    Abstract: Apparatuses and methods for scanned beam endoscopes, endoscope tips, and scanned beam imagers are disclosed. In one aspect, a scanned beam endoscope includes at least one light detection element that collects light reflected from a FOV through one or more openings in the scanner of the endoscope. In another aspect, the illumination optical fiber may be positioned so that its output end is laterally positioned in relation to the scanner. In yet another aspect, the scanner is oriented to provide a non-axial FOV.

    Abstract: An endoscope system and method includes an endoscope tip coupled to a endoscope console for providing images of anatomical features imaged using the endoscope system. The system also includes a calibration device having known optical properties. The calibration device is imaged using the endoscope system, and data corresponding to the image is obtained. This data are compared to data corresponding to the known optical properties of the calibration device. Based on this comparison, calibration data corresponding to imaging errors of the endoscope system are obtained. The calibration data are used to calibrate the endoscope system.

    Abstract: A scanning endoscope, amenable to both rigid and flexible forms, scans a beam of light across a field-of-view, collects light scattered from the scanned beam, detects the scattered light, and produces an image. The endoscope may comprise one or more bodies housing a controller, light sources, and detectors; and a separable tip housing the scanning mechanism. The light sources may include laser emitters that combine their outputs into a polychromatic beam. Light may be emitted in ultraviolet or infrared wavelengths to produce a hyperspectral image. The detectors may be housed distally or at a proximal location with gathered light being transmitted thereto via optical fibers. A plurality of scanning elements may be combined to produce a stereoscopic image or other imaging modalities. The endoscope may include a lubricant delivery system to ease passage through body cavities and reduce trauma to the patient. The imaging components are especially compact, being comprised in some embodiments of a MEMS scanner and optical fibers, lending themselves to interstitial placement between other tip features such as working channels, irrigation ports, etc.
