Ultrasound Imaging using the Low-Frequency Response of Microbubbles
When microbubbles are excited by two frequency signals, a nonlinear response signal may occur at the difference frequency. As these two frequencies are made close, this nonlinear response will reside at lowfrequency region. We have derived a theory for the weak short-pulse response based on a two-frequency approximation, which provides the pressure and the bandwidth dependence properties of the...
متن کاملIntracranial clot lysis with intravenous microbubbles and transcranial ultrasound in swine.
BACKGROUND AND PURPOSE Destruction of microbubbles by transcutaneous low-frequency ultrasound (LFUS) has been used to lyse adjacent clot and recanalize acutely thrombosed vessels. LFUS with intraarterial microbubbles has been shown to lyse cerebral clot rapidly in pigs without thrombolytic drugs. We hypothesized that intravenous platelet-targeted microbubbles with LFUS may be a rapid noninvasiv...

15 صفحه اولLow-frequency low energy ultrasound combined with microbubbles induces distinct apoptosis of A7r5 cells.
The present study aimed to investigate whether low frequency low energy ultrasound combined with microbubbles induces apoptotic cell death of A7r5 rat aortic vascular smooth muscle cells, and to identify the possible mechanisms underlying this effect. Ultrasonic waves (45 kHz with 0.3 Wcm2 of intensity for 0, 10, 20 and 30 sec) were used together with different dosages of SonoVue™ microbubbles ...
