In this study, we have fabricated a scintillating fiber-optic dosimeter (SFOD) for a Co-60 radiotherapy dosimetry. The ??-rays generated from a Co-60 machine are measured using a SFOD and percent depth dose (PDD) curves are obtained according to the different depths of water phantom. Also, Cerenkov lights generated by the interactions of primary or secondary electrons and a plastic optical fiber are...
In this study, we have developed a non-contact temperature sensor using a silver halide optical fiber for medical endoscopic usage. We have measured an infrared radiation which is transferred by a silver halide optical fiber from a heat source using a thermal optical power-meter and a thermopile sensor. To increase the amount of infrared radiation through the silver halide optical fiber and to the...
Usually, two kinds of light signals such as scintillating and Cerenkov light are generated in a fiber-optic dosimeter when a high energy electron beam is irradiated. The objectives of this study are to measure, characterize and remove a Cerenkov light generated in a scintillating fiber-optic dosimeter. The intensity of Cerenkov light is measured and characterized as a function of incident angle of...
In this study, we fabricated a fiber-optic radiation sensor with an organic scintillator to measure the high-energy photon beam from a clinical linear accelerator, and a two-dimensional fiber-optic sensor array to measure 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...
