Pi 3 X-Ray! @raspberry_pi #RaspberryPi #Pi3
This image was made using a using a highly modified Scanmax 20 X-Ray mail scanner that I found via eBay (yes, really). I have substantially altered the imaging system; it now comprises a Kodak Lanex fine fluorescent screen and a Nikon D3100 camera, replacing the original high brightness, low resolution screen and video-based image capture and display. The result is a dramatic increase in resolution over the original 1 pixel per mm or so.
Images are further improved by multiple captures post-processed in Registax 6, which does a kind of intelligent averaging to reduce noise and enhance resolution. This image is made from about 12 exposures. There is some residual noise, of course, but it would take several dozen more exposures to make any significant improvement in signal to noise ratio (or resolution).
