The CCD built into the Distal End receives reflected light (image data) from the body cavity, and sends the image data to the Video Processor through the video cable. The image data are converted into the image signal by the Video Processor, and the image inside the body cavity is displayed on the Monitor.

# PENTAX Medical Video Processor (EPK-i5010):

The PENTAX Medical EPK-i5010 video processor consists of a video system, integrated light source, monitor, and ancillary equipment. This processor, when connected to a compatible ENT scope is intended for ENT endoscopic diagnosis, treatment and video observation.

The PENTAX Medical EPK-i5010 includes PENTAX i-Scan™, a digital, filter-based postprocessing imaging enhancement technology with three modes, i-Scan 1, 2 and 3. i-Scan 1 enhances image topography and edges and i-Scan 2 and 3 enhance the color tone of the image by dissecting and recombining the individual red, green and blue (RGB) components of a white light image. The EPK-i5010 with i-Scan has been previously cleared for use with bronchoscopes, gastroscopes, colonoscopes, and duodenoscopes,

PENTAX i-Scan™ modes 1, 2, and 3, are intended to give the user an enhanced view of the texture of the mucosal surface and blood vessels. i-Scan 1 provides the user with a view that sharpens surface vessels and enhances surface texture of the mucosa. i-Scan 2 provides the user with increased visibility of blood vessels while also providing the same enhancements to the mucosa achieved in i-Scan 3 provides the user with increased visibility of blood vessels including dimly illuminated far-field regions while also providing the same enhancement to the mucosa achieved in i-Scan 1. The user can select either white light image or i-Scan modes by pressing a pre-programmed button on the scope, by using a pre-programmed foot pedal or by pressing a keyboard button. i-Scan is intended to be used as an optional adjunct following traditional white light endoscopy and is not intended to replace histopathological sampling.
