Acuson Acuson Corporation was a sonography equipment company specializing in high quality medical ultrasound equipment. Founded in 1979 by Sam Maslak, Rob Younge and Amin Hanafy with the first product (The Acuson 128) shipped in 1983, Acuson pioneered many aspects related to medical ultrasound, most significantly the first fully computerized ultrasound system. In 1996 Acuson introduced the Sequoia 512 and Sequoia C256 systems (the latter for cardiac imaging). The principal architect of the Sequoia was Nelson Wright, who was Acuson's Vice President of Advanced Development. Wright also led the engineering team that developed the Sequoia. The Sequoia quickly became the biggest selling ultrasound system (by dollar volume) and it was manufactured in various versions until December 2008.
