How it Works

The Advanced TVC Imaging System integrates near infrared spectroscopy (NIRS), with IVUS to provide information on both vessel structure and plaque composition, which can enable quick and informed clinical decision-making and greater confidence in determining procedural and treatment strategies.

Rapid and Automated Vessel Characterization

In a single catheter pullback, the Advanced TVC Imaging System provides physicians with a high resolution IVUS image that clearly displays key structural details of the lesion, including its location, length, and degree of stenosis, in addition to assessing stent placement and expansion.

At the same time, the system performs spectroscopic analysis of the artery and plaque to produce a Chemogram™, a map that indicates the location of lipid-core plaques (LCP) of interest and quantifies the lipid core burden of the artery.

  • On the Chemogram, LCPs are visualized as bright yellow and are co-registered with the grayscale IVUS image of the coronary artery.


Co-Registered Image for Real-Time Decision-Making

A co-registered image, called a TVC Composite™ Image, appears immediately on both the high-definition physician and operator monitors.

Integrating and co-registering the Chemogram with IVUS provides critical information to interventional cardiologists during the cardiac catheterization procedure.
