From FONAR Corporation;
in October of 2004, the company changed the product name of the Stand-Upâ„¢ MRI to the Uprightâ„¢ MRI. The Indomitableâ„¢, Uprightâ„¢ MRI is the only open MRI in the world that can perform positional MRI (pMRI), i.e. the Upright MRIâ„¢ scans patients in upright, weight-bearing positions, in addition to the conventional lie-down positions. The Uprightâ„¢ MRI is the only device that can scan patients in the position their symptoms occur, in their position of pain. In early clinical reports independently confirm the effectiveness and potential of positional MRI. In October 2000, Fonar received permission to market the Indomitableâ„¢ from the FDA.

High permeability structure used to concentrate the magnetic flux inside itself and thus decrease the magnetic fringe field and increase the field strength in the useful volume of a magnet.
