Abstract
A Fourier transformation imaging technique is used for NMR imaging. Spins in a selected plane are excited by selective RF pulses and an associated G.sub.z gradient and the selected spins are subjected to three mutually orthogonal gradients which provide the resonance signal with spatial resolution along each axis produced by phase encoding. The signals sampled and read out in the presence of a readout gradient are associated with spatial frequencies determined by the applied gradient fields. The Fourier transformation of the spin-echo signals obtained from repetition of the pulse sequences gives a two-dimensional image. The linear phase-encoding gradient is applied starting with a preliminary phase-encoding gradient which maximizes the spin-echo signals.
