Stress analysis in atherosclerotic arteries: The influence of heterogeneity

Atherosclerosis is a progressive arterial disease in which fatty tissue accumulates in the arterial wall. Due to this lipid uptake, the artery thickens and can eventually rupture, causing the lipids to flow into the bloodstream and form blood clots. If this happens in the carotid arteries, which supply the head with oxygenated blood, a stroke...

Needle deflection in tissue

Introduction: One of the factors that contribute to the total needle-targeting error in medical procedures is needle deflection, which can lead to e.g. hemorrhage, prolonged intervention time and decreased treatment efficiency. This deflection can be defined as the deviation of the needle from its suspected straight insertion path. In this study...
