 Zusammenfassung: Parallel imaging is intrinsically limited by Maxwell’s equations. A complete set of vector solutions to the Helmholtz equation consists of both curl-free and divergence-free fields. In this study we investigated the contribution of electric-type current patterns to UISNR for different voxel positions and acceleration factors in a spherical model at 9.4T. For moderate acceleration the electric mode increased UISNR by maximally 55. For very high acceleration, however, UISNR was mostly caused by the magnetic mode. The reason for this might be the much faster growing power loss of the electric mode with respect to the expansion order.
