Proceedings Article
Non-rigid registration for stained histological sections of atherosclerotic arteries
TL;DR: This proceedings presents a novel hierarchical non-rigid registration algorithm able to align images, which contain small image artifacts, and can be applied to various multi-contrast elastic registration problems in medical imaging.
Journal ArticleDOI
Differences in Collagen Fiber Diameter and Waviness between Healthy and Aneurysmal Abdominal Aortas
TL;DR: Methods are being developed in order to efficiently determine the waviness, that is, tortuosity and amplitude, as well as the diameter, orientation, and dispersion of collagen fibers, and bundles in healthy and aneurysmal tissues.
Journal ArticleDOI
Numerical analyses of the interrelation between extracellular smooth muscle orientation and intracellular filament overlap in the human abdominal aorta

TL;DR: A modification of the intracellular filament structure could be used as a therapeutic approach in response to pathological vascular adaptation processes where changes in smooth muscle orientation are involved.
Journal ArticleDOI
Simulation of Damage Hysteresis in Soft Biological Tissues
TL;DR: In this paper, a new model for the softening hysteresis observed in overstretched arterial tissues and related computer simulations is proposed, in which the physiological loading domain is described by a purely elastic polyconvex anisotropic strain-energy function, which is decoupled into an isotropic part related to the non-collagenous matrix material, and into a transversely-isotropic part connected to the embedded (collagen) fibers.
