A
design of a composite refocusing pulse suitable for use in human imaging at
7T is presented here. With the assumption that it is preceded by a
slice-selective excitation, the refocusing solution is immune to
inhomogeneities within a predefined space of B1+ and
δB0 values for 7T human head imaging.
