Planar spin imaging by NMR

Abstract

A new method of spin-density imaging by NMR is described which allows simultaneous observation and differentiation of signals arising from spins distributed throughout a thin layer or plane within the specimen. The method, which is based on selective rf irradiation of the sample in switched magnetic field gradients, can produce visual pictures considerably faster than previously described line-scan imaging methods. Some simple examples of two-dimensional images obtained by the method are presented. © 1977.
