  • Moving gradient zeugmatography
    Patent number: 4307343
    Abstract: Nuclear magnetic resonance phenomena are employed to generate a two dimensional image of a thin planar slice through a body under investigation. The apparatus herein operates to determine the spin density distribution in a planar slab within the body which typically comprises a biological organism. Each pixel in the resulting image is distinguished by applying time-varying magnetic field gradients so that the frequency history of the spins in each pixel is uniquely distinguishable. Additionally, novel radio frequency excitation means assure selective excitation within the planar slab.
    Type: Grant
