Feasibility of Echocardiographic Particle Image Velocimetry for evaluation of cardiac left ventricular filling function
TL;DR: This work presents a new approach to extending the capabilities of Echo-PIV for more accurate measurement of cardiac flows for patients with poor quality recordings, by implementing a Moving Ensemble with Product of Correlation (PoC) processing scheme.
Spatial and dynamic organization of molecular structures in the cell nucleus
TL;DR: This thesis attempts to provide a better understanding of the principles that underlie the spatial dynamic organization of the cell nucleus by analyzing the dynamics of telomeres in nuclei of cells showing reduced levels of lamin expression and investigating whether telomere anchor to an inner nuclear lamina structure.

Particle Image Velocimetry: A Practical Guide
TL;DR: In this paper, the authors present a practical guide for the planning, performance and understanding of experiments employing the PIV technique, which is primarily intended for engineers, scientists and students, who already have some basic knowledge of fluid mechanics and nonintrusive optical measurement techniques.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.
