ABSTRACT:
A method, and an apparatus for performing the method, are described, for imaging a region of a body using NMR in which part of the region is moving with a motion such that its displacement with respect to time is a nonmonotonic function during the time period over which NMR data signals are collected. The data signals are collected in an order dependent on the motion such that motion artifacts are reduced.
