The primary focus of this innovation is the expansion of health care capabilities, developed by NASA, for use on Earth to increase diagnostic capabilities in under-served populations. The innovation involves rapid training and remote expert guidance of non-expert users in dispersed centers to perform targeted ultrasound examinations using in-expensive, portable ultrasound devices which are coupled to centers of excellence through the internet, cell, or telephone networks. The target populations of this innovation are remote, rural, or underserved populations where immediate and accurate diagnostic information concerning numerous health conditions including obstetrics, child care, musculoskeletal disease, trauma, kidney, liver, gallbladder disease, and cardiovascular health could be assessed. Currently, there is a long waiting period for a patient to obtain a radiologic test such as a CT, MRI, or ultrasound scan which are extremely expensive and site limited. The portable ultrasound devices are 1/6th the cost of previous devices, and can be placed in non-hospital, community settings, staffed by remote physicians for a fraction of the cost of a similar examination under standard conditions. Recent NASA investigations have demonstrated that ultrasound can provide similar diagnostic images to these expensive interventions and that the ultrasound examinations can be performed by non-physicians with high accuracy: this proposal will modify these techniques used successfully on the International Space Station and Winter Olympic Games to expanded health care on the Earth.
