Claim:
1. A method for providing magnetic resonance imaging (MRI) data for an image reconstruction to be carried out by an evaluation apparatus on a MRI base unit of a MRI system, wherein the MRI data is formed by MRI reception signals obtained by a MRI local coil unit of the MRI system, the method comprising: producing an alternating magnetic field by the MRI base unit, wherein the alternating magnetic field is modulated in accordance with a reference clock; obtaining electric energy for supplying local electronics of the MRI local coil unit from the alternating magnetic field by the MRI local coil unit; retrieving the reference clock from the alternating magnetic field by the local electronics, defining a retrieved reference clock; producing a radio signal containing MRI information representing the MRI reception signals and clock information representing the retrieved reference clock by the local electronics and transmitted to the MRI base unit; and processing the radio signal by the MRI base unit, wherein the MRI data and the clock information are retrieved therefrom and provided to the evaluation apparatus for the image reconstruction.
