ABSTRACT:
A pulsed strong magnetic field is applied to an object creating a magnetic moment distribution. Following the pulse a set of spatially orthogonal gradient fields pointed normal to the magnetic moments are used to cause the magnetic moments to precess around the axis of the gradient fields, producing time-varying magnetic fields indicative of the spatial distribution of the magnetic moments. These are then detected, processed and used to make magnetic resonance images of the object.
