Optimal C-arm positioning for aortic interventions

Abstract

Due to the continuous integration of innovative interventional imaging modalities into vascular surgery rooms, there is an urgent need for computer assisted interaction and visualization solutions that support the smooth integration of technological solutions within the surgical workflow. In this paper, we introduce a new paradigm for optimalview controlled maneuvering of Angiographic C-arms during thoracic endovascular aortic repair (TEVAR). This allows the semi-automatic pre-computation of well-defined anatomy-related optimal views based on pre-operative 3D image data and automatic interventional positioning of the imaging device relative to the patient’s anatomy through inverse kinematics and CT to patient registration. Together with our clinical partners, we have evaluated the new technique using 5 patient datasets and are able to show promising results.
