Multiband
MRI can be used to acquire
several slices at the same time. Here, we propose a new method
of multiband MRI based on Regularized Nonlinear Inversion (NLINV).
This method does not require a priori knowledge
about the coil sensitivities. Simultaneous estimation of
images and coil sensitivities of two slices is demonstrated from
six-fold undersampled data for a simulated multi-band acquisition.
