ABSTRACT:
The present invention is intended to provide a phase error measuring method capable of measuring a phase error occurring in each phase encoding direction that corresponds to the direction of a readout magnetic field gradient which is turned in units of a radian. The phase error measuring method in accordance with the present invention is implemented in a magnetic resonance imaging (MRI) apparatus that performs a K-space filling scan to define data in a K-space having readout lines formed along a Kx axis, a Ky axis, and a mixed axis of them. The phase error measuring method includes a plurality of phase error measurement steps of measuring a phase error that occurs in each phase encoding direction corresponding to the direction of a readout magnetic field gradient which is turned in units of a radian.
