Dear Colleagues, Helping a colleague in Electrical and Computer Engineering here at UMN to promote a talk tomorrow on the underlying computing technology of CT, in which the speaker Prof. Barry Gilbert will present that CT is at least in part a Mayo/Minnesota story... The time of 4pm is Central Time and Zoom link and title, speaker, and abstract are below. Thanks. Best, Jeff Date: April 20, 2023 Time: 4pm Location: Zoom, https://umn.zoom.us/j/94220596055 Host: Prof. Marc Riedel Speaker: Prof. Barry Gilbert Title: The Origin And Evolution of X-Ray Computed Tomography at Mayo Clinic, 1960-1980 Abstract: The advent of X-ray computed tomography (X-ray CT) in the 1970s is commonly attributed to a now-defunct British company. In fact, the earliest work on X-ray CT began at Mayo Clinic in the early 1960s with a long series of engineering developments carried out by a staff of 50 individuals, which continued until the late 1970s. A significant number of technical “firsts” occurred during those years, virtually all of which appear in modern rotating-gantry machines. This two-decade history, with a review of some of these breakthroughs, will be described in this seminar, by one of the engineers (BKG) who contributed to the successful development of the prototype first-article demonstrator. Bio: Barry Gilbert is a Professor of Biomedical Engineering and Director of the Special-Purpose Processor Development Group at Mayo Clinic in Rochester MN, an AIMBE Fellow and an IEEE Life Fellow. He received a B.S. degree in electrical engineering from Purdue and a Ph.D. in biomedical engineering from U. Minnesota and Mayo Clinic. Since 1970 his research interests have been in the design of hardware for specialized supercomputers. His team has designed more than 450 integrated circuits, and has contributed to the development of more than two dozen special purpose computers, from chip-sized processors to cabinet-size supercomputers. *Please connect at:* *Mastodon <https://mastodon.social/@JustCodeCulture> Twitter <https://twitter.com/justcodeculture> ** Linkedin <https://www.linkedin.com/in/jeffrey-yost-b714566>* *Jeffrey Yost, Ph.D. * Director, Charles Babbage Institute <http://www.cse.umn.edu/cbi>; Research Professor, History Sci/Tech/Med 222 21st Avenue South, University of Minnesota; Minneapolis, MN 55455 *Studies in Computing and Culture book series, Johns Hopkins U.
