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.
