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.
