Gafchromic film dosimetry of a new HDR 192Ir brachytherapy source
High-dose-rate (HDR) brachytherapy is a popular modality for treating cancers of the prostate, cervix, endometrium, breast, skin, bronchus, esophagus, and head and neck as well as soft-tissue sarcomas. Because of different source designs and licensing issues, there is a need for specific dosimetry dataset for each HDR source model. The main objective of the present work is to measure 2D relativ...
متن کاملDosimetric characterization of a high dose rate 192I source for brachytherapy application using Monte Carlo simulation and benchmarking with thermoluminescent dosimetry
Background: The purpose of this project was to derive the brachytherapy dosimetric functions described by American Association of Physicists in Medicine (AAPM) TG-43 U1 based on high dose rate 192I sources. Materials and Methods: The method utilized included both simulation of the designed Polymethyl methacrylate (PMMA) phantom using the Monte Carlo of MCNP4C and benchmarking of the simulation ...
متن کاملIndependent assessment of source transit time for the BEBIG SagiNova® high dose rate brachytherapy afterloader
Introduction: The dwell time and transit time components contribute to the overall delivered dose to patients in high dose rate (HDR) brachytherapy treatments. The transit time results from source entry and exit as well as source movements between dwell positions. It depends on various parameters such as the source speed profile, source indexer distance to dwell position, and ...
متن کاملCalibration of iridium-192 source by ionization chamber for high dose rate brachytherapy
Background: The effectiveness and safety of brachytherapy treatment is mainly concerned with the calibration of sources and their traceability to internationally accepted Standards. Secondary Standard Dosimetry Laboratory (SSDL) does not offer calibration of ionization chambers with gamma-ray spectrum of high dose rate source 192Ir . This work has been carried out to calibrate the high dose rat...
متن کاملApplication of a color scanner for 60Co high dose rate brachytherapy dosimetry with EBT radiochromic film
UNLABELLED BACKGROUND.: The aim of this study is to evaluate the performance of a color scanner as a radiochromic film reader in two dimensional dosimetry around a high dose rate brachytherapy source. MATERIALS AND METHODS A Microtek ScanMaker 1000XL film scanner was utilized for the measurement of dose distribution around a high dose rate GZP6 (60)Co brachytherapy source with GafChromic® EBT...
