Dual-frequency acoustic droplet vaporization detection for medical imaging
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control(2015)
摘要
Liquid-filled perfluorocarbon droplets emit a unique acoustic signature when vaporized into gas-filled microbubbles using ultrasound. Here, we conducted a pilot study in a tissue-mimicking flow phantom to explore the spatial aspects of droplet vaporization and investigate the effects of applied pressure and droplet concentration on image contrast and axial and lateral resolution. Control microbubb...
