%X Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection.We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally-selective GRAPE pulses. With a superimposed constant gradient field spatial selection was achieved. The method was tested in slice- and slab-selective imaging experiments.Universal spatially-selective GRAPE pulses increased FA homogeneity and SNR. In 2D gradient echoes, the SNR could be increased by approximately 6
