Device-Induced Thrombus Formation in Cerebral Aneurysms: Linking Patient-Specific Clot Modeling and Functional Occlusion to Virtual Angiographic Assessment
Fabian Holzberger, Struan Hume, Markus Muhr +2
Endovascular treatment of cerebral aneurysms aims to achieve functional occlusion and isolation of the aneurysm sac from bloodflow. In clinical practice, treatment success is asses…
Numerical simulation of individual coil placement -- A proof-of-concept study for the prediction of recurrence after aneurysm coiling
Julian Schwarting, Fabian Holzberger, Markus Muhr +4
Rupture of intracranial aneurysms results in severe subarachnoidal hemorrhage, which is associated with high morbidity and mortality. Neurointerventional occlusion of the aneurysm…
Numerical simulation of endovascular treatment options for cerebral aneurysms
Martin Frank, Fabian Holzberger, Medeea Horvat +7
Predicting the long-term success of endovascular interventions in the clinical management of cerebral aneurysms requires detailed insight into the patient-specific physiological co…
A Comprehensive Numerical Approach to Coil Placement in Cerebral Aneurysms: Mathematical Modeling and In Silico Occlusion Classification
Fabian Holzberger, Markus Muhr, Barbara Wohlmuth
Endovascular coil embolization is one of the primary treatment techniques for cerebral aneurysms. Although it is a well established and minimally invasive method, it bears the risk…
Elasto-acoustic modelling and simulation for the seismic response of structures: The case of the Tahtalı dam in the 2020 İzmir earthquake
Ilario Mazzieri, Markus Muhr, Marco Stupazzini +1
As a mean to assess the risk dam structures are exposed to during earthquakes, we employ an abstract mathematical, three dimensional, elasto-acoustic coupled wave-propagation model…
A discontinuous Galerkin coupling for nonlinear elasto-acoustics
Markus Muhr, Vanja Nikolić, Barbara Wohlmuth
Inspired by medical applications of high-intensity ultrasound, we study a coupled elasto-acoustic problem with general acoustic nonlinearities of quadratic type as they arise, for…
A high-order discontinuous Galerkin method for nonlinear sound waves
Paola. F. Antonietti, Ilario Mazzieri, Markus Muhr +2
We propose a high-order discontinuous Galerkin scheme for nonlinear acoustic waves on polytopic meshes. To model sound propagation with and without losses, we use Westervelt's nonl…
Self-adaptive absorbing boundary conditions for quasilinear acoustic wave propagation
Markus Muhr, Vanja Nikolić, Barbara Wohlmuth
We propose a self-adaptive absorbing technique for quasilinear ultrasound waves in two- and three-dimensional computational domains. As a model for the nonlinear ultrasound propaga…
Isogeometric shape optimization for nonlinear ultrasound focusing
Markus Muhr, Vanja Nikolić, Barbara Wohlmuth +1
The goal of this work is to improve focusing of high-intensity ultrasound by modifying the geometry of acoustic lenses through shape optimization. The shape optimization problem is…
