Behind the Scenes Minis: Medical Scans and Nobel Prizes

Once Dr. Ray Damadian had the idea to create a machine that used nuclear magnetic resonance to capture diagnostic data by scanning a human body, he still had to build it. And though he did, other scientists got credit for inventing the MRI.

Magnetic Resonance Imaging, Part 2

Who invented the MRI? Well, that's actually tricky to say, and it is a topic that still opens debate. In this first part, we'll talk about the various developments in physics that led to the idea of an MRI machine even existing.
