Tissue-mimicking phantoms are very useful in the field of tissue characterization and
essential in elastography for the purpose of validating motion estimators. This study is …

Coronary atheroma develop in local sites that are widely variable among patients and are
considerably variable in their vulnerability for rupture. This article summarizes studies …

Intravascular ultrasound (IVUS) is a catheter based medical imaging technique particularly
useful for studying atherosclerotic disease. It produces cross-sectional images of blood …

The estimation of cardiovascular tissue motion from ultrasound images is a task of
considerable importance but has remained difficult in clinical practice, mainly due to the …

This paper describes a fast convolution-based methodology for simulating ultrasound
images in a 2-D/3-D sector format as typically used in cardiac ultrasound. The conventional …

A hierarchical block-matching motion tracking algorithm for strain imaging is presented.
Displacements are estimated with improved robustness and precision by utilizing a …

It is now recognized that prediction of the vulnerable coronary plaque rupture requires not
only an accurate quantification of fibrous cap thickness and necrotic core morphology but …

Non-invasive vascular elastography (NIVE) was recently introduced to characterize
mechanical properties of superficial arteries. In this paper, the feasibility of NIVE and its …

Optical flow (OF) method has been used in ultrasound elastography to estimate the strain
distribution in tissues. However the bias of strain estimation by OF has previously been …

Peak cap stress amplitude is recognized as a good indicator of vulnerable plaque (VP)
rupture. However, such stress evaluation strongly relies on a precise, but still lacking …
