FDA clears Somatom Definition CT scanner
Siemens Medical Solutions USA has received FDA 510(k) market clearance for the Somatom Definition AS, an adaptive CT scanner.

The Medical University of South Carolina (MUSC) in Charleston is one of the first facilities to install the scanner, adding to the Somatom Definition Dual Source installed in September 2006, according to Siemens.

The Somatom Definition AS adapts to any patient and to the user’s space, for complete dose protection, for new dimensions, according to the company.

Seimens said it offers information of up to 27 cm. In the case of a stroke, physicians can use whole-organ perfusion imaging not only for a small part of the brain, but for all of it.

“The Somatom Definition AS goes beyond slices and detector rows to addresses the overall versatility and usefulness of a CT scanner,” said Joseph Schoepf, MD, associate professor of radiology and cardiology, and director of CT research and development at MUSC. “It truly allows you to adapt the CT scanning to your individual patients.”

The Somatom Definition AS comes in multiple configurations, tailored to a hospital’s workflow and clinical needs. The technology couples multiple components: a large-volume coverage area with a 200-cm scan range and up to 300 msec rotation time; 78-cm gantry bore; and the ability to add a high-capacity 660-pound patient table, according to Siemens.

The company said that the Definition AS is available in 40-slice, 64-slice and 128-slice configurations, and can be field upgraded to other configurations.
