Part of a collaboration under NIH grant U01EB025153 is leading to the development of a highly compact brain imaging scanner. In order to realize the required B0 uniformity of the scanner, we have developed passive shimming techniques that will be robust despite a low field uniformity and non-cylindrical magnet warm bore layout. This presentation describes the methods and results we will use to shim our compact scanner.
