The document discusses the benefits of Siemens' SOMATOM Definition Dual Source CT scanner, which uses two X-ray sources and detectors to acquire imaging data twice as fast as single source CT scanners. This allows motion-free cardiac imaging of all patients regardless of heart rate or condition without needing beta blockers. The Dual Source CT technology also enables a variety of new clinical applications like plaque characterization, in-stent imaging, and dual energy scanning.
