Magnetic resonance imaging has brought about a revolution in medicine, particularly in imaginology. In its process of development, mathematicians, physicists, chemists, engineers, and physicians made important contributions by working up seemingly unrelated concepts with no current usefulness to implement an impressive tecnique by joining together such diverse elements as Fourier and Radon Transforms; spin concept; nuclear spin; measurement of magnetic moments in protons, neutrons, condensed matter, and tissues; in the solving of integral equations; backprojection; diffusion; gradients; spatial encoding; K-space; double-pass Fourier transform, and image construction...
