Abstract:
In the continuous moving table imaging, high-speed imaging such as the echo planar method is implemented without deteriorating image quality, realizing a high-speed table movement, namely, high-speed imaging.In the magnetic resonance imaging apparatus, an imaging control means for controlling a magnetic field generation means, a transfer means, and a signal processing means executes an imaging sequence for applying multiple readout gradient magnetic fields to measure multiple nuclear magnetic resonance signals, after one-time application of an exciting RF pulse, while moving the transfer means. On this occasion, a positional deviation of the readout gradient magnetic fields given to the multiple nuclear magnetic resonance signals, caused by the movement of the transfer means, is calculated in advance as correction data, so that the measured nuclear magnetic resonance signals are corrected by the correction data.
