Development of a rapid, automated shim approach for cardiac MR in mice in vivo

A novel, automated shim method, optimised for application to cardiac MR in mice, is reported. It is able to homogenize the B0-field in an arbitrarily shaped, but connected region of interest, using available linear, 2nd and 3rd order shim terms. Initial experiments in phantoms and mouse hearts in vivo show the superiority of this approach over manual shimming.
