Abstract
An evolutionary algorithm has been used to design a family of shaped radiofrequency pulses giving uniform absorption‐mode excitation across a predetermined frequency band. By allowing a free precession interval before signal acquisition, time is left for field gradients to be switched and for undesirable transients to decay. © 1991 Academic Press, Inc.Keywords
