Interface of an X-ray machine

Answer 1

I had to look this up, but it sounded intriguing. After all, people made X-rays on machines whose "interface" was a knob for the last 100 years. It should be obvious to all that since knobs no longer work for anything, there have to be a billion buttons and a Windows interface on it, right? Turns out there are two kinds of X-ray machines on the market today--digital and analog. A digital X-ray machine is pretty nice if you've got a computerized hospital--you can take a picture of someone in a hospital in Alaska and a radiologist in Seattle, or at the Mayo Clinic, can read the X-ray from the comfort of her own office. Those machines have fancy Windows-based interfaces. Then there are analog machines, which expose film--still a very viable technology because instead of putting a CD containing a patient's X-rays in his record, and hoping the hospital's new computer will read it ten years down the road or the hospital ten miles down the road has a computer that can read the X-ray file format, you put the film in the record and read it by holding it up in front of the window. They still have knobs, or up/down pushbuttons that do the same thing.
