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 ...

The Elastic Constant of Tissue in the Body Estimated from Computerized Tomography and Ultrasonography : Theoretical Analysis [PDF]

, 1981
1981-11This paper describes a method for calculating the elastic constant of tissue. Length measurements obtained from Ultrasonograms (US) are different from the results obtained from Computerized Tomograms (CT) when the velocity of sound is compared to ...

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.
