CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems use a series of X-ray images to create an image volume datasetthatcan slices or 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 souce CT), and interative reconstruction dose reduction software.
