I understand that Lee Health in Ft. Myers (near me) is also down, on a new Mridian machine that just went online last year. They're trying to hire engineers and other experts to service the machine directly and get it working again. They told me they were probably a year out.

I know Elekta has a MRI guided machine similar to the ViewRay Mridian, the Elekta Unity, but somewhat limited to locations here in the states. I know the University of Florida in Jacksonville just brought one of these machines online: https://ufhealth.org/news/2022/uf-health-unveils-imaging-machine-one-42-world-tackle-difficult-cancers. So I suppose I could choose protons or photons at UF Health in Jacksonville with my traditional Medicare, but I'm going with Protons for less extraneous radiation exposure. Moffitt in Tampa is building a proton treatment center, but it won't be online until 2026.

The thing is, with traditional Medicare, you can just call the treatment center you are interested in and inquire if they accept your insurance and go from there.
