摘要:
The present invention provides an optical system for illuminating and viewing a target in which an illumination element and a receiving means are disposed behind a single optical window, and which obtains data essentially free of backscatter and stray light. The optical window of the optical system is configured such that it defines a shape having at least one focal curve, i.e., an ellipsoid shaped dome. The illumination element and the receiving means are geometrically positioned on the focal curve plane or in proximity of the focal curve plane, such that, when illuminating, rays from the illumination elements, that are internally reflected from the optical window, will not be incident on the receiving means.

An in-vivo imaging device including a camera may include a frame storage device. Systems and methods which vary the frame capture rate of the camera and/or frame display rate of the display unit of in-vivo camera systems are discussed. The capture rate is varied based on physical measurements related to the motion of the camera. Alternatively, the frame capture rate is varied based on comparative image processing of a plurality of frames. The frame display rate of the system is varied based on comparative image processing of a multiplicity of frames. Both the frame capture and the frame display rates of such systems can be varied concurrently.

An in vivo imaging device may include a capsule shaped housing and an image sensor. The capsule shaped housing may have a longitudinal axis and a window. The image sensor (e.g., a CMOS sensor) may include a pixel array portion and a circuitry portion. The circuitry portion may be segregated, for example longitudinally, from the pixel array portion. The pixel array portion may be disposed within said housing substantially parallel to said longitudinal axis.A light deflecting element disposed at an angle smaller than 45 degrees with respect to the pixel array portion introduces image distortion which is compensated by a distortion compensation mechanism.
摘要:
A device, system and method for capturing in-vivo images allows for size or distance estimations for objects within the images. A scale may be overlayed on or otherwise added to the images and, based on a comparison between the scale and an image of an object, the size of the object and/or the distance of the object from an imaging device may be estimated or calculated.

摘要:
The present invention relates to a method and system for the in vivo determination of the presence and/or concentration of biological and/or chemical substances in body lumens. The system of the invention comprises a solid support, the support being inserted into a body lumen and having immobilized thereon at least one reactant capable of reacting with the substance resulting in an optical change; and a detecting unit, in communication with the support, capable of detecting a reaction resulting in an optical change between the reactant and the substance.
