Results from continuing investigation of non-rectangular slice excitation profiles with the goal of providing improved results when used to reconstruct overlapping-slice 2D acquisitions leveraging knowledge of the slice profile are presented. A simulation of the excitation/acquisition process and accompanying reconstruction has been developed to aid the exploration of non-traditional slice profiles and their impact on the final reconstruction quality.
