Abstract:
A small HIFU system was used to investigate the phase-shift droplet vaporization in vivo and its effect on thermal absorption in tissue-mimicking phantoms. The experiments demonstrated that droplets could be vaporized to bubbles in vivo by the small HIFU system and the volume of bubbles could increase by tens of times. With appropriate droplets concentration, lesion volume produced by HIFU could be increased significantly under the same HIFU parameter.
