摘要：

A wide variety of amplitude- or phase-modulated pulses, which are designed for selective excitation, inversion or refocusing, are severely perturbed by radiation damping effects in the presence of a large macroscopic magnetisation. A general method is presented to compensate for radiation damping during the application of selective rf pulses. This method, which has general applicability for any amplitude- or frequency-modulated rf pulse, is demonstrated experimentally for inversion pulses. (C) 1999 Elsevier Science B.V.
