Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

An example of FFR-CT imaging from Beaumont Hospital in Royal Oak, Mich. The left image shows a 3D generated image of the coronary tree from a CT scan evaluated with computational fluid dynamics to determine the FFR numbers. It shows a severe restriction of the left main artery which requires a stent to revacularize. The image on the right is a comparison with the invasive angiogram from the cath lab prior to stenting.
