Technical specifications for multi-detector row computed tomography (CT) scanners from different manufacturers were very similar until the introduction of 64-slice scanners but then began to diverge with fundamental differences in the number of X-ray sources, detector geometry, gantry rotation time, and reconstruction algorithms. These hardware and software advancements were largely driven by clinical requirements for cardiac CT. This article provides an overview of technologies available on state-of-the-art CT systems and the clinical needs they seek to address.
