  • Title: Optimization of sensitivity encoding with arbitrary k-space trajectories.
    Author: Bydder M, Perthen JE, Du J.
    Journal: Magn Reson Imaging; 2007 Oct; 25(8):1123-9. PubMed ID: 17905244.
    Abstract:
    Sensitivity encoding (SENSE) is a magnetic resonance technique that unifies gradient and receive coil encoding. SENSE reconstructs the image by solving a large, ill-conditioned inverse problem, which generally requires regularization and preconditioning. The present study suggests a simple heuristic for determining the regularization parameter. Also discussed are the use of density weighting and intensity correction as preconditioners and the role that coil sensitivity estimation has in regularization. A modification to the intensity correction is proposed for use with a phase constraint.
