Claim:
1. A method for estimating an output gradient magnetic field waveform in a magnetic resonance imaging apparatus, the gradient magnetic field waveform estimating method comprising: inputting at least two kinds of input values to a gradient magnetic field generation section and measuring output values of an output gradient magnetic field waveform that the gradient magnetic field generation section generates using the input values, in a state in which a control parameter of the gradient magnetic field generation section is disabled so that an operation is not performed by the gradient magnetic field generation section; calculating a response function of the gradient magnetic field generation section, which includes effects of a plurality of factors affecting the output gradient magnetic field waveform, using the at least two kinds of input values and measured output values corresponding to the input values; and calculating an estimated value of an output gradient magnetic field waveform with respect to an input value of a desired gradient magnetic field using the response function.
