MAGNETIC RESONANCE IMAGING APPARATUS AND MAGNETIC RESONANCE IMAGING METHOD

摘要

A magnetic resonance imaging apparatus according to an embodiment includes sequence controlling circuitry and image generating circuitry. The sequence controlling circuitry executes a pulse sequence which applies a excitation pulse and then continuously applies a readout gradient magnetic field with alternating polarity thereof and acquires echo signals continuously generated by the pulse sequence from a plurality of receive channels. The image generating circuitry corrects the echo signals so as to generate an image, correcting the echo signals for all of the receive channels collectively on the basis of phase differences between echo signals corresponding to even lines of k-space and echo signals corresponding to odd lines of k-space, and corrects the echo signals for each of the receive channels individually on the basis of magnitude differences between echo signals corresponding to the even lines of k-space and echo signals corresponding to the odd lines of k-space.
