> an X-Ray tube is hard to come by I don’t know what energies you need for medical imaging, but a keV linear electron accelerator is commonly called “a CRT”, and it’s already powerful enough to screw you up if you really try. (Of course, the power supply, the flyback converter, and all the other stuff you get at immediately upon opening the case are plenty dangerous even without all the effort it takes to get ionizing radiation out of the tube.)
