Siemens Introduces First Web-Enabled CT; SOMATOM Definition CT Receives FDA Approval for First Six Dual Energy Applications
FDA OK’s Use of Spiral Dual Energy in World’s First Dual Source CT; Differing Energies Enable Tissue Characterization, Bone Removal
Chicago, Nov 28, 2006 - Siemens Medical Solutions today announced it has received 510(k) approval from the U.S. Food and Drug Administration (FDA) for the first of many syngo® Dual Energy applications for the SOMATOM® Definition - the world’s first and only dual source computed tomography (DSCT) system. The announcement was made at the 92nd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), at which Siemens Medical Solutions is exhibiting in booth #4129 from Nov. 26 to Dec. 1.
The FDA clearance allows for use of SOMATOM Definition’s two X-ray sources at two different energy levels in simultaneous spiral scanning. This enables clinicians to explore various scenarios for tissue characterization and paves the way for dual energy to become part of the standard daily clinical routine.
“Siemens SOMATOM Definition redefined CT imaging and is once again pushing the clinical boundaries to a higher level with expanded capabilities that turn the most complex examinations into an easy CT routine,” said Bernd Montag, president, CT Division, Siemens Medical Solutions. “The expanded use of the Definition solidifies its value as a complete and comprehensive solution, not only for large hospitals, but also for diagnostic imaging centers and community hospitals.”
Earlier approaches in dual energy CT created two subsequent but separate scans at different tube voltages, but failed to seamlessly align the imaged anatomy. SOMATOM Definition overcomes this limitation by permitting the use of two sources at two different kilovolt (kV) levels simultaneously. The result are two spiral data sets acquired in a single scan providing diverse information, which enables clinicians to differentiate, characterize, isolate, and distinguish the imaged tissue and material.
The Definition now provides even more unique clinical advantages, including direct subtraction of bone in complicated anatomical regions; virtual un-enhanced liver images without multiple scans; evaluation of lung perfusion defects; visualization of cartilage, tendon and ligaments; and, differentiation between hard plaques and contrast agents.
The SOMATOM Definition - Faster Than Every Beating Heart
With the introduction of the SOMATOM Definition in 2005, Siemens launched a new era in CT imaging. The Definition is the world’s first dual-source CT scanner, enabling CT acquisition with two X-ray sources and two detectors, rather than the single X-ray source and detector configuration commonly available in standard systems.
The SOMATOM Definition features the industry’s highest true temporal resolution of 83 milliseconds, allowing the system to image the most clinically challenging cardiac patients without beta blockers and independent of heart rate. This enables the reliable acquisition of clear cardiac images while avoiding the issues inherent in multi-segment reconstruction.
The solution also delivers images without motion artifacts, displaying the finest anatomical details with crystal clarity. The SOMATOM Definition provides clinical research professionals, physicians, hospitals and outpatients clinics with advanced radiographic applications including acute care, cardiology, neurology and oncology.
More than 15,000 Beta Blocker-free Cardiac Scans Performed
Currently, the Definition is installed at more than 100 clinical facilities - including leading research facilities, diagnostic imaging centers and community hospitals - and should exceed 150 sites by year’s end. More than 15,000 cardiac patients have been scanned with the Definition without the need for beta blockers, demonstrating its value in cardiac CT by enabling physicians to confidently perform cardiac examinations without compromise.
“The value of the Definition is being discovered across a wide spectrum of diagnostic facilities, from the largest systems and research institutions to smaller community hospitals,” said Scott Goodwin, U.S. vice president, CT Division, Siemens Medical Solutions. “For the patient, that means wider access to a high level of diagnostic care.”
Siemens Sensation Web Selection: World’s First Web-Enabled CT
To address the demands of today’s 64-slice CT workflow, Siemens is introducing SOMATOM Sensation Web Selection, the world’s first Web-enabled CT. By providing instant accessibility of 3D volume data anytime, anywhere, this solution turns any (Internet-connected, diagnostic-quality) personal computer into a thin-client clinical workstation. For the physician it means more information and a faster diagnosis for better patient care.
SOMATOM Sensation Web Selection brings together an excellent combination of high-end CT imaging and post-processing capabilities. For example, Cardiac CT benefits from the industry’s fastest 0.33-second temporal resolution and Siemens unique syngo Circulation software. In addition, the system offers z-Ultra High Resolution, enabling the highest available spatial resolution of 0.24 millimeters for imaging of fine anatomical detail.
