Experimental acoustic characterization of an endoskeletal antibubble contrast agent: First results [PDF]
Medical Physics, 2021 AbstractPurposeAn antibubble is an encapsulated gas bubble with an incompressible inclusion inside the gas phase. Current‐generation ultrasound contrast agents are bubble‐based: they contain encapsulated gas bubbles with no inclusions. The objective of this work is to determine the linear and nonlinear responses of an antibubble contrast agent in ...

Acoustic response from adherent targeted contrast agents [PDF]
The Journal of the Acoustical Society of America, 2006 In ultrasonic molecular imaging, encapsulated micron-sized gas bubbles are tethered to a blood vessel wall by targeting ligands. A challenging problem is to detect the echoes from adherent microbubbles and distinguish them from echoes from nonadherent agents and tissue.

Acoustically-Stimulated Nanobubbles: Opportunities in Medical Ultrasound Imaging and Therapy
Frontiers in Physics, 2021 Medical ultrasound is one of the most widely used imaging modalities worldwide. Microbubbles, typically ~1–8 μm in diameter, are ultrasound contrast agents confined to the vasculature due to their size.

First experiments with carbon black pigment dispersion acting as a Janus ultrasound contrast agent
BIO Integration, 2023 Background: Theranostic ultrasound contrast agents comprise a therapeutic component whose controlled release is triggered by an ultrasound pulse. However, once the therapeutic component has been released from an ultrasound contrast agent microbubble, its

Theoretical prediction of the scattering of spherical bubble clusters under ultrasonic excitation
Ultrasonics Sonochemistry, 2023 Due to the nonlinear vibration of ultrasound contrast agent bubbles, a nonlinear scattered sound field will be generated when bubbles are driven by ultrasound. A bubble cluster consists of numerous bubbles gathering in a spherical space.
