Feasibility of radiochromic gels for 3D dosimetry of brachytherapy sources
Popis výsledku v původním jazyce
Two radiochromic gel dosimeters, Fricke-xylenol orange (FXO) gel and Turnbull Blue (TB) gel, were studied in the scope of the iMERA+ project ?Increasing cancer treatment efficacy using 3D brachytherapy? for their feasibility for determination of 3D dosedistributions in brachytherapy. Initially, the dose, dose-rate and energy dependence of the gels was investigated. Subsequently, the gels were irradiated by point low-dose-rate source IsoSeed I25.S16 (125I) and high-dose-rate source GammaMed+ (192Ir) andscanned using an optical computed tomography. Optical transmission images of irradiated gels were processed to obtain optical density maps inside the gels which are proportional to the absorbed dose. With pixel resolution of 0.25 mm the detailed 3D dosedistributions were reconstructed. The radial dose function between 1.5 and 35 mm from the source and anisotropy function at 10 mm radius were determined and compared to Monte Carlo calculations and TG-43 reference data showing a good agr
