发明名称 Eddy current correction method and magnetic resonance imaging apparatus
摘要 For the purpose of conducting optimal eddy current correction within a limited output range, a corrective value for eddy current correction for a gradient magnetic field is calculated, if the calculated value does not exceed a predetermined upper limit value, correction is conducted on the gradient magnetic field using the calculated value, and if the calculated value exceeds the predetermined upper limit value, a plurality of gradient magnetic fields affected by eddy current are simulated using a plurality of candidate corrective values not greater than the upper limit value, and correction is conducted on the gradient magnetic field using a candidate corrective value by which a relatively optimal gradient magnetic field can be obtained.
