In-field FAST Procedure Support and Automation

描述（由申请人提供）：创伤超声聚焦评估（FAST）程序是一种用于识别腹膜内出血或心包填塞的超声检查。FAST包括在四个特定腹部区域的超声图像中检测自由液体。FAST结果阳性的不稳定患者进行手术，阴性结果稳定的患者倾向于观察。我们建议开发硬件和图像分析算法必要的新手超声操作员执行救生快速程序。该系统将包括一个低成本的超声波探头，连接到坚固耐用的平板电脑上，运行创新的计算机视觉算法，嵌入到一个直观的应用程序中。使用该系统，新手操作员将在视觉引导下从腹部位置获取超声图像，并量化图像中的自由流体。我们最初部署系统的目标是三级和四级创伤

DESCRIPTION (provided by applicant): The Focused Assessment with Sonography for Trauma (FAST) procedure is an ultrasound examination performed to identify intra-peritoneal hemorrhage or pericardial tamponade. FAST involves the detection of free fluid in ultrasound images from four specific abdominal areas. Unstable patients with positive FAST results are operated on, and stable patients with negative results tend to be observed. We propose to develop the hardware and image analysis algorithms necessary for novice ultrasound operators to perform life-saving FAST procedures. The proposed system will consist of a low-cost ultrasound probe, connected to a ruggedize tablet computer, running innovative computer vision algorithms, embedded in an intuitive application. Using that system, a novice operator will be visually guided to acquire ultrasound images from the abdominal locations and quantify the free fluid in those images. The target for our initial deployment of the system is level 3 and 4 trauma centers. These centers must often serve areas spanning hundreds and even thousands of miles; however, they are typically under-staffed and under-equipped. The proposal is being clinically driven by Jeffrey Lowell, MD. He is a USNR Trauma Surgeon, and he was recently deployed to Landstuhl Regional Medical Center, the only Level I Trauma Center outside the U.S.
