Cortico-spinal functional magnetic resonance imaging (fMRI) covering slices in the brain and cervical spinal cord usually involves specific geometry (field-of-view, voxel size) and timing parameters (bandwidth) for the two volumes. This requires a time-consuming and cumbersome retrospective reconstruction after the experiment because the standard program cannot handle the different parameter settings properly, e.g., for regridding of ramp-sampled data or correction of distortions induced by Maxwell terms. Here, a reconstruction program is presented that performs an optimized reconstruction on-the-fly including the correction of receive-coil inhomogeneities without the need of a retrospective reconstruction. It could help the applicability of cortico-spinal fMRI.
