Method and apparatus for rapid NMR imaging.

摘要

A method and apparatus provides complete mensuration of two-dimensional Fourier components of a nuclear spin property thereby pemitting undistorted image reconstruction. In apite of an unavoidable phase factor which originates from basic field inhomogeneities and drifts and from non-perfect electronics adjustment, an optimum sectional image is obtained from half measurements of the sampled resonance signals which are complex conjugate pairs. The image is obtained by determining the phase and then eliminating it from a spatial Fourier transform of the spin density distribution.
