Separation of slices simultaneously acquired in
multi-band EPI is problematic when the N/2 ghost needs
different correction parameters for different slices. We
present a straightforward manner of combining the
slice-dependent ghost correction with multiband SENSE.
The method inverts the sensitivity encoding equations
for separately reconstructed even- and odd-echo data. It
achieves a significant complexity reduction compared to
the previously proposed k-space-based approach.
