Parallel imaging performance is continuously rising, achieving high acceleration factors. SENSE, as a major parallel imaging method, however requires accurate coil sensitivity maps to create high quality images. Standard low-resolution reference scan approaches can fail, which may result in an image artifact in the reconstructed image. This abstract presents an approach to estimate the coil sensitivities, taking the basic coil geometry and a wave propagation model into account. First in-vivo studies on different anatomies are very promising.
