DIY X-ray CT scanner controlled by an Arduino

DIY X-ray CT scanner controlled by an Arduino. Ben writes –

I built a CT scanner from an x-ray tube that I bought on eBay, a stepper motor, a large ring bearing, and an Arduino. I used a phosphor screen and my camera to capture x-ray shadow images of a frozen chicken, while the Arduino and stepper motor rotated the chicken by 8 degrees between shots. The resulting 45 images were combined via filtered back projection to create a 3D volume reconstruction of the chicken.

  1. Um, you are looking at some horrible injuries or death. Or are also breaking so many laws that your head should be spinning. The guy who sold you the tube also broke umpteen laws. In addition to all of the health and safety laws DHS frowns on the use of unlicensed x-ray devices.

    See the pretty letters after my name? Thats two years of college AFTER my BS. And then a certification.

  2. Indeed X-Rays are not something to be taken lightly. Lead apron, lead walls. I don’t see any of this in the video, so anyone in the next room over or house over is getting unknowingly dosed with X-Rays.

  3. Gamma rays are bad ju-ju…be very careful!…

  4. And so are X-rays from electrons (x-ray tubes) …just a slight shift in frequency and source but just as cell damaging…
