The concepts of spatiotemporal encoding are exploited to design a new class of multidimensional pulses. In particular, 2D pulses are implemented, which operate in a hybrid direct and reciprocal excitation space. These hybrid 2D pulses are shown to be compatible with SPEN as well as Fourier imaging. In the case of Fourier imaging, a self-unfolding mechanism can be used to retrieve the region of interest even when it overlaps with excitation sidebands, thus allowing for larger bandwidths. Phantom experiments at 7T are used to illustrate the properties of SPEN-based multidimensional pulses.
