Abstract:
1. A magnetic resonance imaging apparatus comprising: a scanning device configured to repetitively perform an imaging sequence in which an electromagnetic wave is emitted toward a subject in a static magnetic field space to excite an imaged region in the subject, and magnetic resonance signals generated in the imaged region in the subject are acquired as imaging data; a body motion detecting device configured to repetitively detect a displacement caused by body motion of the subject each time said scanning device performs the imaging sequence; a raw data selecting device configured to select the imaging data acquired by said scanning device performing the imaging sequence as raw data based on the displacement caused by body motion of the subject detected by said body motion detecting device; and an image producing device configured to produce an image of the subject based on the imaging data selected as raw data by said raw data selecting device, wherein said body motion detecting device is configured to detect, as the displacement caused by body motion of the subject, a first displacement before said scanning device performs the imaging sequence and a second displacement after said scanning device has performed the imaging sequence, and said raw data selecting device is configured to select the imaging data as raw data based on the first displacement detected by said body motion detecting device and the second displacement detected by said body motion detecting device.
