Measuring and Assessing the Effect of a Carbon Fiber Couch on Radiotherapy Dose Distribution

Abstract

A vital device for administering radiotherapy, especially intensity-modulated radiation treatment (IMRT) is the Central Opening Carbon-Fiber Couch. There doesn't seem to be any evidence in the literature about the impact of the thickest section (edge couch) on the dose distribution, even though multiple tests were conducted with the radiation field incident on the center of the couch. In this study, we evaluated and improved the computed beam profile doses for the under-couch fields for various field sizes for energy 6MV to reduce the skin surface dosage
