A series of user-centered design methods were applied during the development of an ultrasound system. The methods included hospital site visits, interviews with sonographers, videotapes of examinations and usability testing with simulations of the console and displays. Based on user feedback and preferences, over one-hundred design changes were made to both the console and control panel. The resulting system accommodates users through an adjustable control panel and display monitor. In addition, the control panel and corresponding operator interface software reflects frequency-of-use and sequencing-of-use of functions, leading to more efficient interaction with the system.
