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."
X-ray
Many experimenters, including Röntgen himself in his original experiments, came up with methods to view X-ray images "live" using some form of luminescent screen. Röntgen used a screen coated with barium platinocyanide. On February 5, 1896 live imaging devices were developed by both Italian scientist Enrico Salvioni (his "cryptoscope") and Professor McGie of Princeton University (his "Skiascope"), both using barium platinocyanide. American inventor Thomas Edison started research soon after Röntgen's discovery and investigated materials' ability to fluoresce when exposed to X-rays, finding that calcium tungstate was the most effective substance. In May 1896 he developed the first mass-produced live imaging device, his "Vitascope", later called the fluoroscope, which became the standard for medical X-ray examinations. Edison dropped X-ray research around 1903, before the death of Clarence Madison Dally, one of his glassblowers. Dally had a habit of testing X-ray tubes on his hands, and acquired a cancer in them so tenacious that both arms were amputated in a futile attempt to save his life and in 1904 he became the first known death attributed to X-ray exposure. During the time the fluoroscope was being developed Serbian American physicist Mihajlo Pupin, using a calcium tungstate screen developed by Edison, found that using a fluorescent screen decreased the exposure time it took to create a X-ray for medical imaging from an hour to a few minutes.
