RAPID CTA automatically provides clear, easy to interpret CTA maps and identifies brain regions with reduced blood vessel density.


The primary purpose of CT angiography (CTA) of the head is to visualize the cerebral arteries.

RAPID CTA automatically provides clear, easy to interpret CTA maps which include a colored overlay to identify brain regions with reduced blood vessel density. The severity of this reduction can be readily visualized by a simple, four-color-coded scale. Additionally, a 3D reconstruction of the vasculature allows the physician to rotate the image for optimal viewing of the blood vessels from multiple angles.  

The RAPID CTA image maps are immediately available to doctors via email (devoid of private health information) for viewing on any device, PACS and a web browser.  

These maps provide an intuitive and easily interpretable view of the brain vessels, helping physicians with:

  • Clinical decision making
  • Patient triage
  • Collaboration between community hospitals and specialists
  • Appropriate patient transfers to specialty centers

Introducing RAPID CTA

Learn how the fully automated RAPID CTA automatically provides clear, easy to interpret CTA maps.


The RAPID CTA module fully automates CTA processing. RAPID CTA receives standard CTA input data and removes bone structures, so the cerebral blood vessels can be clearly visualized by means of MIP images. The RAPID system can visualize the whole brain, as well as the vasculature in each separate cerebral hemisphere. Additionally, the system can quantify the presence of the contrast agent within brain regions and indicate the difference (ratio) in contrast-agent concentration between the hemispheres.

This ratio can be readily visualized by a simple, four-color-coded scale. Additionally, a 3D reconstruction of the vasculature allows the physician to rotate the image for optimal viewing of the blood vessels from multiple angles.
