Calibration of Gafchromic EBT3 for Dose Measurements in Low-Energy Proton Beam
The use of radiochromic film (RCF) dosimetry is widely consolidated for applications in photon, electron and proton beams. It offers several advantages, in particular, two-dimensional measurements of dose distributions with high spatial resolution, no post irradiation processing required and no daylight sensitivity. In addition, it shows small LET and energy dependence. GAFCHROMIC® EBT3 films, ...
متن کاملCalibration of GafChromic EBT3 for absorbed dose measurements in 5 MeV proton beam and (60)Co γ-rays.
PURPOSE To study EBT3 GafChromic film in low-energy protons, and for comparison purposes, in a reference (60)Co beam in order to use it as a calibrated dosimetry system in the proton irradiation facility under construction within the framework of the Oncological Therapy with Protons (TOP)-Intensity Modulated Proton Linear Accelerator for RadioTherapy (IMPLART) Project at ENEA-Frascati, Italy. ...
متن کاملEnhancement of MD-55-2 radiochromic film sensitivity using a multilayer film technique for applications in the low dose range
ABSTRACTBackgrounds: MD-55-2 is one of the Radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 Gy. However, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.Materials and methods: In this project, the useful range of the film has been extended by using a multilayer film techniqu...
متن کاملDosimetric characterization and use of GAFCHROMIC EBT3 film for IMRT dose verification
Radiochromic film has become an important tool to verify dose distributions in highly conformal radiation therapy such as IMRT. Recently, a new generation of these films, EBT3, has become available. EBT3 has the same composition and thickness of the sensitive layer of the previous EBT2 films, but its symmetric layer configuration allows the user to eliminate side orientation dependence, which i...
متن کاملEvaluation of lens dose from anterior electron beams: comparison of Pinnacle and Gafchromic EBT3 film
Lens dose is a concern during the treatment of facial lesions with anterior electron beams. Lead shielding is routinely employed to reduce lens dose and minimize late complications. The purpose of this work is twofold: 1) to measure dose pro-files under large-area lead shielding at the lens depth for clinical electron energies via film dosimetry; and 2) to assess the accuracy of the Pinnacle tr...
