(cont’d)
Among other significant features of the Voluson E8 / Voluson E6 ultrasound system are the following:
- Integrated FrontEnd (uses advanced ASIC and FGPA technologies)
- Open connectivity using USB ports
- Bluetooth - wireless connectivity
- high performance 19” LCD monitor
- Low profile, backlit Keyboard
Voluson E8 / Voluson E6 has a digital beam forming system (incorporated in the FrontEnd) which can
handle up to 256 element probes by use of multiplexing.
Signal flow from the Probe Connector Panel, to the FrontEnd (FE) Electronics, to the BackEnd
Processor (BEP), and finally is displayed on the LCD monitor and peripherals.
Voluson E8 / Voluson E6 internal electronics are divided into three:
- Front End (FE) Processor
- Back End Processor (BEP)
- Power Supply Unit
Interconnecting signals from FrontEnd, BackEnd, keyboard, monitor, and power distribution sub-
systems are routed internally.
