Image Fusion Angio

Color Intensity Projection (CIP) Images

Background

CIP image sequences are automatically generated for each fused DSA image upon leaving the application.

How to Interpret CIP Images

CIP images provide temporal information on blood flow from a number of sequential DSA images. The arrival time of contrast agent at a given location is color coded into a single composite image. The color of each pixel indicates the time that contrast arrived at that location. Structures with high contrast attenuation (e.g., larger vessels and vascular lesions) appear brighter.



Here is a DSA image at the beginning of the sequence and the corresponding CIP image .

  • Red and orange: Areas that already received contrast agent.
  • Yellow and green: Areas that are currently receiving contrast agent. These are the areas with the highest concentration of contrast agent in a given frame.
  • Turquoise and blue: Areas that have not yet received contrast agent.
