System Features
General
This new generation of dual- source CT scanners, featuring two X-ray tubes and two detectors, will provide a genuine innovation boost to dual-source technology. The enormous speed of the SOMATOM Definition Flash offers decisive advantages, especially regarding examinations of moving structures, such as the thorax and the heart. The gantry (i.e., the X-ray detector system surrounding the bore) rotates about its own axis in just 0.28 s. It is this extraordinary rotational speed that enables a scan speed never before attained in CT (i.e., up to 43 cm per second) and temporal resolution of 75 milliseconds.
Special Features
Split-second thorax
Scanning the thorax incl. the heart needs 0.6 s, taking the burden of breath-holding off the patient and allowing functional imaging for body regions up to 48 cm.
Sub-mSv heart
Temporal resolution of 75 ms and scan speed of up to 43 cm/s make heart-scanning without beta-blockers possible and for the first time breath-hold optional with dose levels below 1 mSv.
Single dose Dual Energy
With the Selective Photon Shield Dual Energy scans are now dose neutral. Together with dramatically increased energy separation and a wide range of FDA-cleared applications, it’s now perfect for routine clinical use.
Organ-sensitive dose protection
The SOMATOM Definition Flash prevents clinically irrelevant dose for spiral examinations and introduces for the first time organ-sensitive dose protection.

Somatom Definition Flash dual-source CT
Hot
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. The new CT scanner will be available for sale in the first quarter of 2009.

i had opportunity to work on somatom definition.
this has wonderful technology ,good resolution and 3-d reconstruction, excellent for coronary artery studies
