I had my knees x-rayed yesterday (no good news there) and it was done
using a Fuji FCR XC-2 digital processor. Or at least the x-ray tech
told me is was digital but couldn't explain how it worked. I couldn't
figure it out since I expected a digital sensor that was wired directly
to a computer. Much to my surprise the "sensor" seemed to be no
different than a film plate. Just a rectangular, olive colored
cartridge roughly 11x17x1" wrapped with an aluminum frame around it.
After the exposure was made the cartridge was removed (as though it was
film) and taken over the the Fuji processor where I could no longer see
what was going on.
After the x-rays were done and I discovered that grilling the x-ray tech
was getting me no useful information I wrote down the name and model
number of the machine and looked it up on the web. The technology is
"storage phosphor technology" (SPT) and operates in a vaguely similar
manner to storage phosphor display tubes used on oscilloscopes and
analog graphic display devices of many years ago.
Anyhow, I thought some of you might find the technology description
interesting as did I. It's not the digital imaging technology we've
come to know in our cameras. <http://www.alara.com/about/spt.html>
