Abstract

Imaging endoscopes constitute a key device in medical praxis. The ability to access internal cavities through any tubular duct of the human body makes endoscopy a powerful tool for performing diagnostics, treatments and surgical procedures in a minimally invasive way [1]. Optical fibers have enabled the implementation of flexible devices, enhancing the guidance capacity and reducing patient's discomfort. The core of fiber endoscopes is a coherent fiber bundle that transmits the image from the distal to the proximal end maintaining the spatial characteristics of the image [2]. In this work, we analyze the impact of crosstalk in the contrast of the image as a mean of evaluating the quality of the endoscope in terms of a useful parameter from the clinical point of view.
