    Purpose: The present study compares the components of out of field dose of two linear accelerators and quantifies (i) the variation of out-of-field dose with the detector, (ii) the phantom scatter, collimator scatter and head leakage contribution towards out-of-field dose for two linear accelerators (LINAC), and (iii) the variation of out-of-field dose with Field Size (FS) Materials and Methods: The out-of-field measurements were obtained from Varian Unique Power Linear Accelerator (VUP) and compared with the Varian Truebeam® STx Linear accelerator (VTB) using PTW chambers of different volumes and slab phantoms. The measurements with different chambers were performed for 10 cm2 ×10 cm2 FS with VUP with collimators 00 and 900 . The out-of-field dose components were measured for a small and intermediate FS for VUP and VTB. The measured results were compared with the .. Read More»
