Abstract
A method of compensating for eddy currents induced by the switching on and off magnetic fields in gradient coils in NMR imaging apparatuses, which method includes at least one compensation cycle including the steps of performing at least one detection of the magnetic field generated by the current flowing in a gradient coil, i.e., a gradient field; extrapolating the course of the effectively generated gradient field from the data of said at least one detection; generating a gradient fields excitation current compensating the eddy current effects on the gradient fields on the basis of the comparison of the effectively generated gradient fields and of the target gradient field.
