MAGNETIC RESONANCE IMAGING DEVICE

摘要

There is provided a magnetic resonance imaging method rapidly performing biological movement correction with a high accuracy by using the radial sampling method or the hybrid radial method combining the radial sampling method with the phase encoding. From acquisition data on at least two blocks consisting of a pluralities of echo signal groups, a partial data arrangement of a low space frequency area such as a data arrangement on the circle along the circular trace of k-space is extracted. A phase difference between a data arrangement of the block serving as a reference and the data arrangement of the other block is calculated to perform rotation correction. Next, for the data after the rotation correction, a phase difference is calculated and parallel movement correction is performed. Echo signal groups of all the blocks after the correction are combined to reconstitute a final image.
