Abstract
The present invention provides a method and system to reduce the problem of signal dropout in data acquired using gradient-echo and asymmetric spin-echo magnetic resonance techniques, caused by linear susceptibility gradients in the direction of slice-selection. Specifically an algorithm is used to determine the optimal parameters of a tailored radiofrequency pulse along with the accompanying slice-selection and slice-refocusing gradients to correct this signal dropout.
