Adiabatic refocusing pulse which compensates for variable rf power and off-resonance effects.

M R Bendall, M Garwood, K Uğurbil, D T Pegg.   

Abstract

Adiabatic 180 degrees inversion rf pulses can be converted to 180 degrees refocusing pulses by inverting the effective field midway during the pulse. Suitable pulses retain insensitivity to large variations in the rf field strength and act over a reasonable spectral width. Such pulses may find application in studies utilizing surface coils.
