We propose a novel data acquisition and image reconstruction method for parallel magnetic resonance imaging. A modification to the parallel imaging system is proposed to allow simultaneous data acquisition using a coil with uniform sensitivity in addition to localized surface coils. The uniform sensitivity coil is included in the image reconstruction technique as an additional coil. The reconstructed image for this coil shows uniform intensity over the field of view that is significantly better than the conventional sum-of-squares reconstruction. The proposed method is tested using real MRI phantom data.
