www.gehealthcare.com/usen/mr/open_speed/index.html From GE Healthcare;
a friendly and less confining appearance targets the 7% of individuals who refuse to have an MRI because of claustrophobia. This open MRI system is also up to three times faster than other scanners, therefore the Signa OpenSpeed™ reducing exam time and scheduling issues. In addition, a swing table provides better access and supports up to 500 pounds.
