Simulation of arterial stenting procedures prior to intervention allows for appropriate device selection as well as highlights potential complications. To this end, we present a framework for facilitating virtual aortic stenting from a contrast computer tomography (CT) scan. More specifically, we present a method for both lumen and outer wall segmentation(More)
In this article, we present a new approach for the automatic acquisition and cross-linking of cases from heterogeneous knowledge sources like manuals, articles, and mailing lists. The cases are destinated for a textual case-based reasoning system. We develop a case generation strategy including basic transformation processes, a shallow feature extraction,(More)
The purpose of this study was to evaluate the influence of advanced software assistance on the assessment of carotid artery stenosis; particularly, the inter-observer variability of readers with different level of experience is to be investigated. Forty patients with suspected carotid artery stenosis received head and neck dual-energy CT angiography as part(More)
Purpose The minimal-invasive or endovascular treatment of aneurysms requires the selection of an appropriate prosthesis (stent) before an intervention. A stent with wrong dimensions in length or diameter can lead to fatal outcomes for the patient: artery branches can be covered and thus can be excluded from the blood flow. The indicators for a correctly(More)
