Ultrasounds are a critical part of modern health care, helping to image soft tissue and organs, measure blood flow, and monitor fetal development. But the technique has constraints, including a limited field of view and the potential for operator error. To address current shortfalls and push the technology toward new applications, Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and a team of Caltech researchers have developed a system that can perform ultrasound tomography (UST) imaging on whole cross-sections of the body.
