... if you have a reasonably sound foundation in electronic and electrical engineering, have a healthy regard for the safety issues surround high voltages and radiation (and who doesn't?), plus an enquiring mind (the "perpetual student" mindset), then you should do OK (at anything)!
This statement is very belittling to those who work for the manufacturers of medical imaging equipment and spend many weeks (and sometimes months) of their lives on training courses within the factories and training centres, gaining experience in the field along with the backup of the technical support from the head office and factory support personnel.
Modern medical x-ray systems have come a long way in the last 25 years and need detailed knowledge to be able to safety maintain them to the high standards needed.
It may be possible to provide a one or two week course for basic first line service (replacing LBD collimator lamps, checking for trips and fuses and minor mechanical faults) but this will in no way allow the individual to safely service or install a modern system. Even what use to be describe as a basic bucky room has been transformed into a full digital image system with the introduction of flat plate detectors and automatic tube tracking systems. Playing with these without attending the relevant manufactures course and manufactures basic training would be foolhardy and irresponsible.
Most manufactures provide 3rd party training and tailor them for different targeted levels. (Full course or cut down for first line maintenance.) I suggest this is the only path to take for the safety of the patients, operators and equipment (not to mention your own!).
