passbox

Here's another relic from the days of film... the passbox. One door is for exposed film cassettes, and the other is for unexposed ones. Two techs can work together this way, one shooting films in the exam room, and then handing them off via the passbox to a second tech working in the darkroom.

 

Under the passbox is a plastic "phantom". It has some bits of metal in it, and it's used to calibrate the c-arms. Next to the phantom is a little aluminum wedge. It's not used very much any more, but it can be used as a filter. You put it on the tube, and it compensates for patients' anatomy thickness variations--like a foot, where it's thick and dense near the ankle, but thin near the toes.
