(Open-Source CT Scanner)
When Peter Jansen realized the extreme price of a CT scan in the US (compared to in Canada), he was inspired to build his own CT scanner for less than the cost of a single scan.
Mechanically, this prototype scanner is very similar to the first generation of CT scanners, and it’s almost entirely laser cut. An object is placed on a moving table that goes through the center of a rotating ring. Inside the ring there’s a very low intensity x-ray source, and on the other side a detector. An Arduino Uno with a custom shield controls four stepper motors and interfaces with the detector. For safety I’m using a radioisotope x-ray source that’s barely above background levels, so every photon counts, and I’ve only just recalibrated the detector. I’m expecting the first images with a few more weekends of work.
