A new method of two-or three-dimensional spin density imaging by nuclear magnetic
resonance (NMR) is proposed, which exploits the properties of spin echoes in time-
dependent magnetic field gradients. An analysis shows that simultaneous observation and
differentiation of signals, arising from all spins distributed in a plane or set of planes within
the specimen, is possible. The method is thus capable of producing visual pictures faster
than previously described planar imaging methods.
