Raymond Damadian

American physician and inventor (1936–2022)

Raymond Vahan Damadian (Armenian: Ռեյմոնդ Վահան Դամադյան; March 16, 1936 – August 3, 2022) was an American physician, medical researcher, and inventor of the first nuclear magnetic resonance (NMR) scanning machine. Damadian's research into sodium and potassium in living cells led him to his first experiments with nuclear magnetic resonance (NMR) which caused him to first propose the MR body scanner in 1969. Damadian discovered that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance (NMR) because of their prolonged relaxation times, both T1 (spin-lattice relaxation) or T2 (spin-spin relaxation).
