Abstract Details

2017, Master of Science (MS), Wright State University, Physics.
The determination of a flattening filter free (FFF) beam profile when the collimator is intentionally modified to incorporate a physical wedge. Specifically, radiation beam profiles change shape when a metallic wedge is placed in the path of the beam. Examination of this unknown is necessary to ascertain whether a physical wedge is clinically beneficial for applications involving FFF beams. The aim of this study is to determine if the radiation profile of a flattening filter free beam having a physical wedge is comparable to a beam with a flattening filter, with the same wedge inserted. This research involves measurement of relative dose along the wedged plane. A commercially available particle accelerator was used for this study, which was capable of producing 6 MV bremsstrahlung x-rays. Only beams operating at 6 MV were considered for the investigation. The results indicate that Wedged profiles are similar in many respects when a FFF beam uses the same physical wedge designed for flattening filter beams. Differences in wedged profiles between the FFF and FF beams are discussed.
