13. A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors of an imaging apparatus that includes at least one sensor and correction circuitry, cause the imaging apparatus to correct for a patient movement during an imaging examination via the imaging apparatus by:
outputting, via the at least one sensor, a signal containing information on movement of a diagnostically-relevant body region of the patient, the at least one sensor comprising a non-imaging sensor;
positioning the patient in an image recording region of the imaging apparatus;
performing the imaging examination for acquiring image data from the diagnostically-relevant body region of the patient;
acquiring the signal from the at least one sensor; and
performing a correction technique via the correction circuitry based upon the signal acquired from the at least one sensor to reduce an influence of the movement of the diagnostically-relevant body region of the patient on the imaging examination, wherein the imaging apparatus is a magnetic resonance imaging system with a local coil, and
wherein the instructions, when executed by the one or more processors of the imaging apparatus, further cause the imaging apparatus to correct for the patient movement by modulating the signal from the at least one sensor onto a magnetic resonance signal acquired via the local coil.
