Comparative study of different Al2O3:C dosimeters using OSL technique for dosimetry on Volumetric Modulated Arc Radiotherapy Treatment (VMAT). In: CONGRESSO BRASILEIRO DE FÍSICA MÉDICA, 21., 24-27 de agosto, 2016, Florianópolis, SC. <b>Proceedings...</b> p. 1-5. Disponível em: http://repositorio.ipen.br/handle/123456789/27432.http://repositorio.ipen.br/handle/123456789/27432In modern radiotherapy, the VMAT technique has become a successful treatment alternative. Due to its complexity, a quality assurance program must be established by evaluating, among other items, the dosimetric factors. This paper aims to compare the performance between the OSL aluminum oxide (Al2O3:C) nanoDot™ dosimeters (Inlight™ system) manufactured by Landauer Inc. and TLD-500 Al2O3:C dosimeters manufactured by Rexon™ for VMAT dosimetry using an anthropomorphic phantom. The results showed that both type of Al2O3:C dosimeters presented good repeatability and agreement between the doses measured and calculated by planning system. However, the need of sophisticated readers to OSL analysis of the TLD-500, turns it less practical for routine usage, comparing to Inlight™ system.
