It is shown how transverse magnetization can be excited with a single low-power radio-frequency pulse consisting of a superposition of two frequency-modulated components. The phase dispersion obtained with this self-refocusing pulse is very small over bandwidths that are far greater than the amplitu
## Abstract We have developed and validated the performance of a novel slice selective pulse sequence that allows direct calibration of the RF field using a simple rectangular pulse. The new sequence offers a number of substantial advantages. It operates at steady state and has an accurate calibrat
