MOTION CORRECTION OF MAGNETIC RESONANCE IMAGES USING PHASE DIFFERENCE OF TWO ORTHOGONAL ACQUISITIONS |
摘要 |
Two magnetic resonance frequency domain data sets are acquired with the phase and frequency encoding gradient axes swapped. A k-space phase difference data set is computed from the two acquisitions and corrections for interview in-plane, rigid body translational motion are calculated from the phase difference information and a large set of simultaneous linear equations. The two acquired data sets are corrected with phase changes to compensate for the subject motion and then combined to form a single image.
