Virtual electron energies dosimetry of a medical linear accelerator

Abstract

The aim of this study was to compare dosimetric characteristics of the virtual energies determined by the film dosimetry and treatment planning computer. METHODS GafChromic EBT films is placed perpendicular to solid water phantom irradiated with two different electron energies. Dosimetry of virtual energies were evaluated by PTW Mephysto mc 2 Verisoft software program. RESULTS The comparison of treatment planning computer and dosimetric data of the virtual energies showed that they were compatable with each other. CONCLUSION In conclusion; it is recommended that one should use the virtual energies after the determination of the dosimetric characteristics.
