There was the possibility that tissue were noticeably different. fearful that Lauterbur would get credit for the supporting structure would not be Discovering that the NMR machine was his ideas and receive recognition that was sufficient to keep the magnets apart and useful in detecting cancer, Damadian rightfully his. could slam together with tremendous envisioned its use in the detection of heart Also in February 1976, Damadian’s force.
