MAGNETOM Verio
 
www.healthcare.siemens.com/magnetic-resonance-imaging/3t-mri-scanner/magnetom-verio From Siemens Medical Systems;
Received FDA clearance in 2007.
The MAGNETOM Verio provides up to 102 integrated matrix coil elements and up to 32 independent radiofrequency channels that allow flexible coil combinations to make patient and coil repositioning virtually unnecessary. The Tim (total imaging matrix) technology also increases patient throughput due to a shorter scan time.
The open bore design offers great comfort for patients of all shapes and sizes.

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.
