This study proposed a method for visualizing lymph channels filled with stationary fluid, named contrast-enhanced active Doppler ultrasonography (CEADUS). CEADUS can quantify the translation of ultrasound contrast agent (UCA) due to the acoustic radiation force by Doppler method. In this report, we attempted to visualize a cylindrical channels with a diameter of 0.28 and 0.1-mm filled with a suspension of Sonazoid™ as UCAs in a tissue mimicking phantom containing acoustic scatterers. The single element concave transducer with 14.4-MHz center frequency was scanned at the step of 10 μm in the lateral direction, and ultrasound was emitted with pulse repetition frequency of 2 kHz at each scan line. We obtained two-dimensional images using dynamic information of the UCAs by analyzing for several seconds exposure duration in echo signals at each scanning line. As a result, the CEADUS image could be detected with high sensitivity even when the channel diameter was below the resolution.
