ABSTRACT:
A magnetic resonance imaging system comprises a static field generating section for generating a static field applied to an object, a gradient field application section for applying a gradient field in the form of a pulse to the object disposed in the static field, a high frequency wave transmitting/receiving section for applying an excitation pulse of a high frequency field to the object disposed in the static field and for detecting a magnetic resonance signal excited in the object, and a controlling/processing section for driving the gradient field application section and high frequency wave transmitting/receiving section at a predetermined timing and for processing the magnetic resonance signal to obtain magnetic resonance image data. The system further comprises at least one auxiliary coil, and a current supply section for supplying a current for compensating to the auxiliary coil.
