AAA Analyser - A4clinics™

Reliable diagnoses need excellent diagnostic systems. If you think diagnosis, think VASCOPS.


A4clinics™ - A novel diagnostic system for aortic aneurysms, designed for in-depth analysis of patient-specific vascular formations. The system integrates the latest technology and scientific findings; it is the perfect tool to assist aneurysm screening. A4clinics™ is entirely feasible to analyze realistic models on standard PCs


The user interfaces are easily accessible to gain optimally from the software with a minimum on training. A4clinics™ is designed for users without an engineering background and offers support and trainings options.

A4clinics™ Peak Wall Rupture Risk- PWRR™

Features & Benefits

The patented* functionality of A4clinics™ includes: import of patient data, detection of vascular bodies, meshing and biomechanical analysis.

Import of patient data. A4clinics™ requests data related to arterial pressure, age, gender and family history together with the Computer Tomography CT images of the individual patient.

The CT DICOM images can be loaded either through direct connection to your hospital Picture Archive Communication System (PACS) or CD-ROM / DVD or USB stick.

Semi automatic detection of vascular bodies. In order to calculate the rupture risk of the AAA, A4clinics™ segments the aneurysm's lumen, thrombus and wall from the CT images.

This active segmentation tool ensures that stress artifacts during the biomechanical analysis stage are eliminated.

Biomechanical analysis. The biomechanical analysis integrates recent scientific findings with the patient-specific data and calculates a patient-specificPeak Wall Rupture Risk (PWRR), i.e. a proven AAA rupture risk index.

The final result is clearly displayed and can be blended together with the anatomical CT data, providing a valuable 3D overview of area's at high risk of rupture.

Service & Support

VASCOPS is committed to provide excellent support for their customers and has a wide variety of training and support tools available online. Your purchase of the A4clinics™ software comes standard with a bronze support contract which can be extended by additional services like installation, training, support to even provided consultancy for specific case analysis.
Installation services. As standard the purchased A4clinics™ software can be downloaded from our website and automatic license activation is all possible using the internet connection. However we are pleased to offer additional installation services which can vary from remote help & configuration (silver support level) to local installation of your existing PC (gold support level).
Training. A standard range of tutorials alongside a manual how to use is included in the bronze support package. Additional we are able to train your department using either private web cast sessions or personal training within your hospital.
Please tell us your personal training needs for A4clinics™ as we would like to accommodate this in a cost efficient manner.
Support. Although A4clinics™ is using an internet connection to obtain automatic updates the standard support package (bronze) can be extended with a higher level support (silver or gold) tailored to your specific support requirements.
Our highly trained support desk can be contacted to address any support issues which you might have during installation, updates & upgrades or any technical question.

For gold level customers we even go one step further by allocating our research staff for consultation on your specific AAA case and any latest developments in biomechanics and image reconstructions which might be helpful for your cases.
