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.
