Measurement of Radiation Dose Emitted by 4 x 4 cm2 and 10 x 10 cm2 Aperture of Linear Accelerator

Abstract

The amount of the beam emitted from linear accelerators can be adjusted by changing the jaw intervals of multi leaf collimator (MLC) system. The area to which the beam will be delivered is determined. In this study, the jaw intervals of linear accelerator in the Oncology unit of the Tokat Gaziosmanpaşa University Faculty of Medicine have been determined as 4 x 4 cm2 and 10 x 10 cm2 and the radiation dose emitted for both conditions has measured. The results have compared with other studies in the literature.
