Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: In this study we present a design of biotechnical system for endovascular treatment of aneurysms using mathematical modeling of hemodynamics and endoscopic optical coherence tomography. The approaches for obtaining patient-specific mechanical properties of the vessel wall and individualized mathematical modeling of the cerebral blood flow are described in detail. The proposed biotechnical system takes into account the individual biomechanical properties of the cerebral artery wall measured in vivo and has a potential to be used in clinical practice for improved patient-specific evaluation of hemodynamics in the cerebral artery with an aneurysm before and after the endovascular treatment
