Robust self-navigating MRI using large coil arrays
A method for providing at least one motion corrected magnetic resonance imaging (MRI) image of an object in an MRI system with an array of a plurality of receiving coils is provided. At least one motion navigator signal of the object is provided. Individual navigator data are collected from each of the plurality of receiving coils. Motion estimates are generated for each of the plurality of receiving coils from the collected individual navigator data. A subset of the plurality of coils is found that detects a dominant motion by clustering the generated motion estimates. Only motion estimates from coils in the found subset are used to create a determined motion estimate. At least one MRI image is reconstructed using the determined motion estimate.
