ABSTRACT:
A method for suppressing image artifacts in a magnetic resonance imaging apparatus includes conducting an adjustment scan of the examination subject preceding or following the scan or scans which are used to acquire the measured data. The adjustment scan differs from measuring scan in that it is implemented without the generation of a phase-coding gradient. The data acquired in the adjustment scan are interpreted to identify any inadequacies in the generation of the raw data, and correction data are calculated. Using the correction data, the raw data sets which are Fourier-transformed in the read-out direction, are then corrected. N/2 ghosts can thus be suppressed, and the influence of inhomogeneities in the static field can be reduced.
