In this study, a fibre-optic dosemeter (FOD) using an organic scintillator with diameter of 0.5 mm for photon-beam therapy dosimetry was fabricated. The fabricated has many advantages, including water equivalence, high spatial resolution, remote sensing and real-time measurement. scintillating light generated from organic-dosemeter probe embedded in solid-water stack phantom is guided to photomultiplier tube electrometer via 20 m plastic optical fibre. Using FOD, the skin dose percentage...
In this Letter, we demonstrate an easy-to-fabricate time-domain Vernier-effect-based sensor. An all-fiber variable optical delay line (VODL) is utilized to drive OPD scan of two interferometers simultaneously, and fiber Bragg gratings are used filter out slightly detuned interferometric signals. Then normalized interferograms with different spatial frequencies can be achieved generate envelope modulation, viz., a Vernier envelope, enhanced sensitivity in comparison the native state used. The...
To obtain real-time dose information in photon-beam therapy using a clinical linear accelerator, we fabricated novel Cerenkov fiber-optic dosimeter two plastic optical fibers without employing scintillator. In this study, the light intensity and spectrum of radiation induced by high-energy photon beam were measured as functions irradiation angle length difference between probe. Also, obtained percentage depth curve for 6 MV with field size 10 × cm <sup...
A water-equivalent fiber-optic dosimeter was fabricated using an organic scintillator, a plastic optical fiber and photo-multiplier tube for real-time dosimetry in diagnostic radiology. We measured the scintillating lights, which are changed due to exposure parameters, by placed on top of acrylic-aluminum chest phantom provid backscatter medium. The light output signals were compared with entrace surface doses obtained dose-area product meter semiconductor dosimeter.
