The Sonic3D: An Integrated Battlefield Ultrasound with Automated Applications

PocketSonics Inc. proposes to develop an ultra-portable, highly integrated ultrasound device optimized for use by minimally trained users assessing and guiding resuscitation of combat casualties at the initial point-of-care. Current portable systems have limited battery life, cumbersome cables, and oftentimes require two hands or multiple personnel to operate. Furthermore, significant training is required to assimilate the relevant diagnostic information viewed on a distant display. In Phase I of this research, PocketSonics, along with its University of Virginia collaborators, will enhance the current Sonic3D peripheral vascular access device to achieve the Army’s requirements. Software modifications will enable near real-time 3D imaging of central line vessels coupled with automatic needle detection and guidance to assist Army medics with central venous catheterization. Novel computer-aided automation strategies will be implemented to rapidly detect the presence of collapsed lung by analyzing the backscattered acoustic echoes from the parietal pleura. The beamforming, image processing, and automation algorithms examined in this proposal will significantly enhance the detection, diagnosis and triage decision making process of the far-forward battlefield medic and improve patient outcomes. Our Phase I proof of concept analysis will guide future device modifications to enable pre-production prototyping and focused clinical trials in Phase II.
