Abstract
This paper aims to evaluate the performance of the commercial OSL Landauer InLight System to be applied in dosimetric measurements in a Volumetric Modulated Arc (VMAT) brain tumor planning treatment using a Stereotactic End-To-End Verification Phantom Patient (STEEV (TM) - CIRS), comparing its results with CaSO4:Dy TLD pellets manufactured and marketed by the Laboratory of Dosimetric Materials/IPEN, PTW PinPoint (TM) ion chamber and Eclipse 10.0 planning system. The results of commercial InLight (TM) System using the nanoDot dosimeters showed good reproducibility and stability in both laboratory and clinical measurements. The experimental dose values obtained by all dosimetric techniques varied less than +/- 1.0% from prescribed by Eclipse 10.0. The intrinsic precision and uncertainty of the OSL reading device were found fair enough, providing good experimental results for VMAT dosimetry. (C) 2017 Elsevier Ltd. All rights reserved. (AU)
