My personal opinion is that a lot of Medical professionals are simply gatekeeping at this point of time and using legal definitions to keep changing goalposts.
However this is a theme that will keep on repeating in all domains and I do feel that gradual change is better than sudden, disruptive change.
This is a really interesting point that I haven't considered. Namely, regulatory arbitrage is going to yield enormous benefits in the medical AI space. The sheer amount of data needed to train the model requires data centralization the west has no desire to move toward. But if China does crack the nut, it seems like it will necessarily create an upheaval in the west, whether we like it or not.
The other doctors will still be there for you to sue.
Will you be able to source a radioactive source for your x-rays?
DIY radiation therapy would be a whole new level.
Healthcare-grade x-ray tubes are not something you easily can obtain without a license.
It does require a radiologist name on the paperwork as they are the one with the radiation licence. However it is possible to get one if not a radiologist (dentists do, and radiographers have).
Being licensed to use the equipment is the hard bit, as insurance companies require accreditation which is hard to get.
