Overview
CAAS A-Valve enables analysis of the aortic root on a 3 dimensional reconstruction. The reconstruction is based on two aortography X-ray projections. Based on this 3D reconstruction an optimal projection is calculated, to assist selection of the C-arm projection. Furthermore it is possible to perform basic measurements.
The workflow is fast and easy to use, which allows easy integration in the cathlab protocol.
Key Product Features
- Spline contour detection
- 3D reconstruction of Aortic Root
- Automatic 3D measurements
- Basic 2D measurements
Import / Export
CAAS accepts DICOM files with single and multi-frame, monoplane, biplane and rotational images.
Images for 3D quantification
For 3D quantification, the DICOM images need to be acquired with a flat-panel detector. The analysis can be based on an image pair acquired with a biplane X-ray system, or two images from a rotation run. Using two images of different projections acquired with a monoplane X-ray system is also possible.
The results can be exported as:
- DICOM secondary capture. The image with overlay and analysis report can be saved as DICOM SC.
- XML. The calculated results can be saved to XML, which can be transferred to a TXT file.
Key Benefits
- Digitally saved reports
- Several report formats
- Customizable templates
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.
Results
Optimal Projection with all cusps visible:
Based on two angiographic images, a range of optimal projections is calculated. By indicating the Right coronary cusp, a projection is calculated which shows the cusps aligned and displayed in this order: Posterior, Right and Left.
Measurements:
- Diameter of Ascending Aorta, Sinotubular Junction and Sinus of Valsalva based on 3D
- Diameter of Basal Plane based on caliper measurement
- Ostia height measurement
- Segment measurements
- Marker measurements
