QuantWeb QCA3D / syngo IZ3D

The 3-dimensional quantification tool for coronary arteries

QuantWeb QCA3D / syngo IZ3D  offers automated detection and 3D analysis of single and bifurcated coronary arteries from angiographic X-ray projection images. Out-of-plane magnification and foreshortening errors are minimized by calculating true geometric shape in 3D space from two or more 2D X-ray projections.



Features & Benefits

An interactive rendered view of the coronary artery in 3D helps you visualize and assess the geometry. QuantWeb QCA3D / syngo IZ3D offers analysis of difficult lesions and segment anatomy.


  • Results are validated to be accurate and reproducible
  • Automatic calibration, no catheter calibration required
  • Interactive 3D rendered view for assessment of shape
  • Fast and user friendly
  • For scientific studies and patient care

A clinical study conducted by:

- Biomedical Engineering, Erasmus MC, Rotterdam,
- The Netherlands Interventional Cardiology, Erasmus MC, Rotterdam,
- The Netherlands LKEB, Department of Radiology, Leiden University Medical Center, Leiden,
- The Netherlands Inter Cardiologic Institute The Netherlands, Utrecht, The Netherlands

compares the results of syngo IZ3D (based on CAAS QCA-3D, Pie Medical) against ANGUS intravascular ultrasound and reports a high correlation of the 3D geometry and the vessel lumen between both methods.

The statements by Siemens Healthineers customers described herein are based on results that were achieved in the customer's unique setting. Since there is no "typical" hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption) there can be no guarantee that other customers will achieve the same results.
