In this contribution a method for the estimation of Superresolution performance is presented. For adequately designed reconstruction methods, the modulations of the rf coil sensitivities can be used to extend the acquired gradient-encoded k-space region. This extension directly results in a resolution improvement. The k-space representation of the sensitivity maps gives a global estimate about the degree of this k-space extension. Resolution is investigated by performing a point spread function analysis. Simulated data are presented and verified with measurement results based on a standard 2D-CSI sequence.
