Abstract
An MRI apparatus includes an imaging signal acquisition unit, a motion signal acquisition unit, a motion amount determination unit, a motion correction unit and an image reconstruction unit. The imaging signal acquisition unit acquires MR signals as imaging signals. The motion signal acquisition unit repetitively acquires MR signals having PE amount less than that of the imaging signals as motion signals. The motion amount determination unit obtains a motion amount using the motion signals. The motion correction unit performs correction processing of the imaging signals in accordance with the motion amount. The image reconstruction unit reconstructs an image using the imaging signals after the correction processing.
