The application of nonlinear spatial encoding magnetic fields for both excitation and geometrically matched encoding allows the acquisition of curved slices with adjustable shape and thus increases the flexibility of MRI. However, both spatially varying slice thickness and in-plane resolution resulting from the nonlinearity of the fields is an unwanted side effect for most applications. The purpose of this study is to reduce the spatial variation of the voxel sizes. This is obtained by applying a concept for alias-free undersampling previously developed for PatLoc imaging.
