The Stanford-Ames portable echocardioscope: A case study in technology transfer

Abstract

A battery powered echocardioscope is described which was clinically validated on both normal subjects and patients. Its single hand held transducer provides a one dimensional image of the moving cardiac anatomy in real time. Its major advantages over existing ultrasonoscopes are its simplicity, portability, dc operation, and potentially lower production costs. Its versatility and diagnostic value were demonstrated by experienced echocardiographers.
