated from each organic sensor probe embedded and arrayed in a water phantom are guided by 10 m plastic optical fibers to the light- measuring device. The two-dimensional photon beam distributions in a water phantom are measured with different energies and field sizes of photon beams. Also, percent depth dose curves for 6 and 15 MV photon beams are obtained.
