Research Abstract

A computer simulation study of a three dimensional (3D) motion correction technique was carried out to suppress through-plane motion artifacts in MRI. The 3D data acquisition sampled spherical space successively within a rectangular block that rotated around the center of k-space. Low spatial resolution images were reconstructed with rectangular block data misaligned by 3D displacement of three translations and three rotations. Misalignments of rectangular block data were measured by correlation coefficient between these low spatial resolution images and one reconstructed with rectangular block data without 3D displacement. It was assumed that the object was stationary during data acquisition of the echo train length (ETL) and object motion occurred only during the quiescent period between each data-sampling period and the following excitation radio frequency (RF) pulse. A 3D motion correction is effective for bothin-plane and through-plane object motion in MRI.
