Patent ID: 8649846

Claim:
A magnetic resonance imaging apparatus comprising: an imaging condition setting unit configured to set an imaging sequence for acquiring imaging data, a dummy shot sequence prior to the imaging sequence, a correction use sequence and an acoustic control sequence, the imaging condition setting unit including: an acoustic control unit configured to set the dummy shot sequence and the acoustic sequence such that the dummy shot sequence is performed in synchronization with a signal representing a respiratory body motion, while applying an excitation pulse together with a slice selection gradient, the excitation pulse and a repetition time thereof in the dummy shot sequence being the same as those in the imaging sequence, wherein the acoustic control sequence is performed by adding a gradient magnetic field for an acoustic control to the correction use sequence; a correction data acquisition unit configured to acquire, in a period of the dummy shot sequence, correction use data or correcting an influence of a respiratory body motion on image data in synchronization with a signal representing the respiratory body motion, the correction use data being two-dimensional image data with a low resolution in an X-axis and a Y-axis direction; an adjusting unit configured to adjust the period of the dummy shot sequence so as to keep a repetition time for acquiring the imaging data constant; a data acquisition unit configured to acquire imaging data for imaging subsequently to acquiring the correction use data; and a correction unit configured to generate image data by correcting the influence of the respiratory body motion based on a position shift in each of the X-axis and Y-axis directions in the correction use data.
