Magnets, h atoms, radiofrequency coils, computer system. Understand the properties of the cryogen system (no uncontrolled quench) 1896: pupin - method of rapid x-ray photography. 1973: lauterbur - created magnetic field gradients used to locate signals. 1974: mansfield - created the selective excitation technique (lead to something similar to tomographic slices) 1975: ernst - fourier transforms (math; 2d imaging) 1978: first human head scan by emi (picker-marconi-philips machine & project) 1984: 0. 15t first clinical system london (t = tesla) Damadian - considered the father, first to publish his findings. Controversy surrounding that regarding a race to publish. Whoever publishes it first = gets the credit. Doesn"t mean they were the first to be successful. 1971: damadian discovered that tumours emitted a different signal than healthy tissue.
