Assessment of Radiochromic Gel Dosimeter Based on Turnbull blue dye for Relative Output Factor Measurements in Small Radiosurgery Fields of the Leksell Gamma Knife Perfexion

Original language description

The aim of the study was to perform assessment of radiochromic gel dosimeter based on Turnbull blue dye formed by irradiation for measurement of ROFs for 4 mm and 8 mm collimators for the Leksell Gamma Knife PerfexionTM. All measurements have been carried out using home-made spherical Perspex glass phantom of diameter 160 mm. TB gel dosimeters were scanned using homemade optical CT scanner. The results are compared with vendor recommended Monte Carlo calculated ROFs values of 0.814 and 0.900 for 4 mm and 8 mm collimators, respectively. The comparisons between the gel measurements and the treatment planning system (TPS) calculation are presented in the form of 2D isodoses for the central slices and 1D profile. Calculated ROF 0.874 and 0.746 for 8 mm and4 mm collimator respectively are in good agreement with vendor recommended values and measured relative dose distribution in central slice and measured profiles of all shots show excellent correspondence with TPS.
