Human erythrocytes and Optison contrast agent have been exposed to ultrasound, both alone and in combination, in a single-half-wavelength chamber driven at its resonance frequency (fo) of 1.5 MHz. Cell movements were recorded by video microscopy at speeds up to 500 frames/s. The hypothesis that cells near a standing wave pressure node might be stressed by the microbubble products of sonicated contrast agent was examined. In the absence of contrast agent, cells moved rapidly to form an aggregate… CONTINUE READING
