Raymond Damadian
Damadian has received several prizes. In 2001, the Lemelson-MIT Prize Program bestowed its $100,000 Lifetime Achievement Award on Damadian as "the man who invented the MRI scanner." He went on to collaborate with Wilson Greatbach, one early developer of the implantable pacemaker, to develop an MRI-compatible pacemaker. The Franklin Institute in Philadelphia gave its recognition of Damadian's work on MRI with the Bower Award in Business Leadership. He was also named Knights of Vartan 2003 "Man of the Year". He received a National Medal of Technology in 1988 and was inducted in the National Inventors Hall of Fame in 1989.
Magnetic resonance imaging of the brain
The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography and , obtained the first images and later patented diffusion MRI. In 1988, Arno Villringer and colleagues demonstrated that susceptibility contrast agents may be employed in perfusion MRI. In 1990, Seiji Ogawa at AT&T Bell labs recognized that oxygen-depleted blood with dHb was attracted to a magnetic field, and discovered the technique that underlies Functional Magnetic Resonance Imaging (fMRI).
