CAAS QVA 3D

Overview

CAAS QVA 3D (3 dimensional Quantitative Vascular Analysis) offers fast and intuitive analysis of peripheral vessels such as the abdominal aorta and the carotid, renal, iliac and femoral arteries. CAAS QVA 3D features single vessel analysis including full automatic calibration, vessel border detection and quantification of severity of stenosis according to its true 3D geometric shape.

Key Product Features:

Elimination of foreshortening and out-of-plane magnification errors
Interactive 3D rendered view for assessment of shape
Full automatic calibration: reconstruction in 3D space allows for an optimal automatic calculation of the pixel size for each position of the artery. This eliminates the need for manual input
Vessel border detection based on novel algorithms.
Easy contour edits
Automatic and user defined reconstruction of the healthy vessel shape according to its true 3D geometric shape
Quantification of lesion length and percentage stenosis.

Import / Export

CAAS accepts DICOM files with single and multi-frame, monoplane and biplane 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. 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. 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.
