Improving the diagnosis of breast cancer based on biophysical ultrasound features utilizing machine learning
Jihye Baek, Avice M. O'Connell, Kevin J. Parker
The improved diagnostic accuracy of ultrasound breast examinations remains an important goal. In this study, we propose a biophysical feature based machine learning method for brea…
A preliminary study of liver fat quantification using reported longitudinal ultrasound speed of sound and attenuation parameters
Juvenal Ormachea, Kevin J. Parker
The quantification of liver fat as a diagnostic assessment of steatosis remains an important priority for noninvasive imaging systems. We derive a framework in which the unknown fa…
Speckle Statistics of Biological Tissues in Optical Coherence Tomography
Gary R. Ge, Jannick P. Rolland, Kevin J. Parker
The speckle statistics of optical coherence tomography images of biological tissue have been studied using several historical probability density functions. A recent hypothesis imp…
Reverberant Elastography for the Elastic Characterization of Anisotropic Tissues
Luis A. Aleman-Castaneda, Fernando Zvietcovich, Kevin J. Parker
We derive closed-form solutions for reverberant elastography in anisotropic elastic media by adapting the framework used in electromagnetic theory to treat transverse isotropic mat…
Burr, Lomax, Pareto, and Logistic Distributions from Ultrasound Speckle
Kevin J. Parker, Sedigheh S. Poul
After 100 years of theoretical treatment of speckle patterns from coherent illumination, there remain some open questions about the nature of ultrasound speckle from soft vasculari…
Fine-tuning the H-scan for visualizing types of tissue scatterers
Kevin J. Parker, Jihye Baek
The H-scan approach is a matched filter methodology that aims to add information to the traditional ultrasound B-scan. The theory is based on the differences in the echoes produced…
Speckle from branching vasculature: dependence on number density
Kevin J. Parker, Sedigheh S. Poul
Recent theories examine the role of the fractal branching vasculature as a primary site of Born scattering from soft normal tissues. These derivations postulate that the first orde…
The first order statistics of backscatter from the fractal branching vasculature
Kevin J. Parker
The issue of speckle statistics from ultrasound images of soft tissues such as the liver has a long and rich history. A number of theoretical distributions, some related to random…
