First Dual-Source CT System Brings More Innovative Diagnostics to the
Market
MALVERN, Pa., March 10 /PRNewswire/ -- Encouraged by the outstanding marketing success of the worldwide first Dual-Source computed tomography (CT) system, the SOMATOM(R) Definition, Siemens Healthcare (http://www.siemens.com/healthcare) announces the 510(k) market clearance of four new applications aimed at simplifying the diagnosis of diseases of the heart, brain, lungs, and extremity joints. With a dual X-ray tube and dual-detector design, the SOMATOM Definition routinely provides images at twice the temporal resolution, twice the speed, and twice the power of single-source systems. Siemens announced the new applications at ECR 2008, currently being held in Vienna.

The SOMATOM Definition acquires images of outstanding quality and detail even of hearts with a high heart rate or irregular heartbeat -- at only half the dose of previous Siemens systems. The two X-ray tubes provide the system with features previously not existing in diagnostic imaging. This includes the possibility of, simultaneously, operating the X-ray tubes at different voltage levels (dual energy, or DE) in a single scan so that two data records with different patient information are generated, thereby displaying tissue and fluids and facilitating the distinction of vessels, bones, and soft tissue.
"The SOMATOM Definition moves CT to an entirely new dimension of
diagnostic sensitivity where contrast in the image is not merely limited to
x-ray attenuation differences, but may include elements of functional and
tissue characterization. This additional information may be used to improve
diagnostic outcomes and to simplify complex workflows," expla
