Abstract:Purpose/Objective:
The purpose of this study is to investigate the effect of treatment couch and immobilization devices on surface dose for megavoltage photon beams.
Material/Methods:
Percentage surface dose (PSD) measurement was carried out in Elekta Synergy™ Linear accelerator using PTW Markus® Parallel plate ionization chamber of volume 0.05cm3 with water equivalent RW3 Slab phantom (PTW, Germany). The measurement depth was considered at 0.07mm. The reference PSD was… Show more
