Low-Cost 3D Ultrasound
Ultrasound imaging is a powerful tool for many diagnoses across medicine, but it is currently limited by selectively sampling cross-sectional planes—generally not aligned with anatomical axes—of a three-dimensional (3-D) structure. The 2D image’s dependence on probe positioning and lack of cardinal orientation—transverse, coronal, and sagittal planes, which are standard in computed tomography (CT) and magnetic resonance imaging (MRI)—makes ultrasound nonintuitive and challenging for untrained clinical users.
We are working to overcome these limitations by developing low-cost, fast, and intuitive solutions that enable an unskilled user with a low-end ultrasound system to quickly and consistently acquire diagnostically useful 3-D ultrasound images with accurate anatomical orientation. This promises to not only improve visualization and diagnosis, but also increase workflow and patient throughput, and have point-of-care application in virtually every field of medicine, for every patient population, in both the developed and developing world.
This project has been awarded a Stanford-Coulter Translational Research Grant, and also won the inaugural Point of Care Ultrasound (POCUS) Research Challenge, sponsored by the Emergency Medicine Foundation and GE Healthcare.
