ABSTRACT:
An MRI automatic power control system comprises a first unit for exciting each of a plurality of regions of a subject under examination with an excitation radio-frequency pulse of a different power, a second unit for acquiring magnetic resonance signals from the plurality of regions excited by the first unit, a third unit for identifying a maximum magnetic resonance signal contained in the magnetic resonance signals acquired by the second unit from the plurality of regions of the subject, and a fourth unit for storing the power of an excitation radio-frequency pulse that has provided the maximum magnetic resonance signal identified by the third unit as the optimum power of the excitation radio-frequency pulses.
