www.gehealthcare.com/usen/mr/index.html From GE Healthcare;
The Signa SP 0.5T™ is an open MRI magnet that is designed for use in interventional radiology and intra-operative imaging. The vertical gap configuration increases patient positioning options, improves patient observation, and allows continuous access to the patient during imaging. The magnet enclosure also incorporates an intercom, patient observation video camera, laser patient alignment lights, and task lighting in the imaging volume.

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.

www.vitalcom.com/euen/mri/products/signa-hde-15t/index.html From GE Healthcare;
GE Healthcare has added the Signa HDe 1.5T™, a compact MRI device at an affordable price to its family of MRI products. It has a single electronic cabinet that can be positioned inside the scanner room rather than in a separate equipment room. The Signa HDe 1.5T can be installed in the same physical location as 0.5T MRI systems with minimal construction costs. According to GE, the installation has been simplified to last only 7 days and has a 30 percent smaller footprint than a typical 1.5T system.
The 1.5T Signa™ HDe MRI system is substantially equivalent to the currently marketed GE 1.5T machines. The data acquisition system supports 1, 4, 8 independent receive channels and multiple independent coil elements per channel during a single acquisition series. The gradient specifications of HDe are lower than other GE Signa 1.5T MRI systems, but it can support clinical applications in cardiac and spectroscopy imaging.
