Ultrasound provides a valuable tool for medical diagnosis offering real-time imaging with
excellent spatial resolution and low cost. The advent of microbubble contrast agents has …

Microbubbles and cavitation are playing an increasingly significant role in both diagnostic
and therapeutic applications of ultrasound. Microbubble ultrasound contrast agents have …

Contrast-enhanced ultrasound (CEUS) with microbubble contrast agents is a new imaging
technique for quantifying tissue perfusion. CEUS presents several advantages over other …

The bifurcation structure of the oscillations of ultrasound contrast agents (UCAs) was studied
as a function of the driving pressure for excitation frequencies that were determined using …

The renal medullary microcirculation is a distinctive arrangement of blood vessels that serve
multiple functions in the renal medulla. This article begins with a description of the unique …

This paper investigates two types of nonlinear propagation and their effects on image
intensity and contrast-to-tissue ratio (CTR) in contrast ultrasound images. Previous studies …

Historically, tools to assess renal function have been developed to investigate the
physiology of the kidney in an experimental setting, and certain of these techniques have …

A new signal model and processing method for quantitative ultrasound perfusion analysis is
presented, called bolus-and-burst. The method has the potential to provide absolute values …

Simple Summary Contrast-enhanced ultrasound is a technique which enables assessment
of tissue blood flow by injecting gas-filled micro-bubbles in the bloodstream. As a diagnostic …

Radiological techniques are now able to provide morphologic, functional, and structural
information relative to kidney diseases. Many of these approaches have been proposed …
