The existing design of ultrasound real-time scanners is not satisfactory from the standpoint of operator comfort or efficient use. As currently configured, these units are cumbersome and fatiguing to use and require unnecessarily complex and time-consuming movements on the part of the operator. Redesigning ultrasound scanners so that they conform to accepted principles of ergonomics or human-factor engineering should make it possible to achieve increased efficiency and improved study quality.
