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

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.

Cardiovascular imaging and image processing: Theory and practice - 1975; Proceedings of the Conference, Stanford University, Stanford, Calif., July 10-12, 1975

The present collection of papers outlines advances in ultrasonography, scintigraphy, and commercialization of medical technology as applied to cardiovascular diagnosis in research and clinical practice. Particular attention is given to instrumentation, image processing and display. As necessary concomitants to mathematical analysis, recently improved magnetic recording methods using tape or disks and high-speed computers of large capacity are coming into use. Major topics include Doppler ultrasonic techniques, high-speed cineradiography, three-dimensional imaging of the myocardium with isotopes, sector-scanning echocardiography, and commercialization of the echocardioscope. Individual items are announced in this issue.
