Quantification of Atherosclerotic Plaque Elasticity Using Ultrasonic Texture Matching

IEEE Access, 2020
The composition of an atherosclerotic plaque is a major determinant of its vulnerability, i.e. proneness to rupture. This paper proposes an ultrasonic texture matching method, which is shown to reflect the distribution of elastic modulus and is a ...

Elastic transformation of histological slices allows precise co-registration with microCT data sets for a refined virtual histology approach

Scientific Reports, 2021
Although X-ray based 3D virtual histology is an emerging tool for the analysis of biological tissue, it falls short in terms of specificity when compared to conventional histology.

Extracellular matrix in ascending aortic aneurysms and dissections - What we learn from decellularization and scanning electron microscopy.

PLoS ONE, 2019
Pathological impairment of elastic fiber and other extracellular matrix (ECM) components are described for the aortic media of ascending thoracic aortic aneurysms (aTAA) but the exact pathological impairment of the structure and its degree still needs ...
