CAAS Workstation features segmentation of cardiovascular structures, 3D reconstruction of vessel segments and catheter path based on multiple angiographic images, measurement and reporting tools to facilitate the following use:
+ Calculate the dimensions of cardiovascular structures;
* Quantify stenosis in coronary and peripheral vessels;
* Quantify the motion of the left and right ventricular wall;
* Perform density measurements;
* Determine C-arm position for optimal imaging of cardiovascular structures;
* Enhance stent visualization and measure stent dimensions;
* Co-registration of angiographic X-Ray images with IVUS and OCT images.
CAAS Workstation is intended to be used by or under supervision of a cardiologist or radiologist. When the results provided by CAAS Workstation are used in a clinical setting to support diagnoses and for assistance during intervention of cardiovascular conditions, the results are explicitly not to be regarded as the sole, irrefutable basis for clinical decision making.
