 DESCRIPTION (provided by applicant): Ultrasound has found wide clinical diagnostic acceptance, with portable systems already in use for triage in urgent care. We propose to radically improve access to high-quality imaging for detection of Abdominal Aortic Aneurysms, Trauma (FAST exam) and Pulmonary Edema through two point-of-care developments: Device A: a hand-held phased-array system which connects via USB to a commodity tablet for its display and power. Device B: a telemedicine phased-array which can be operated by an untrained user, and generates volume data for remote interpretation. Device A has a low enough cost to be broadly deployed to urgent-care physicians and paramedics with basic ultrasound skills. Device B is entirely operator- independent and can be used by untrained individuals in rural, aviation, disaster-relief and military settings. A remote physician viewing te volume data Device B acquires will make the diagnosis. To deliver these medical benefits we plan to bring together innovations in: Transducers, to substantially decrease system power consumption. We propose using a recently developed micromechanical (MEMS) device to achieve this. Image reconstruction. Our mathematical approach differs from the beam formation in use in standard ultrasound systems and enables compact, low-cost electronics while maintaining high image quality. System design, to achieve a product cost which will significantly broaden access to ultrasound imaging in the three target applications. In Phase I, Device A's design will be risk-reduced and specified. The goal of Phase II is to produce and clinically evaluate a prototype. The technology developed in Phases I and II will be directly applied to commercialization of Device A and Device B.

 描述（由适用提供）：超声已经发现了广泛的临床诊断接受性，并且已经使用便携式系统用于Triage。我们建议通过两种护理开发项目从腹部主动脉瘤，创伤（快速检查）和肺水肿检测高质量成像的访问途径：设备A：手持式拨号阵列系统，该系统通过USB连接到CORSSTITY PARTITITY的显示和功率。设备B：可以由未经培训的用户操作的远程医疗阶梯式阵列，并生成用于远程解释的音量数据。设备A的成本足够低，可以将其广泛部署到具有基本超声技能的紧急护理医生和护理人员。设备B完全独立，可以在粗糙，航空，灾难性和军事环境中使用未经训练的人使用。远程物理查看卷数据设备B获取将使诊断。为了提供这些医疗福利，我们计划将创新汇总到：传感器中，以大大降低系统功耗。我们建议使用最近开发的微机械（MEMS）设备来实现这一目标。图像重建。我们的数学方法与标准超声系统中使用的光束形成不同，并在保持高图像质量的同时，可以实现紧凑的低成本电子设备。系统设计，以实现产品成本，该成本将大大扩展三个目标应用程序中对超声成像的访问。在第一阶段，设备A的设计将被降低和指定。 II期的目标是生产和临床评估原型。在第I和II阶段开发的技术将直接应用于设备A和设备B的商业化。
