An Approach to 3-Dimensional Multi-Band Acquisition

Bruno Riemenschneider¹, Jakob Asslnder¹, Jrgen Hennig¹

Multi-band excitation in conjunction with a 3-dimensional read-out helps to overcome the limitation in number of slices that can be resolved with parallel imaging techniques. Other than slab-wise excitation, it leads to exploitation of the coil sensitivities in all three dimensions and inhomogeneities at the interface between adjacent slabs are avoided. The feasibility of the approach is demonstrated by a sample measurement with a 32-channel headcoil. The field of view of (0.192 m) with voxel size 3mm was measured in 400 ms.
