ABSTRACT:
An image reconstruction method for a magnetic resonance imaging device is disclosed, by which phase distortions of a magnetic resonance signal are stored in the form of a table prepared previously, by using a phase encode amount and an imaging region size as parameters; the phase distortions of the magnetic resonance signal are corrected on the basis of the phase distortions stored in the table for the measured magnetic resonance signal or the phase distortions varying for every line are presumed from the difference in the phase between the phase of hypothetical data including no phase distortions and the phase of measured data; and the phase distortions of the measured magnetic resonance signal are corrected by using this presumed value.
