First-order statistical speckle models improve robustness and reproducibility of contrast-enhanced ultrasound perfusion estimates
… that may be available from the first-order speckle statistics in a CEUS image. Heterogeneous vascular networks, typical of tumor-induced angiogenesis, lead to heterogeneous contrast enhancement of the imaged tumor cross-section. To address this, a linear (B-mode) processing approach was …

Laser speckle modeling for three-dimensional metrology and LADAR
… this thesis, I developed three-dimensional laser-speckle models to help in the development process of three-dimensional optical-metrology imaging systems. These models were developed to aid in the proof of concept for various three-dimensional metrology techniques. These models were then compared …

Coherent effects in wave propagation through complex media
… phase and, thus, a possibility of interference. Speckle, transmission fluctuations, wave localization, non-local correlations, and transmission eigenchannels are examples of persistent interference effects, which arise in the course of deterministic propagation. Such wave phenomena contain a …

Speckle applications for volumetric imaging of biological dynamics
Speckle is a high contrast granular pattern formed by coherent light interactions with rough surfaces or biological tissue. The speckle intensity fluctuates in space (or time) in a "random" manner and this randomness is often treated as noise in optical imaging. In another perspective, the speckle …
