Original Abstract

Accurate knowledge of a gradient magnetic field waveform is important for measurement of diffusion coefficients in NMR. Diffusion coefficients are determinedfrom the decay between the MR signál affected and the one not affected by the gradient pulses. Therefore the waveform ofthe gradients is essenlial from the point ofview ofthe accuracy. Short ramp times, amplitudě of generated gradients and symmetry of positive and negative levels (i.e. integrál of two pulses with the samé amplitudě and inverse polarity is zero) are desirable.
