Dosimetric comparison between XR-RV3 and EBT2 radiochromic film in megavoltage photon beams
Background: Radiochromic film is used for radiation dose measurement, XR-RV3 is used in fluoroscopy and EBT2 film in radiation therapy. The aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. Materials and Methods: Comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...
متن کاملEvaluation of a commercial flatbed document scanner and radiographic film scanner for radiochromic EBT film dosimetry
The purpose of this study was to quantify the performance and assess the utility of two different types of scanners for radiochromic EBT film dosimetry: a commercial flatbed document scanner and a widely used radiographic film scanner. We evaluated the Epson Perfection V700 Photo flatbed scanner and the Vidar VXR Dosimetry Pro Advantage scanner as measurement devices for radiochromic EBT film. ...
متن کاملPost-irradiation colouration of Gafchromic EBT radiochromic film.
Gafchromic EBT (International Specialty Products, NJ, USA), radiochromic film is one of the newest radiation-induced auto-developing x-ray analysis films available for therapeutic radiation dosimetry in radiotherapy applications. Part of any radiochromic film product which undergoes a polymerization reaction for automatic darkening is an associated post-irradiation colouration whereby the film ...
متن کاملMeasuring solar UV radiation with EBT radiochromic film.
Ultraviolet radiation dosimetry has been performed with the use of a radiochromic film dosimeter called Gafchromic EBT for solar radiation exposure. The film changes from a clear colour to blue colour when exposed to ultraviolet radiation and results have shown that the colour change is reproducible within ±10% at 5 kJ m(-2) UV exposure under various conditions of solar radiation. Parameters te...
متن کاملComparison of EBT and EBT3 RadioChromic Film Usage in Parotid Cancer Radiotherapy
Background: EBT and EBT3 radioChromic films have been used in radiotherapy dosimetry for years.Objective: The aim of the current study is to compare EBT and EBT3 radioChromic films in dosimetry of radiotherapy fields for treatment of parotid cancer.Methods: Calibrations of EBT and EBT3 films were performed with identical setups using a 6 MV photon beam of a Siemens Primus linac. Skin dose was m...
