Raymond Damadian
Damadian received a National Medal of Technology in 1988 and was inducted into the National Inventors Hall of Fame in 1989. His original MRI full-body scanner was given to the Smithsonian Institution in the 1980s and is now on loan and on display at the National Inventors Hall of Fame in Ohio. In 2001, the Lemelson-MIT Prize Program bestowed its $100,000 Lifetime Achievement Award on Damadian as "the man who invented the MRI scanner."
Proton-enhanced nuclear induction spectroscopy
Proton-enhanced nuclear induction spectroscopy (PENIS), also sometimes called Cross Polarisation (CP), is a nuclear magnetic resonance technique invented by Michael Gibby and Alexander Pines while they were graduate students in the lab of Professor John S. Waugh at the Massachusetts Institute of Technology. It was one of the first of Pines' experiments transferring spin orientation from one atomic nucleus to another, which has been one of the running themes throughout his career as a leading pioneer in the applications of NMR to the study of non-liquid samples. The PENIS technique was patented in 1972.
