MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD FOR CORRECTING ERROR DUE TO GRADIENT MAGNETIC FIELD

摘要

The purpose of this invention is to reduce an artifact on an image that is caused by a gradient magnetic field error, in a non-orthogonal sampling method. For the purpose, when data used for an image reconstruction is obtained, data for correcting an error caused by a gradient magnetic field is obtained and the data used for the image reconstruction is corrected using the obtained correction data. In order to obtain the data for correcting the error, a block having a plurality of parallel echo signals is measured.
