MAGNETOM Aera
 
www.healthcare.siemens.com/magnetic-resonance-imaging/0-35-to-1-5t-mri-scanner/magnetom-aera/ From Siemens Medical Systems;
Received FDA clearance in 2010.
The MAGNETOM Aera is a patient friendly, comfortable 1.5 Tesla MRI system with advanced radio frequency chain.
The system is equipped with the Tim 4G and Dot system (Total imaging matrix + Day optimizing throughput), to enhance both productivity and image quality.
Tim 4G technology provides improved SNR. The standard system configuration of 48 radio frequency channels and 204 coil elements creates an imaging matrix that allows maximum use of coil elements at full field of view. Dot provides improved image consistency through new features like auto align, auto FoV and automatic bolus detection.

test.med.siemens.com/magnetom/rsna_chicago_2003/tim/avanto/index.php From Siemens Medical Systems; MAGNETOM Avanto with Tim - Total imaging matrix technology. For true whole-body anatomical coverage. For ultra-fast image acquisition. Aids the physician in fast and precise evaluation of systemic diseases like colon cancer, metastasis imaging, vessel diseases, and preventional exams. For claustrophobic patients, MAGNETOM Avanto enables feetfirst exams for nearly all MR procedures. For obese patients, MAGNETOM Avanto supports up to 200 kg (400 lbs), without table movement restrictions. The AudioComfort technology enables up to a 30 dB(A) acoustic noise reduction, that means nearly all clinical routine sequences are running under 99 dB(A).
