Tissue-equivalent phantoms are suitable tools for radiation dosimetry investigations. The goal of this study was to determine the scattered dose in a simple phantom model mouse with xenographic tumour using experimental measurements and Monte-Carlo calculations. We manufactured cubic polymethyl methacrylate (PMMA) an extrusion on its side both normal tissue xenograft tumour-bearing mouse. posit...

This work investigated the suitability of passive dosimeters for reference dosimetry in small fields with acceptable accuracy. Absorbed dose to water rate was determined in nine small radiation fields with diameters between 4 and 35 mm in a Leksell Gamma Knife (LGK) and a modified linear accelerator (linac) for stereotactic radiosurgery treatments. Measurements were made using Gafchromic film (...

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...
