摘要： According to one embodiment, a magnetic resonance imaging apparatus includes an electrocardio information acquisition unit and an image data generation unit. The electrocardio information acquisition unit acquires a magnetic resonance signal for estimating an electrocardiogram signal of an object in sync with a biomedical signal other than an electrocardiogram signal. The biomedical signal is acquired from the object and shows a cardiac beat. The electrocardio information acquisition unit further determines a time difference between a position of a reference wave of the electrocardiogram signal and a synchronous position of the biomedical signal. The position of the reference wave is estimated from the acquired magnetic resonance signal. The image data generation unit acquires a magnetic resonance signal for imaging corresponding to a specific time phase of the cardiac cycle in sync with the biomedical signal based on the time difference, to generate an image data corresponding to the specific time phase of the cardiac cycle from the acquired magnetic resonance signal for imaging.
