Ultrasound Contrast Agent Modeling: A Review [PDF]
Ultrasound in Medicine & Biology, 2020 Ultrasound is extensively used in medical imaging, being safe and inexpensive and operating in real time. Its scope of applications has been widely broadened by the use of ultrasound contrast agents (UCAs) in the form of microscopic bubbles coated by a biocompatible shell.

Endoscopic Ultrasound, 2016 Endoscopic ultrasound (EUS) plays an important role in imaging of the mediastinum and abdominal organs. Since the introduction of US contrast agents (UCA) for transabdominal US, attempts have been made to apply contrast-enhanced US techniques also to EUS. Since 2003, specific contrast-enhanced imaging was possible using EUS. Important studies have been

Acoustic Sizing of an Ultrasound Contrast Agent
Ultrasound in Medicine & Biology, 2010 Because the properties of ultrasound contrast agent populations after administration to patients are largely unknown, methods able to study them noninvasively are required. In this study, we acoustically performed a size distribution measurement of the ultrasound contrast agent Definity(®).

Ultrasound contrast agents: resonances of coated bubbles
, 2023 The Brandaris 128 high speed camera was designed and built in order to analyze the dynamics of single oscillating contrast agent microbubbles under influence of ultrasound. In this thesis we report on our findings. First, in Ch. 2, a new model was introduced which takes into account the physical properties of a lipidmonolayer coating on a ...

Ultrasound contrast agents: bubbles drops and particles [PDF]
, 2015 The research on the medical use of microbubbles has coontinuously provided fascinating results for half a century. Investigating new agents or new uses of existing agents requires both innovative physics and ideas and extensive testing in-vitro and in vivo. The translation from the lab to the clinic is long and calls upon many specialties.

Ultrasound contrast agents : dynamics of coated bubbles [PDF]
, 2010 Contrast-enhanced ultrasound imaging relies on the nonlinear scattering of microbubbles suspended in an ultrasound contrast agent. The bubble dynamics is described by a Rayleigh-Plesset-type equation, and the success of harmonic imaging using contrast agents has always been attributed to the nonlinear behavior predicted by this equation. Contrast agent

Ultrasound contrast agents : optical and acoustical characterization [PDF]
, 2009 This thesis describes the characterization of the dynamics and the acoustic responses of single BR14 (Bracco Research S.A., Geneva, Switzerland) ultra- sound contrast agent microbubbles under the in°uence of ultrasound. In Ch. 2 of this thesis we investigate the small amplitude behavior of isolated microbubbles acoustically. To ensure that the measured

Der Radiologe, 2004
Ultrasound contrast agents consist of tiny gas bubbles encapsulated by a stabilising membrane or shell. When combined with recent contrast-specific ultrasound techniques, they provide substantial enhancement of vessels and solid organs. The clinical use and the diagnostic value of ultrasound contrast agents are in principle comparable to those of ...
