Energy and Dose Rate Dependence of BANG-2 Polymer-Gel Dosimeter

Popis výsledku v původním jazyce

The purpose of this study was to evaluate dependence of BANG-2 polymer-gel dosimeter sensitivity on different photon and electron energies as well as on different mean dose rates expressed as repetition rates for standard clinically used linear accelerator. The sensitivity of dosimeter was represented by the slope of calibration curve in the linear region measured for each modality. Calibration curve (in the linear region) based on five dosimeters (four irradiated and one background) was obtained for each photon and electron energy and different repetition rates. Dosimeter sensitivity dependence on energy was studied for 4, 6 and 18 MV X ray photons and for nominal electron energies 9, 12, 16, 20 MeV. Dosimeter sensitivity dependence on mean dose ratewas separately studied for electron and photon beams with the use of repetition rates 80, 160, 240, 320, 400 MU.min-1. Evaluation of dosimeters was performed on Siemens MAGNETOM EXPERT 1T scanner in the head coil. Multi-echo sequence wit.
