    In this work we present a method to combine complex-valued phased array MR data based on a uniform sensitivity approach, which
    incorporates sensitivity profiles calculated from afore acquired data. The algorithm was implemented on a clinical 3T whole-body
    MR-Scanner and embedded into the vendor-specific standard reconstruction chain.

    Additionally, it was linked with the GeneRalized Autocalibrating Partial Parallel Acquisition (GRAPPA) procedure to take advantage
    of partial parallel acquisition techniques as well. Thus, under-sampled data can be reconstructed with GRAPPA and subsequently
    combined with the presented method. Phase images reconstructed with the proposed method were in excellent agreement with reference
    data and did not suffer from errors due to incorrectly combined data.
