Accuracy of the dose delivery in prostate cancer patients-using an electronic portal imaging device (EPID)
Background: To correct patient positioning errors (setup errors) during prostate cancer treatment using EPID and fiducial gold markers, to improve the accuracy of the dose delivery in these patients. Materials and Methods: Fifteen patients with localized prostate carcinoma after implantation of fiducial gold markers in their prostate gland underwent the five-field IMRT planning technique. The p...

متن کاملPerformance evaluation of gated volumetric modulated arc therapy
Background: Aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (VMAT/RapidArc) using 2D planar dosimetry, DynaLog files and COMPASS 3D dosimetry system. Materials and Methods: Pre-treatment quality assurance of 10 gated VMAT plans was verified using 2D array and COMPASS 3D dosimetry system. Advantage of COMPASS over 2D planar is that it provides the clin...
متن کاملEarly toxicity of moderate hypofractionated volumetric modulated Arc radiotherapy for localized prostate cancer
Background: Based on the radiation biology model of prostate cancer, hypofractionated radiotherapy can improve the treatment outcomes without increasing toxicity. Although hypofractionated radiotherapy is implemented over a short period of time, it is more convenient and cheaper compared with conventional fractionated treatment. The aim of this study was to investigate the early toxicity of mod...
متن کاملComparison between two treatment planning systems for volumetric modulated arc therapy optimization for prostate cancer.
PURPOSE To investigate the performances of two commercial treatment planning systems (TPS) for Volumetric Modulated Arc Therapy (VMAT) optimization regarding prostate cancer. The TPS were compared in terms of dose distributions, treatment delivery parameters and quality control results. MATERIALS AND METHODS For ten patients, two VMAT plans were generated: one with Monaco TPS (Elekta) and one...
