So how long till the 18Ds get to play with this thing?

DARPA - Deep Bleeder Acoustic Coagulation

Quote:
The goal of the Deep Bleeder Acoustic Coagulation (DBAC) Program is to develop a portable, lightweight, noninvasive, automated system for the detection, localization, and coagulation of deep bleeders that is operable by minimally trained personnel in the combat environment. The DBAC system will cover the full range of life-threatening bleeders―from the fast bleeder, which causes progressive shock in 30 seconds, to the slow bleeder, which causes progressive shock in 8 hours. Notable progress to date includes―
  • Doppler-based automated bleed detection algorithms. Software is based on unique spectral and power Doppler bleeder signatures that, when coupled to volumetric data, allows for automated bleed detection and localization.
  • Delivery and dosing of high-intensity focused ultrasound (HIFU) has been extensively modeled and tested. Results show that tissue can be raised to within the range of 70 C to 95 C to safely achieve acoustic hemostasis within an operationally relevant timeframe of 30 seconds.
  • Creation of unique materials to enable the testing of the DBAC devices on a full-sized leg mockup. Blood mimicking fluids and tissue mimicking phantoms were developed that were capable of enduring the high temperatures produced by HIFU devices. In addition, minimally perturbing thermal sensors to monitor temperature rise in these phantoms, and new computational techniques, were developed to extend the usefulness of these phantoms.

Cornell Study

Here is a link to a Cornell University study on vein ablation... looks to be very similar. The W/cm2 measurement on this thing is ridiculous and the size would be perfect to carry in the field (well it could always be smaller....)
