Overview
CAAS QCA for Research (Quantitative Coronary Analysis) has specific additional functionality for both single vessel and bifurcation analysis. For example, stent analysis models, which feature quick comparison of implanted (bifurcation) stents in pre-, post- and follow-up studies.
Key Product Features:
- Various methods for calibration; catheter, sphere, manual or automatically calculated based on geometric information
- Vessel border detection
- Easy contour edits
- Automatic and user defined reconstruction of the healthy vessel shape
- Quantification of lesion length and percentage stenosis
- Drug Eluting Stent analysis: evaluation of restenosis and edge effects with a dedicated segment model
- User Defined Subsegment analysis: divide the vessel in multiple sub segments
- Independent evaluation of multiple segments within one vessel part
- Dedicated models for bifurcation analysis: 6 and 11 segments
Import / Export
CAAS accepts DICOM files with single and multi-frame, monoplane and biplane images.
The results can be exported as:
- DICOM secondary capture. The image with overlay and analysis report can be saved as DICOM SC. This results in a “what you see is what you get” report.
- DICOM structured report. The calculated results can be saved as DICOM SR. This can be used to generate reports based on the analysis results
- XML. The calculated results can be saved to XML. Pie Medical Imaging provides a dedicated toolkit for transformation of XML files to TXT files.
Key Benefits
- Digitally saved reports
- Several report formats
- Customizable templates
Licensing
The software can be licensed for a single user on a specific workstation or for multiple concurrent users over the institution’s network.
Results
The report pages can be accessed at any time during the analysis. All graphs and tables matching your analysis will be displayed.
Dedicated segment models
Single vessel results can be displayed in the drug eluting stent model. It is also possible to define your own segments. In case the bifurcation option is available, results can be displayed in dedicated 6- and 11-segment models.
Key Results:
- Minimum luminal diameter (MLD)
- Reference diameter
- % Diameter stenosis
- Length of the stenotic segment
- Area at MLD
- % Area stenosis at MLD
- Reference area
- Volume stenotic segment
- Plaque area, volume and symmetry
- Bifurcation angles
