Is the system capable of easily interfacing with hard-copy devices videotape recorders and computerized image management systems Summary During the 1990s the video-image colonoscope supplanted the fiberoptic colonoscope as the preferred instrument for colonoscopy. The availability of two distinct technologies for generating color images colorchip vs. RGB sequential provides the endoscopist with a choice of basic systems each with its own advantages and disadvantages. Although the basic shape and function of the instrument have remained unchanged recent advancements including the development of smaller-diameter insertion tubes instruments with adjustable stiffness improvements in image resolution and advanced video processor features have continued the evolution of the colonoscope.
