摘要
A new ultrafast imaging technique is presented that can be performed on standard, unmodified magnetic resonance imaging spectrometers. The method uses very few gradient switching steps and does not require that the switches are very rapid. It is based on the generation of a multiplicity of signals by a few radiofrequency (RF) pulses and their separate frequency- and phase-encoding before acquisition of all signals in a single period.
