Having worked at several hospitals and imaging centers, I always find it interesting to see the variation between the x-ray equipment that is used. One facility I worked at had a Picker x-ray tube from 1958, and to my knowledge, it is still being used at that facility (although I'm certain the original tube inside the housing is probably long gone). Some places have brand-spanking new equipment, and most have something in between.
I would LOVE to get a library of images of different faces of x-ray tube controls... would anyone be willing to contribute some images to this library? If I get enough, I plan to create a dedicated page to display them all on this blog. Just send me a quick picture of the x-ray tube controls similar to the ones above.
