Color technology in video endoscopy.

The psychophysical aspects of the color experience and the clinical significance of color during video endoscopy are introduced in this paper. This introduction includes a description of how colors are rendered in video endoscope systems along with basic colorimetry, the science of color. Together these provide the clinical engineer with an understanding of color and a method of effectively communicating color information. The ability to standardize color rendition in video endoscopy systems is not yet available. Nonetheless, an argument is presented in favor of the clinical engineer normalizing color rendition in video endoscope systems in the hospital and educating the clinicians on managing endoscopic system color performance in the clinical setting.

Insufflation. Complications and recommendations.

This article focuses on complications in colonoscopy related to colonic insufflation. Causes of colonic insufflation complications are examined and methods that may be used to minimize complications are proposed. Testing of state-of-the-art video colonoscope systems is the basis of this analysis of insufflation complications and the resulting recommendations.
