The GE Voluson E10 is the top-of-the-line premium 4D OB/GYN ultrasound machine. The E10 supersedes but does not replace the lower priced Voluson E8. The E10 offers 4 times the processing power of the E8 a larger screen, sophisticated beam formation and new rendering technologies. The new processing power speeds render times and smooths frame rates so that HD live is even more realistic. However the steep price difference with the E8 means that for now most doctors will still choose the proven Voluson E8.
