Interesting radio Mike and a great family story to go along with it.
We used to market a 'low cost' small CT Scanner that used a small Telefunken x-ray tube. I installed one in a small truck for a crazy doc in Louisville years ago. Instead of buying the proper chiller for the x-ray tube he modified a water fountain
. They could only do about 10 scans before the temperature sensor shut down the high voltage. He ran that darn thing all over Kentucky and Indiana. One time the driver figured out how to jumper the temperature sensor and the tube got so hot it melted the brass insert and almost dripped on a patients face 
. I was delighted when the driver rolled the truck and he didn't install another one. He eventually lost his license for developing all his x-ray films in the local VA hospital film processors.
