K-space description for MR imaging of dynamic objects

Q S Xiang et al. Magn Reson Med. 1993 Mar.

Abstract

The spatial frequency (k) space concept is extended to describe the imaging of time-dependent objects. This work builds on the existing k-space description of MRI and is useful for simplifying the analysis of explanations of motion artifacts, algorithms for the correction of motion, and efficient imaging schemes for dynamic objects. Specific examples of the use of this concept for different imaging techniques are presented.
