Dual Source Flash Spiral – for a scan speed of 4588 mm/s
Dual Source technology is the key to accelerating CT imaging. The combination of two sources, a high table feed, ultra-fast data transmission, and a gantry that can perform a full rotation in 0.28 seconds makes the SOMATOM Definition Flash truly unrivalled when it comes to scanning speed. Its temporal resolution of 75 ms comes with no sacrifices in image quality – instead, it offers remarkable benefits not only for the most dose-sensitive patients: With the Flash Spiral, dose values under 1 mSv are so frequent that they can be considered routine.
Dual Source with Stellar Detectors – for highest spatial resolution
The X-rays generated by the SOMATOM Definition Flash’s two sources are captured by two Stellar Detectors. These high-end detectors with miniaturized electronic components generate ultra-thin slices with a very high spatial resolution – enabling coronary CT angiography for very obese patients. Thanks to the high-speed Flash Spiral, they also permit scans of patients suffering from atrial fibrillation. Added technologies like Edge and TrueSignal drastically improve the Stellar Detectors’ already very good signal-to-noise ratio and deliver outstanding and homogeneous results over the entire field of view – especially when working with low signals.
Dual Energy with Selective Photon Shield – for better spectral separation
With the SOMATOM Definition Flash’s state-of-the-art technology, outstanding image quality even at low-kV levels and ultra-high speed image acquisition become routine – which opens the door to a huge potential for dose reduction. The Selective Photon Shield also blocks low-energy photons out of the high-energy x-ray spectrum and so prevents unnecessary exposure. Dose-reduction solutions like CARE kV, Adaptive Dose Shield, and X-CARE further contribute to dose efficiency. At the end of the day, it comes down to this: Compared with a conventional 120-kV scan, a Dual Source Dual Energy scan with the SOMATOM Definition Flash is dose-neutral – but provides significantly better results. All of these advantages make more clinical applications accessible for more patients.
