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."
Robert Turner (scientist)
From 1988 until 1993 he worked as a researcher at the National Institutes of Health in Bethesda, MD. Working with Denis le Bihan, a French neuroradiologist, he initially showed that EPI could be used to provide high quality maps of water diffusion in brain tissue, a discovery (known as Diffusion MRI) which has led to the widespread clinical use of MRI in stroke, where water diffusion in the affected brain tissue drops very rapidly after the ischemic event. The technique also lies at the heart of diffusion tensor imaging, a method for non-invasive study of connecting pathways within the brain’s white matter.
