William Woollard - MRI Scanner

There seems to be some controversy over who actually developed the Magnetic Resonating Image Scanner (MRI); what's absolutely certain is that this is one of the most important medical inventions ever devised. MRI works, as the name suggests, by manipulating a magnetic field, enabling doctors to probe deep within the human body. It's a technology that's improving all the time, and has already saved countless lives.
