Abstract

Provided is a technique of suppressing an extension of an imaging time and performing high-accuracy N/2 ghost correction in imaging in which a signal is collected by EPI. A one-shot pre-scan in which a blip-shaped phase-encoding gradient magnetic field is executed alternately in an EPI sequence is performed to generate N/2 ghost-free data having different polarities, and pseudo N/2 ghost data is created from the N/2 ghost-free data. A correction kernel based on a signal of a measurement point to be corrected and signals of measurement points on an even line and an odd line around the measurement point is calculated using the pseudo N/2 ghost data. The main scan data is corrected using the correction kernel with respect to the signals of the measurement point to be corrected and the measurement points on the even line and the odd line around the measurement point.
