MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD

摘要

The purpose of the present invention is to keep discontinuities between echoes from becoming large level differences in the k-space and to reduce artifacts that occur in the reconstructed image due to k-space discontinuities. When performing a fast spin echo method pulse sequence for collecting multiple echoes using spin-flip after a single RF excitation, this MRI apparatus controls the order of arrangement of the multiple echoes that are disposed in the k-space using the phase characteristics of the multiple echoes collected after a single RF excitation. The arrangement is controlled so that at least near the center of the k-space, echoes with small phase differences between the echoes are adjacent to each other.
