The History of MRI
The history of MRI dates back to 1946 and starts with Felix Bloch, who proposed that the atomic nucleus behaves like a magnet. He realized that magnetic field could be produced as protons could spin around their own axis. Thus, protons have magnetic momentum. Then in late 1960s, Raymond Damadian discovered that malignant tissue had a different NMR (nuclear magnetic resonance) parameter as compared to normal tissue. Damadian concluded that based on the variation of these parameters, tissue characterization is possible. In 1977, Damadian and his team constructed Indomitable- the first super conducting NMR scanner that produced the first image of the human body.
