Reduced field-of-view (FOV) using two-dimensional spatially selective radio frequency (2DRF) excitation has been widely used for targeted, high-resolution diffusion weighted imaging (DWI). This work proposes a sheared 2DRF excitation scheme to rapidly and efficiently cover the excitation k-space. This approach not only enables extended slice coverage and preserves fat suppression capabilities, but also significantly improves the robustness against off-resonance-induced signal losses of 2DRF pulses.
