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.
