Pie Medical’s advanced Caas packages are used in cathlabs worldwide, enabling, among others, precise quantitative and functional measurements. The Caas software package includes the following modules:

• Caas QCA for the analysis of coronary arteries, both in the field of straight and branched arteries (bifurcation),
• Caas LVA & RCA for left and right ventricle function analysis 
• Caas Stent Enhancer features enhanced stent visualization. The application automatically enhances the image region where the stent is deployed.  

Also, the package for heart and vascular diseases includes new and innovative products such as Caas vFFR, CaasIV-LINQ.

• Caas vFFR is a novel angio-based functional lesion assessment tool: wire and adenosine free. The Caas vFFR allows for fast and non-invasive measurement of the fractional flow reserve (vFFR). The average analysis takes 1-2 minutes. The software is eliminating the need for expensive pressure guides and/or microcatheters and adenosine. The advantage of vFFR software is the possibility of integration with most angiographs (Philips, Siemens, GE, Canon)

• Caas IV-LINQ enables the coregistration of IVUS and OCT images (regardless of the device manufacturer) with angiography images. In this way, the most precise assessment of the vascular lesion is possible, along with the accurate determination of the stent implantation site.

Caas MR Solutions is a modular solution that enables easy and fast MRI analysis of the cardiovascular system. 

• Caas MR 4D flow is specifically designed to extract relevant information from 3D phase-contrast (PC) MR images, within a few clicks. Based these phase-contrast images, two pioneering 4D Flow modules are offered to perform a complete flow analysis that can aid in reading and interpreting cardiovascular MR images and assist in planning the time and type of an intervention. These two modules include a module to analyze vessels, from the aorta up to smaller vessels in for example the kidneys (Caas MR 4D Artery), and a module to analyze the heart valves in terms of regurgitation fraction (Caas MR 4D Heart)

• Caas MR Functional Analysis assists in functional analy­sis of the heart. The endocardial and epicardial wall of the ventricle can be automatically segmented on short axis images. Long axis images can also be used for segmentation. Ejection fraction, End Diastolic (ED), and End Systolic (ES) volumes are accurately calculated. Wall results in terms of wall motion, wall thickness, and wall thickening can also be obtained.

• Caas MR Tissue Characterization includes three workflows: Viability, First-Pass Perfusion, and Tissue Mapping. Differentiate between viable and non-viable tissue using regional infarct classification based on delayed-enhanced MR images. Assess myocardial edema based on T2-weight­ed images. By combining segmental infarct and edema areas, salvageable areas in the area at risk can be identified. Analyze rest and stress perfusion image sets side by side in the first-pass perfusion workflow to determine myocardial per­fusion. Tissue mapping by discriminating between T1 and T2 tissue contrast is a unique strength of MRI. It allows the analysis of T1, T2, and T2* relaxation values. Relaxation values are translated into a color map for easy visualization of affected tissue. Visualization of T1 relaxation values is supported for look-locker and modified look-locker sequence.

• Caas MR 2D Flow enables one-click quantification of major vessel blood flow from phase-contrast MR images. Inspection of the blood flow profile throughout the cardiac cycle of aortic and pulmonary flow could help to identify a shunt, val­vular regurgitation or an aortic coarctation.
