摘要：

A method of generating intense, short pulses of magnetic field gradient is described, for application in solid-state, multiple-pulse imaging. The gradient coil is resonated with an energy storage capacitor, producing a half-sinusoidal current waveform. Clean turnoff occurs automatically at a zero-crossing, so RF pulses may be used immediately before and/or after gradient pulses. © 1991.
