The purpose of this study is to investigate the use of ultra-low, anti-inflammatory doses of radiation therapy (RT) for the treatment of Parkinson's Disease (PD). In this study, the TrueBeam LINAC utilizes a linear accelerator (LINAC) for the delivery of radiation therapy. Dynamic conformal arc (DCA) therapy will be used to deliver a total of five (5) once-a-day radiation treatments (RT) using DaT-SPECT (Dopamine Transporter-Single-Photon Emission Computed Tomography) and MRI imaging to guide radiation treatment planning.
