CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems using a series of X-ray images to create an image volume data set that can be sliced 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.

The Aquilion Prime system has an 80-slice detector, but can be upgraded in the field to a 180-slice system.
