The ExLoc technique allows for excitation and
geometrically matched local encoding of curved slices
based on set of nonlinear magnetic encoding fields. For
robust sequences such as gradient echo, the variation in
image resolution resulting from the field nonlinearity
can be compensated by the local FOV technique. In this
study we explore the applicability of the local FOV
technique to ExLoc echo planar imaging. ExLoc echo
planar imaging is in particular promising for curved
slice functional imaging. However, the underlying
continuous trajectory is highly sensitive to B0
inhomogeneities.
