Correction Method for Thin Slice Spectral Spatial RF Pulses

Yuval Zur¹

Spectral spatial (spsp) RF pulses are used for simultaneous fat suppression and slice selective excitation. However, spsp pulses are very sensitive to RF gradient delay and eddy currents. We present a correction method, such that spsp pulses are, in practice, not sensitive to system imperfections. This correction enables practical use of spsp RF pulses with slice width of 1.5 mm at high field strength (3T).
