Siemens Definition DS

Description

Overview

The Siemens SOMATOM Definition DS revolutionized diagnostic imaging by introducing the world’s first dual-source CT architecture. By placing two complete X-ray sources and detector systems on a single rotating gantry, the system cuts the required angular data collection time in half. This breakthrough overcomes the physical limitations of single-tube rotation speeds, making motion-free cardiac imaging routine.

Designed for high-acuity hospitals and specialized cardiology centers, the Definition DS handles complex diagnostic scenarios—such as high heart rates, severe arrhythmias, and uncooperative trauma patients—without requiring pre-medication like beta-blockers. Furthermore, its native Dual-Energy capability allows clinicians to scan at two different energy spectra simultaneously, revealing hidden tissue characteristics, bone removal maps, and contrast agent concentrations without a dose penalty.

Key Features & Advanced Technologies

• Dual-Source Geometry: Utilizes two pairs of X-ray tubes and UFC (Ultra Fast Ceramic) detector arrays positioned at a 90-degree offset, acquiring comprehensive volumetric datasets at twice the speed of single-source systems.

• 83 ms Temporal Resolution: Freezes fast-moving coronary arteries completely. Multisector reconstruction algorithms can further enhance temporal clarity down to 42 ms.

• Simultaneous Dual-Energy Scanning: Acquires low- and high-kV data sets simultaneously from the same spatial location and phase, enabling precise virtual non-contrast images, gout differentiation, and kidney stone characterization.

• Twin STRATON™ X-Ray Tubes: Heavy-duty, direct-anode liquid-cooled tubes engineered with zero-heat-storage design principles, supplying continuous high-mA output during demanding multi-phase acquisitions.

• 160 kW High-Power Generator Reserve: Combines dual 80 kW generators to guarantee stable, robust photon output across large bariatric patients and dense anatomical regions.

• Extended 78 cm Gantry Bore: Provides wider physical clearance to accommodate claustrophobic patients, trauma frames, and interventional positioning devices comfortably.
