Abstract
A magnetic resonance imaging scanner includes a generally cylindrical main magnet assembly () that defines a cylinder axis (). A first set of shims () are rigidly positioned inside the magnet assembly () at about a first distance (d) relative to the cylinder axis (). A second set of shims () are rigidly positioned inside the main magnet assembly () at about a second distance (d) relative to the cylinder axis (). The second distance (d) is different from the first distance (d). A generally cylindrical radio frequency coil () is arranged inside the main magnet assembly () at about a third distance (d) relative to the cylinder axis (). A plurality of gradient coils () are arranged inside the main magnet assembly () at about a fourth distance (d) relative to the cylinder axis ().
