Siemens Healthcare has launched Magnetom Terra 7Tesla MRI system. The system is designed to translate cutting-edge MRI research results into clinical application, and it is the worlds first ultra-high field research system ready for future clinical use with planned CE and FDA authorization to market for selected neurological and musculoskeletal MR imaging applications.

The dual mode functionality allows users to switch from cutting-edge research modes to specific clinical protocols in less than ten minutes. The system provides the whole range of cutting-edge 7 Tesla research functionalities, and is based on the latest software platform syngoMR E11, identical to Siemens latest flagship 3 Tesla MRI systems, to enable consistent usability and protocol exchange.

It is the first 7 Tesla MRI scanner fully designed and manufactured by Siemens, with a completely new designed 7 Tesla magnet in its core, said Dr Bernd Ohnesorge, CEO Magnetic Resonance at Siemens Healthcare.

Now, Siemens is the only company to manufacture a complete human ultra-high field MRI system fully in-house, he added.

Magnetom Terras new actively shielded magnet is the lightest 7Tesla whole body magnet in the world“ 50 percent lighter than previous actively shielded 7 Tesla magnet generations. This is the result of a multi-year engineering project at Siemens Magnet Technologies in Oxford, capitalizing on the long-term experience of the team in the design and manufacturing of state-of-the-art 3 Tesla magnets for clinical use. As a result, with Magnetom Terra, siting of a 7 Tesla MRI system becomes much easier and its location in a clinical environment becomes feasible. Combined with the Zero Helium boil-off technology, Magnetom Terra improves the lifecycle costs of ultra-high field MRI.

Magnetom Terra increases the potential for translating cutting-edge research capabilities into future clinical application “for anatomical, functional or metabolic MR imaging. This specially designed 7Tesla technology makes this possible by offering: Up to eight channels parallel transmit technology for selective excitation and higher homogeneity in challenging body regions such as cardiac and abdominal; up to 64 receive channels for higher coil density in the field of view to achieve higher acceleration factors, higher signal-to-noise ratio and higher spatial resolution, and a better coverage of the body regions of interest; and high gradient strength of up to 80 millitesla per meter (mT/m) and a fast gradient switching rate of up to 200 Tesla per meter per second (T/m/s) for advanced studies with diffusion and functional MR imaging.

For specific clinical areas, Magnetom Terra is prepared for future clinical use with planned CE and FDA authorization to market of the system and the corresponding local coils: Getting better insights into the musculoskeletal system through unprecedented high isotropic spatial resolution of 0.2 mm; imaging brain tumors and irregularities in the brains metabolic processes; and visualizing neurodegenerative diseases such as Alzheimers disease, epilepsy, schizophrenia and multiple sclerosis.

Based on our long-standing experience and the largest innovation network in human ultra-high field MRI, Siemens is committed to further grow the foot print of 7TeslaMRI in research and clinical application, explained Dr Bernd Ohnesorge. I am confident that our Magnetom Terra will help explore new territories in MRI research and at the same time its the worlds first 7 Tesla scanner designed for clinical use.
