ExLoc allows excitation and geometrically matched spatial encoding of curved slices by the application of a set of nonlinear, but locally orthogonal, encoding fields. So far the concept could be demonstrated for slices with one curved dimension. In this study, we apply ExLoc to a planar gradient system, generating field components with nonlinear variation along all three dimensions. For the first time, this allows selection and encoding of slices with two curved dimensions.
