Finished my MRIdian treatment in Orlando Cancer Center in February. 5 Treatments with spaceoar. NY Presbyterian/Cornell Weill is doing a 1 treatment vs 5 clinical trial. 2 mm healthy tissue exposure vs 3-6 with Proton. Real time mapping with the built in MRI and dynamic mapping, if needed. Built in MRI is a big deal. It is more accurate than fusing images from other sources. Some urine restriction side effect but all good now. Looked at Proton at first as well. If Proton Therapy had a built in MRI and auto shutoff, I might have leaned in its direction.
