Introduction
Introduction
The Smithsonian Videohistory Program, funded by the Alfred P. Sloan Foundation from 1986 until 1992, used video in historical research. Additional collections have been added since the grant project ended. Videohistory uses the video camera or digital recorder as a historical research tool to record moving visual information. Video works best in historical research when recording people at work in environments, explaining artifacts, demonstrating process, or in group discussion. The experimental program recorded projects that reflected the Institution's concern with the conduct of contemporary science and technology.
Smithsonian historians participated in the program to document visual aspects of their on-going historical research. Projects covered topics in the physical and biological sciences as well as in technological design and manufacture. To capture site, process, and interaction most effectively, projects were videotape recorded in offices, factories, quarries, laboratories, observatories, and museums. Resulting footage was duplicated, transcribed, and deposited in the Smithsonian Institution Archives for scholarship, education, and exhibition. The collection is open to qualified researchers.

Ramunas Kondratas, curator at the National Museum of American History, documented the history, development, commercialization and applications of diagnostic ultrasound. Session One was recorded between January 20 through January 24, 1997 at Acuson Corporation located at Mountain View, California. Interviewees included scientists, engineers, managers, and a patent attorney from Acuson. The session took place at several sites on the Acuson campus. Interviews focused on the history of the company, the development of ultrasound and transducer technologies, design and commercial development of the equipment, the manufacturing process, clinical applications, education of clinicians, and the patenting process.
Kondratas also interviewed several of the participants on audiotape. The tapes and transcripts complement the videotape sessions and are also available through the Institutional History Division, Smithsonian Institution Archives.
This collection consists of one interview session, totaling approximately 12:00 hours of recording and 203 pages of transcript. There are three generations of tape for each session: originals, dubbing masters, and reference copies. In total, this collection is comprised of 24 original Betacam videotapes, 12 dubbing master U-matic videotapes, and 6 reference copy VHS videotapes. The collection has been remastered digitally, with 24 motion jpeg 2000 and 24 mpeg digital files for preservation, and 24 Windows Media Video and 24 Real Media Video digital files for reference.

Medical diagnostic ultrasound systems use high-frequency sound waves to produce images of soft tissues and internal body organs. First introduced to the medical world in the 1950s, it is a widely used diagnostic imaging modality today. Ultrasound exams are non-invasive and generally considered safe at the power levels used for diagnostic exams. Ultrasound is used in obstetrical, abdominal, urological, vascular and cardiac applications.
Sonar - the technique of sending sound waves through water and observing the returning echoes to characterize submerged objects - inspired early ultrasound investigators to explore ways to apply the concept to medical diagnosis. Early on, ultrasound was used to detect gallstones, breast masses, and tumors. During the early 1970s, the technology advanced to gray scale ultrasound systems that produce static images of internal organs easily recognizable to physicians. Later in the 1970s, the development of real-time ultrasound imaging enabled physicians to see continuous live-action images of the area under investigation. The 1980s saw the introduction of spectral Doppler and later color Doppler which depicts blood flow in various colors to indicate speed of flow and direction.
In 1979, Samuel H. Maslak, Sc.D., began developing a new approach to medical ultrasound imaging. The scanners used in the existing ultrasound technology produced satisfactory diagnostic images from the returning echoes through sixty-four electrical channels, but the machines could not refine the images because computers for ultrasound imaging did not exist. Dr. Maslak's work in applying computer technology to ultrasound led to the founding, with Robert Younge and Amin Hanafy, of Acuson Corporation in 1982. Acuson introduced its first product in 1983, the Acuson 128 Computed Sonography System which applied computer technology to diagnostic ultrasound. The 128 channel software-controlled image formation process provided black-and-white and color ultrasound images with high resolution and clarity.
Acuson continued to develop ultrasound technology. The introduction of the Sequoia 512 system in 1996 provided clinicians with twice the amount of image information in half of the time. Acuson's development of a new way to form ultrasound images called Coherent Image Formation used both the phase and the amplitude information from ultrasound echoes to produce images. Conventional ultrasound systems produced images based only on the amplitude information. This discovery offered the user increased spatial and temporal image resolution.
Bradford C. Anker was educated at Purdue University receiving the B.S. degree in industrial engineering in 1968. Anker joined the Hewlett-Packard Automatic Measurement Systems Division in 1968. During his six years there, Anker progressed through the materials management function and was master scheduling manager when he left Hewlett-Packard to join Spectra-Physics, where he held several senior manufacturing and management positions during his ten years at the company. Anker was Vice President, manufacturing, for Margaux Controls before joining Acuson in 1983, as Vice President, manufacturing.
Corinne Augustine was educated at the University of Florida where she received the B.S.I.E. degree in 1980, and the M.B.A. degree in 1991 at Stanford University. Augustine joined Frito Lay Company in 1980 as the Industrial Engineering Department Manager. She then joined Intel Corporation in 1984 as the Industrial Engineering and Production Manager. From 1986 through 1989, Augustine was the New Products Project Manager at Sun Microsystems.
