Magnetic resonance imaging system

An MRI system includes an MR signal acquisition section, an imaging processing section, a control signal generating section, and a control section. The MR signal acquisition section excites an MR phenomenon in a portion including a selected slice of an object to be examined, and detects MR signals generated by the MR phenomenon. The imaging processing section processes the MR signals to form an image based on MR data in the selected slice of the object. The control signal generating section generates a control signal for acquiring the MR signals in response to movement of the object. The control section controls the MR excitation operation and the MR signal acquisition operation of the MR signal acquisition section in accordance with the control signal.
