A detailed understanding of the response of single microbubbles subjected to ultrasound is fundamental to a full understanding of the contrast-enhancing abilities of microbubbles in medical ultrasound imaging, in targeted molecular imaging with ultra

Individual ultrasound contrast agent microbubbles (BR14) were characterized acoustically. The bubbles were excited at a frequency of 2 MHz and at peak-negative pressure amplitudes of 60 and 100 kPa. By measuring the transmit and receive transfer func

Transfer functions of US transducers for harmonic imaging and bubble responses

Autor: J. Borsboom, Nico de Jong, Guillaume Matte, Jeroen Sijl, Paul L. M. J. van Neer

Publikováno v: Ultrasonics, 46(4), 336-340. Elsevier

Current medical diagnostic echo systems are mostly using harmonic imaging. This means that a fundamental frequency (e.g., 2 MHz) is transmitted and the reflected and scattered higher harmonics (e.g., 4 and 6 MHz), produced by nonlinear propagation, a

Oscillating phospholipid-coated ultrasound contrast agent microbubbles display a so-called " compression-only" behavior, where it is observed that the bubbles compress efficiently while their expansion is suppressed. Here, a theoretical understanding

The influence of the stabilizing phospholipid-coating on the nonlinear dynamics of ultrasound contrast agent microbubbles is investigated. We record the radial dynamics of individual microbubbles with an ultra high-speed camera as a function of both

Coated microbubbles, unlike tissue are able to scatter sound subharmonically. Therefore, the subharmonic behavior of coated microbubbles can be used to enhance the contrast in ultrasound contrast imaging. Theoretically, a threshold amplitude of the d

Ultrafast framing optical and acoustical recording of nonlinearly oscillating microbubbles

Publikováno v: 2009 IEEE International Ultrasonics Symposium.

Microbubble nonlinear behavior improves detection efficacy of ultrasound contrast agents (UCAs), but not all microbubble sizes present in the dispersed UCA population will contribute to the detection signal. This paper experimentally studies the rela
