The used GE Vivid e90 is one of three GE cardiovascular ultrasound machines to introduce GE’s innovative cSound beamforming technology. The e90 is a premium cardiac ultrasound machine, remaining among the top choices in high-end cardiovascular ultrasound machines
cSound technology on the refurbished Vivid e90 was released in 2015 as a completely new beamforming technology, not used by any other manufacturer. cSound uses software instead of hardware to perform beamforming functions, which acquires a complete scan of the heart before displaying it on its 22″ OLED screen. GE claims it uses 10-15% more data than traditional hardware beamforming.
