4D Computational Modeling of Basilar Artery for Aneurysm Study - In Vivo Deformation of the Human Basilar Artery - Ann Biomed Eng 2024 Sep
First to quantify in vivo neurovascular wall strains of the human basilar artery over the cardiac cycle.
Demonstrated 4D computational model construction from 4D biomedical data, enabling detailed local deformation analysis for patient-specific aneurysm risk assessment.
Representative image of B-spline surface fitting of basilar artery. The control points (white dots) and the centerline (red curve) are illustrated
Representative stretch images where stretches are calculated.
(a) FEA results for areal change and (b) B-spline-based analysis results for local areal change
