SCANNING ENDOSCOPE SYSTEM

摘要

This scanning endoscope system is provided with: a first optical fiber that guides illuminating light supplied by a predetermined light source to an emission end, and emits said light on a target; an optical fiber scanning means that drives the emission end of the optical fiber in a spiral pattern in such a manner that the illuminating light rotationally scans in a spiral pattern from the center to the periphery of an approximately circular scanning region; a light source control means that controls the emission of the illuminating light; an image signal detection means that receives backscattered light returned by the target, and detects an image signal; and an image generation means that uses the detected image signal to generate an image of the target. The light source control means causes the illuminating light to be emitted in pulses when the illuminating light scans the center of the scanning region, and causes the illuminating light to be emitted continuously when the illuminating light scans the periphery of the scanning region.
