The shoe fitting fluoroscope was a common device used in shoe stores from 1930 through the 1950s.
Basically, it was a wooden box with an open x-ray tube and no reliable shielding to protect bystanders. You may want to think of it as an X-Ray Bomb, everyone near the machine was getting a full dose of radiation for 5 to 45 seconds at a time.

It was first used on soldiers in the military to speed up the processing of large numbers of injured personnel.
Many shoe salespersons put their hands into the x-ray beam to squeeze the shoe during the fitting.

Reminds me of autonomous vehicles and other “new and improved” things that we are told today are the wave of the future
