1. A magnetic resonance imaging apparatus, comprising:
a measurement unit configured to measure a nuclear magnetic resonance signal of a subject;
a calculation unit configured to generate an image by using the nuclear magnetic resonance signal measured by the measurement unit;
a control unit configured to control operations of the measurement unit and the calculation unit; and
a body motion analysis unit configured to receive, from a sensing unit disposed to be physically separated from the subject and configured to detect a body motion of the subject, a body motion detection result, and analyze a spatial characteristic and a temporal characteristic of the body motion, wherein
the control unit includes a processing determination unit configured
to determine, by using body motion information obtained by the body motion analysis unit analyzing the body motion, a change in processing of at least one of the measurement unit and the calculation unit, and
to specify, based on the body motion information, a nuclear magnetic resonance signal to be excluded from the nuclear magnetic resonance signal used by the calculation unit for image generation, and
the control unit is further configured to control the processing by the calculation unit to exclude the nuclear magnetic resonance signal to be excluded, from the image generated by the calculation unit, according to the determination result of the processing determination unit.
