Method and device for establishing excitation parameters for MR imaging

A method and a device for establishing excitation parameters, in particular for establishing an excitation profile, for MR imaging, are proposed. Elements of a k-space covariance matrix are determined for signal noise in k-space data which is captured using a plurality of receive channels in the context of data captured at an examination object. Elements of at least one image space covariance matrix are mathematically determined for a plurality of voxels of the examination object as a function of the k-space covariance matrix. The excitation parameters are established as a function of the determined elements of the at least one image space covariance matrix.
