I went to the dentist this morning and needed an X-ray of part of my jaw. Nothing terribly exciting about that except that this time it was rather different. When I've had X-rays like this before the dentist stuffs a piece of cardboard in your mouth (containing the film), zaps you with the X-rays and then the film has to go away to be developed. The age of digital photography has now been extended to this area as well. Now the dentist puts a flat sensor in your mouth which is connected to a PC. After zapping you with X-rays the image is displayed straightaway on the screen of the PC. Cool! If you don't like the shot, just take it again (of course using X-ray radiation may mean you don't want to do it too often).

I wonder how easy it would be to connect one of these sensors to a Sun SPOT? Of course running the X-ray source off the SPOT might be a bit difficult.

I really must start carrying around a USB pen drive with me so I can get a copy of images like this.
