Dual Source CT is a specific form of computed tomography (CT) which contains two x-ray tubes and corresponding detectors to generate internal images of an object.[1]

Mechanism

The Dual Source CT has two sources which are used simultaneously for scanning to create internal pictures. Since the acquisition is simultaneous, the time for the scanning is reduced.[2]

History

Dual Source CT scanners were introduced in 2005.

Advantages

Dual source Ct scanner allow fast scanning with higher temporal resolution by acquiring a full CT slice in only half a rotation. Fast imaging reduces motion blurring at high heart rates and potentially allowing for shorter breath-hold time. This is particularly useful for ill patients having difficulty holding their breath or unable to take heart-rate lowering medication.[2][3]
