Dual-Source Twin-Tube Architecture
The SOMATOM Definition Flash features two X-ray tubes and two detector arrays operating simultaneously: the A detector at 50 cm and the B detector at 33 cm, doubling cardiac data per rotation.
0.28-Second Gantry Rotation
A 0.28-second full gantry rotation delivers 75 ms temporal resolution, the fastest in clinical CT. Combined with twin-tube architecture, motion-sensitive cardiac imaging proceeds without sedation.
Flash Spiral High-Pitch Acquisition
Flash Spiral high-pitch acquisition reaches table speeds up to 458 mm per second with pitch up to 3.2. This mode enables sub-mSv cardiac CT and complete thorax scans in 0.6 seconds.
Sub-mSv Cardiac CT Angiography
The SOMATOM Definition Flash delivers cardiac CT angiography below 1 mSv routinely. Heart scanning is possible without beta-blockers, supporting broader patient eligibility for coronary studies.
Dual Energy Material Decomposition
Each X-ray tube operates at a different kV setting, delivering Dual Energy material decomposition for tissue characterisation, iodine quantification, virtual non-contrast imaging, and uric acid identification.
SAFIRE Iterative Reconstruction
SAFIRE Sinogram Affirmed Iterative Reconstruction reduces image noise and supports radiation dose savings. CARE Dose4D and CARE kV automatically optimise exposure parameters per patient.
78 cm Wide Gantry Bore
A 78 cm wide gantry aperture accommodates trauma, bariatric, and large-frame patients across diverse clinical scenarios. The wide bore reduces patient claustrophobia and supports flexible patient positioning.
