MAGNETOM Spectra
 
www.healthcare.siemens.com/magnetic-resonance-imaging/3t-mri-scanner/magnetom-spectra From Siemens Medical Systems;
Received FDA clearance in 2012.
The MAGNETOM Spectra is a cost-optimized high field MRI system with Tim 4G and Dot technologies. The system consumes less energy compared to other 3 Tesla scanners. The magnet-cooling helium is contained in a closed loop, which prevents the gas from escaping and reduces the need for refills. TimTX includes innovative techniques in the radio frequency excitation hardware as well as new application and processing features enabling uniform RF distribution in all body regions.

70 cm + 125 cm + 1.5T and Tim - a combination never seen before in MRI ... MAGNETOM Espree™s unique open bore design can accommodate more types of patients than other 1.5T systems on the market today, in particular the growing population of obese patients. The power of 1.5T combined with Tim technology boosts signal to noise, which is necessary to adequately image obese patients.
