J Acoust Soc Am
. 2013 Aug;
134(3):1875-85.
PMID: 23967921
Oscillating microbubbles within microvessels could induce stresses that lead to bioeffects or vascular damage. Previous work has attributed vascular damage to the vessel expansion or bubble jet. However, ultra-high speed...

High-frequency subharmonic pulsed-wave Doppler and color flow imaging of microbubble contrast agents
Needles A, Goertz D, Karshafian R, Cherin E, Brown A, Burns P, et al.
Ultrasound Med Biol
. 2008 Mar;
34(7):1139-51.
PMID: 18328617
A recent study has shown the feasibility of subharmonic (SH) flow imaging at a transmit frequency of 20 MHz. This paper builds on these results by examining the performance of...

Phys Med Biol
. 2008 Feb;
53(5):1209-23.
PMID: 18296758
Ultrasound microbubble contrast agents have been demonstrated to scatter subharmonic energy at one-half the driving frequency. At ultrasound frequencies in the 20-40 MHz range, the subharmonic offers the potential to...

IEEE Trans Ultrason Ferroelectr Freq Control
. 2008 Feb;
46(2):372-82.
PMID: 18238434
A novel technique for the selective detection of ultrasound contrast agents, called pulse inversion Doppler, has been developed. In this technique, a conventional Doppler or color Doppler pulse sequence is...

IEEE Trans Ultrason Ferroelectr Freq Control
. 2002 Jan;
48(6):1483-94.
PMID: 11800109
The acoustic properties of ultrasound contrast agents vary widely with agent composition and insonation conditions. For contrast imaging, methods are required to match RF and Doppler processing to each combination...

Semin Liver Dis
. 2001 Jul;
21(2):147-59.
PMID: 11436569
Liver mass evaluation includes two essential elements--lesion detection and lesion characterization. Both of these are greatly improved on sonography with the addition of contrast agents and the use of specialized...
