Improvement of Detection Sensitivity of Microbubbles as Sensors to Detect Ambient Pressure
Sensors, 2018 Microbubbles are considered a promising tool for noninvasive estimation of local blood pressure. It is reported that the subharmonic scattering amplitude of microbubbles decreases by 9 to 12 dB when immersed in the media under an ambient pressure ...

Analysis of the Uncertainty in Microbubble Characterization [PDF]
Ultrasound in Medicine & Biology, 2016 There is increasing interest in the use of microbubble contrast agents for quantitative imaging applications such as perfusion and blood pressure measurement. The response of a microbubble to ultrasound excitation is, however, extremely sensitive to its size, the properties of its coating and the characteristics of the sound field and surrounding ...

Effects of intra-arterial microbubbles
, 1960 By means of a partial extracorporeal bypass, incorporating a bubble counting chamber, measured quantities of oxygen and of air microbubbles, having average diameters of 100 and 76 µ, respectively, were introduced into the carotid arteries of dogs.

Applications of Magnetic Microbubbles for Theranostics
Theranostics, 2012 Compared with other diagnostic methods, ultrasound is proven to be a safe, simple, non-invasive and cost-effective imaging technique, but the resolution is not comparable to that of magnetic resonance imaging (MRI). Contrast-enhanced ultrasound employing

Complementary correlation between surface microbubble and droplet shapes
AIP AdvancesPrevious atomic force microscopy studies have suggested that surface micro- and nanobubbles exhibit a flat shape. In this study, we directly observed surface microbubbles formed in an NH3BH3 solution using an optical microscope. No flat microbubbles were
