Multiphase sensitive detection at constant time on the free induction decay of the magnetization after an RF-pulse and phase encoding the signals in relation to the detectors result in high-resolution magnetic resonance instant imaging. The field gradient for spatial resolution is assumed to be static and linear. The method applies to NMR as well as EPR, for gases, liquids and solids. (c) 2007 Elsevier B.V. All rights reserved.
