Energy Dependence of the New Gafchromic EBT3 Film:Dose Response Curves for 50 KV, 6 and 15 MV X-Ray Beams
Purpose: To study and compare the dose response curves of the new GafChromic EBT3 film for megavoltage and kilovoltage x-ray beams, with different spatial resolutions. Methods: EBT3 films (lot#A101711-02) were exposed to each x-ray beam (6 MV, 15 MV, and 50 kV) at 7 dose values (50 3200 cGy). Each film piece was scanned three consecutive times in the center of Epson 10000XL flatbed scanner in 4...
متن کاملEnergy response of EBT3 radiochromic films: implications for dosimetry in kilovoltage range
The objective of this study is to evaluate the suitability of recently introduced radiochromic film EBT3 for clinical dosimetry in the kilovoltage (kV) range. For this purpose, a kV X-ray irradiator, X RAD 320ix in the range 70 to 300 kVp, a clinical 60Co source, a 6 MV and an 18 MV X-ray clinical beam from a Varian linear accelerator were calibrated following AAPM dosimetry protocols. EBT3 fil...
متن کاملDose-response curve of EBT, EBT2, and EBT3 radiochromic films to synchrotron-produced monochromatic x-ray beams.
PURPOSE This work investigates the dose-response curves of GAFCHROMIC(®) EBT, EBT2, and EBT3 radiochromic films using synchrotron-produced monochromatic x-ray beams. EBT2 film is being utilized for dose verification in photoactivated Auger electron therapy at the Louisiana State University Center for Advanced Microstructures and Devices (CAMD) synchrotron facility. METHODS Monochromatic beams...
متن کاملEntrance surface dose measurements for routine X-ray examinations in Chaharmahal and Bakhtiari hospitals
Background: There is not any report on the radiation doses received by patients in diagnostic radiology sections in hospitals under control of Chaharmahal and Bakhtiari Medical Sciences University, in the south west of Iran. Objectives: The aim of this study is measurement of entrance surface doses (ESD) for the most routine types of X-ray procedures in radiology centers as part of ongoing d...
متن کاملSU-E-T-90: Investigation of Different Bleaching Wavelengths on the Absorbed-Dose Sensitivity of NanoDot OSLDs Exposed to 6 MV X-Ray Beams.
PURPOSE To determine the effect of different bleaching wavelengths on the luminescence response of Al2 O3 :C optically stimulated luminescence detectors (OSLDs) exposed to accumulated doses of 6 MV photon beams. METHODS OSLDs of the nanoDot type were used and readout with a microStar InLight reader. To determine the effect of different bleaching wavelengths on the luminescence response of nan...
