Acoustic Sizing of an Ultrasound Contrast Agent
Ultrasound in Medicine & Biology, 36(10), 1713–1721.
author keywords: Acoustic bubble sizing; Ultrasound contrast agent; Definity (R); Single bubbles; High frequency; Size distribution
MeSH headings : Acoustics; Calibration; Chemical Phenomena; Contrast Media; Fluorocarbons; Microbubbles; Particle Size; Reproducibility of Results; Transducers; Ultrasonics
TL;DR:
This acoustic sizing method has potential for estimating the size distribution of an ultrasound contrast agent noninvasively, and it was observed that similar sized bubbles can give different responses, probably because of shell differences.
