1. A method for establishing excitation parameters for a MR imaging captured by an MR device, comprising: parallel exciting the MR device using a plurality of transmit channels of the MR device; parallel capturing image data of an examination object using a plurality of receive channels of the MR device; determining elements of a k-space covariance matrix for a signal noise of the captured image data in a k-space; mathematically determining elements of an image space covariance matrix for a plurality of voxels in a region of interest of the examination object as a function of the k-space covariance matrix; and establishing the excitation parameters as a function of the elements of the image space covariance matrix, wherein an excitation profile is determined by minimizing an evaluation function that is dependent on diagonal elements of the image space covariance matrix corresponding to the plurality of voxels in the region of interest.
