The QUAD™ 12000, a product of FONAR Corporation, is the most open of all the so-called "Open MRIs." Open on all four sides and with an unusually large space in which patients can rest comfortably, the QUAD™ 12000 is considered a godsend for claustrophobic and very large patients.

The magnetic field strength of the QUAD™ 12000 is 0.6 Tesla, which is twice that of most Open MRIs. That extra strength, coupled with its full array of solenoidal surface coils, enables the QUAD™ 12000 to produce diagnostic pictures of exceptional quality.
