Fourier transform imaging

0.01 sec.

Etymology: Jean B.J. Fourier

(in medical physics) nuclear magnetic resonance (NMR) imaging techniques in which at least one dimension is phase encoded by applying variable gradient pulses along that dimension before "reading out" the NMR signal with a gradient magnetic field perpendicular to the variable gradient. The Fourier transform is then used to reconstruct an image from the set of encoded NMR signals.
