Mayo Clinic in Rochester, MN and NYU Medical Center (NYUMC) in New York City are the first facilities in the U.S. to install Siemens’ SOMATOM Definition, a dual-source computed tomography (CT) system, which for the first time incorporates two X-ray sources and two detectors in a single scanner. To date, 10 Definition scanners have been installed worldwide.
With the ability to capture data twice as fast as any existing multi-slice CT technology, the Definition can deliver motion-free cardiac images, independent of heart rate. The Definition also has power reserve and dual-energy capabilities not previously available with any other CT system, unlocking new possibilities in emergency radiology.
The systems are being used for cardiac and vascular exams, as well as research into new applications for CT imaging. Mayo Clinic has already begun research studies exploring the system's potential in using dual X-ray energies to better differentiate tissue in various parts of the body.
