Zusammenfassung

For the characterization of intracranial aneurysms, morphological and hemodynamic parameters provide valuable information. To evaluate these quantities, the separation of the aneurysm from its parent vessel is required by defining a neck curve and the corresponding ostium. A fundamental problem of this concept is the missing ground truth. Recent studies report strong variations for this procedure between medical experts yielding increased interobserver variability for subsequent evaluations. To make further steps towards consensus, we present a web application solution, combining a client based on HTML and JavaScript and a server part utilizing PHP and the Matlab Runtime environment. Within this study, participants are requested to identify the neck curve of five virtual aneurysm models. Furthermore, they can manipulate the ostium surface to model the original parent artery. Our application is now available online and easily accessible for medical experts just requiring an internet browser.
