Abstract

The work presented in this paper is to investigate High Intensity Focused Ultrasound (HIFU) technology for acoustic hemostasis to stop internal bleeding in the human limbs, especially those caused by injuries on the battlefield. A ID 64-element cylindrical HIFU array has been used for the feasibility study. Both simulation and experiment results are presented, including acoustic field characterization in a water-tank and HIFU thermal effect (temperature rise) measurement in a tissue-mimicking phantom. This project, Deep Bleeder Acoustic Coagulation (DBAC), is funded by the Defense Advanced Research Program Agency (DARPA).
