Rapid CTA

Automatic Identification of Blood Vessel Density Asymmetry for More Accurate Decisions in Patient Care

Rapid CTA automatically processes CT scans to quickly deliver clear CT angiography images that identify regions of asymmetry in blood vessel density for faster, more accurate patient care decisions.

RapidCTA
AUTOMATIC INFORMATIVE. CLEAR.

Clear, Informative Results for Better Decision Making

Rapid CTA quickly and automatically removes bone and non-vascular tissue and creates 3D vascular reconstructions to deliver clear views of the brain and easy-to-interpret color-coded results that identify regions of asymmetry in blood vessel density.

Rapid CTA 2D Output

Rapid CTA maps 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.

Rapid CTA 3D Rotational Output

A 3D reconstruction of the vasculature allows the physicians to rotate the image for optimal viewing of blood vessels from multiple angles.

Good Collaterals

Patients with occlusions of the middle cerebral or internal carotid artery typically have a > 10% reduction in blood vessel density. A blue or green overlay identifies a mild reduction in blood vessel density.

Poor Collaterals

The Rapid CTA map above shows a patient with a middle cerebral artery occlusion and poor collaterals, resulting in a severe reduction in vessel density and is identified in red.

Rapid CTA Coronal Views

Rapid CTA results include coronal views of the vasculature.

Rapid CTA Sagittal Views

Rapid CTA provides a sagittal view for comprehensive viewing of the brain vessels.

KEY BENEFITS

Designed to Help Improve Patient Outcomes, Rapid CTA is:

AUTOMATIC

Upon receipt of a scan, Rapid CTA automatically removes bone and non-vascular tissue to generate MIP images of cerebral blood vessels and identifies regions of asymmetry in blood vessel density.

INFORMATIVE

In addition to delivering coronal, sagittal, and axial views of the brain and source images, Rapid CTA creates 3D vascular reconstructions that can be rotated for optimal viewing of blood vessels.

Clear

Rapid CTA employs a color-coded overlay for fast, easy-to-interpret identification of regions of asymmetry in blood vessel density.
