Acuson Confidential Sequoia Ultrasound Technology

SEQUOIA ULTRASOUND TECHNOLOGY

The Sequoia system is the most fundamental and far-reaching
advance in ultrasound imaging technology since the advent of
Computed Sonography in 1983. It incorporates four foundation
technologies that produce dramatic image quality, performance,
and functionality improvements in all modes of operation. These
foundation technologies include:

• Sequoia proprietary Coherent Image Formation tech nology

• Doppler Technology

• DIMAQ™ Integrated Ultrasound Workstation

• Transducer Technology

DISPLAY TECHNOLOGY

A great deal of foresight and research resulted in the industrial
design of the Sequoia ultrasound system. The Sequoia system’s
design is based on human factors analysis which involved extensive
research in a combination of ergonomics and user interface design.

The tilt-and-swivel display, height-adjustable keyboard and display ,
portability, micro-positioning, quieter system operation, simplif ied
maintenance, tactile controls, and operator-focused speaker system
are just a few examples of an industrial design that offers fatigue­free operation and timeless style.

Partnerships with two other leading electronics companies have
produced some of the highest density ASICs (Applicati on Specific
Integrated Circuits) and 16-layer printed circuit boards.

A partnership with a major European manufacturer has resulted in
the availability of display monitors of high-information density.
