Computed Tomography (CT)

Cardiac computed tomography CT systems use a series of X-ray images to create an image volume dataset that can be sliced or manipulated on any plane using advanced visualization software. This channel includes content on CT scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (also called dual souce or dual energy CT), and interative image reconstruction software that can reduce dose and make lower-quality CT images diagnostic.
