New detector technology, combined with Siemens' established dual-source CT, offers reduced electronic noise for optimum low-signal imaging

Malvern, Pa. - Siemens Healthcare has announced that the SOMATOM Definition Flash dual-source computed tomography (CT) system with the new Stellar Detector - the first fully integrated detector that virtually eliminates electronic noise - has been cleared by the Food and Drug Administration (FDA) for sale and distribution in the United States. The new Stellar Detector further enhances the already outstanding SOMATOM Definition Flash CT system by delivering high spatial resolution, generating ultra-thin slices and providing an outstanding level of sharpness in CT at impressively low levels of patient radiation. With the combination of the SOMATOM Definition Flash CT system and the new Stellar Detector, even the finest image details can now be visualized. This exciting innovation is an example of Siemens' approach to delivering innovative solutions that provide maximum value to customers - primary goals of the Healthcare Sector's recently announced Agenda 2013.



Since its debut in late 2008, the SOMATOM Definition Flash dual-source CT system has distinguished itself by requiring only a fraction of the radiation dose that systems previously required to image even the smallest anatomical details.

With the addition of Siemens' TrueSignal technology - which, for the first time, integrates the electronic detector components into the photodiode to reduce power consumption - the new Stellar Detector significantly reduces electronic noise and improves the signal-to-noise ratio of CT images created by the SOMATOM Definition Flash. The electronic noise reduction capabilities would not be possible without the cutting-edge Ultra Fast Ceramics (UFC) detector material that is available across all Siemens CT scanners. The UFC advantages of high X-ray absorption, short afterglow and luminous efficiency ultimately enable efficient CT acquisition. With the Stellar Detector, noise reduction is possible from the very small to the very large - pediatric as well as bariatric patients.

"We are very excited about this breakthrough technology," said Kulin Hemani, U.S. VP of CT, Siemens Healthcare. "Bolstered by the new Stellar Detector, the SOMATOM Definition Flash CT system will enable clinicians to visualize more anatomical details at a lower dose, resulting in a more confident patient diagnosis and demonstrating Siemens' enduring commitment to our customers to deliver high levels of patient care."
