Overview
CAAS QCA 3D (3 dimensional Quantitative Coronary Analysis) offers 3D analysis of single and bifurcated coronary arteries.
Multiple X-ray projections are used to calculate the true geometric shape in 3D space. This eliminates foreshortening and out-of-plane magnification errors. QCA3D offers improved analysis results and a clear visualization of the geometry of difficult lesions.
Key Product Features
- Elimination of foreshortening and out-of-plane magnification errors
- Interactive 3D rendered view for assessment of shape
- Full automatic calibration: this eliminates the need for manual input
- Vessel border detection
- Quantification of lesion length and percentage stenosis in 3D
Import / Export
CAAS accepts DICOM files with single and multi-frame, monoplane and biplane images.
Images for 3D quantification
Two angiographic images are necessary. The images should differ at least 30 degrees in rotation and/or angulation and are perferably orthogonal. A flat panel detector is required.
The results can be exported as:
- DICOM secondary capture: the image with overlay and analysis report can be saved to a “what you see is what you get” report
- DICOM structured report: the calculated results can be saved to generate reports based on the analysis results
- XML: the calculated results can be saved to XML. A dedicated toolkit for transformation of XML files to TXT files will be provided.
- Stereolitography file: the 3D reconstruction can be exported for e.g. shear stress calculations
PACS
CAAS is suitable for standalone use or for low effort integration with DICOM Viewers. The viewer can be either standalone or embedded in a PACS environment which is supplied by third parties.
Command line interface
For integration with DICOM Viewers, CAAS has a command line interface which is easy to use. Within the DICOM Viewer, code must be developed to call the analysis by issuing a command line. On request, Pie Medical Imaging will provide the information on the available command line strings and how to use them.
In the viewer, the user can select images to analyze with CAAS. These images will be sent to CAAS. Additional images can be added by the DICOM Viewer in a later stage.
Licensing
The software can be licensed for a single user on a specific workstation or for multiple concurrent users over the institution’s network.
