  • Nuclear magnetic resonance imaging methods
    Patent number: 5252923
    Abstract: To derive NMR imaging information, an object is subjected to a static magnetic field and a sinusoidally time-varying magnetic gradient field G. A 90.degree. rf selective pulse P is applied around the time the gradient field G is zero and the subsequent free induction echoes E are detected and decoded. Additional non-selective pulses may be inserted at the times of echo peaks to refresh the echo signals. Additionally, to obtain two-dimensional information, the gradient direction of the magnetic gradient field may be changed in successive cycles of the sinusoidal field.
