Malvern, Pa., November 24, 2008 - With the SOMATOM® Definition Flash, Siemens Healthcare (www.siemens.com/healthcare) is introducing a CT scanner that will set new standards regarding speed and dose reduction. The system requires only a fraction of the radiation dose that systems previously required to scan even the tiniest anatomical details faster than ever before. The SOMATOM Definition Flash is a new dual-source CT from Siemens, featuring two X-ray tubes that simultaneously revolve around the patient's body. The fastest scanning speed in CT (i.e., 43 cm/s) and a temporal resolution of 75 ms, enable for example complete scans of the entire chest region in just 0.6 seconds. Thus, patients are no longer required to hold their breath during the exam the way they had in the past. At the same time, the SOMATOM Definition Flash operates at an extremely reduced radiation dose. For example, a spiral heart scan can be performed with less than 1 millisievert (mSv), whereas the average effective dose required for this purpose usually ranges from 8 mSv to 40 mSv.
Siemens will present its new SOMATOM Definition Flash CT scanner at the 94th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) from November 30 to December 5 at McCormick Place (Booth #922, East Building/Lakeside Center, Hall D).
