Abstract
Ultrasound contrast agents are often used to measure flow rate in the microvasculature; however, the oscillation of these agents in capillary-sized tubes has not been directly observed. Here, oscillations of microbubbles are examined in microvessel phantoms with diameters similar to those of capillaries. High-speed camera images demonstrate the effects of ultrasonic pressure and tube diameter and length on microbubble expansion and fragmentation occurrence. Microbubble displacement due to radiation force is also demonstrated in a phantom microvessel.
