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 OpenSpeedâ„¢ reducing exam time and scheduling issues. In addition, a swing table provides better access and supports up to 500 pounds.

http://www.medical.toshiba.com/clinical/radiology/vantage.htm From Toshiba America Medical Systems Inc.;
With its high-field strength, the Vantageâ„¢ delivers the clinical capabilities and image quality expected by cardiologists, while simultaneously offering patients a more comfortable and non-invasive option, said Dane Peshe, director, MRI Business Unit, Toshiba America Medical Systems. Vantageâ„¢ supports a full complement of cardiovascular imaging studies, ranging from stroke evaluation to peripheral vascular imaging. Additionally, the ultra short bore design offers patients a greater feeling of openness that reduces claustrophobic sensations, while Toshiba's exclusive, patented Pianissimoâ„¢ technology reduces scan noise by as much as 90 percent for a more pleasant experience.'

www.canamglobal.com/mri/virgomri.html From Millennium Technology Inc. This open C-shaped MRI system eases patient comfort and technologist maneuverability. This low cost scanner is build for a wide range of applications. The Virgo™ patient table is detachable and moves on easy rolling castors. Able to accommodate patient weights up to 160 kg, the tabletop has a range of motion of 30 cm in the lateral direction and 90cm in the longitudinal direction. Images generated with this scanner can only be viewed (without data loss) on Millennium's proprietary viewing software.
