Many already know that the hospital fees can really add up in the US, even with proper health insurance. Engineer Will Osman found out that hard way when he received a hospital bill for nearly $70,000 USD that covered a 2-night stay, including a set of X-rays. Fortunately, his insurance covered most of the bill, leaving him with $2,500 to pay out of pocket, but he decided to take things into his own hands by building a functional X-ray machine at home.
In all, he spent less than $2500 for a power supply, X-ray vacuum tube, Geiger counters and a roll of sheet metal. Some of these things definitely should not be handled by a non-professional, especially anything that involves radiation. His initial prototype did not image the X-rays very well, so an intensifying screen was added to convert them into visible light. This visible light, or photons, are then captured by a DSLR camera.

I used 40kV silicone insulated wire and surrounded that with additional silicone tubing, and then just stayed away from the tube during operation. After the initial tests, a giant 2mm lead sheet was placed around the tube,” said Osman.
