The 4400 is a fully digital electronic endoscope system capable of vividly depicting the future of endoscopic diagnosis. Advanced processing technology allows the 4400 to retain image fineness and precision picture quality when viewing the most obscure changes in living tissue, or very subtle changes in mucosal detail. The result is a dramatic improvement in quality diagnosis that can be documented and digitally stored on a network, or on a Compact Flash media card inserted into the processor unit.
