  • Publication number: 20110319717
    Abstract: An optical system for preventing shaded areas and method of manufacturing the optical system include an imager, at least one illumination source, and an optical window, behind which the imager and the at least one illumination source are positioned. The optical window may include a diffusing element on a portion thereof, for scattering illumination passing through it, such that light scattered from that portion of the window illuminates an otherwise under-illuminated region of impingement of the illumination. The portion on which the diffusing element is located, is positioned outside a field of view of the imager and within a field of illumination of the at least one illumination source.

  • Patent number: 7995798
    Abstract: A device and method for capturing in-vivo images allows for size or distance estimations for objects within the images. According to one embodiment of the present invention there may be provided, in an in-vivo device, at least an imager, an illumination source to provide illumination for the imager, an irradiation source to emit for example a light beam or a laser beam in a body lumen and a processor to calculate, based on image illumination parameter values, an estimate of the size of objects in a body lumen.

  • Publication number: 20110169931
    Abstract: An in-vivo imaging device incorporating a double field of view imaging system, having a wide field of view with moderate magnification, and a narrow field of view with substantially higher magnification, axially superimposed thereon. A single imaging array is used for both fields of view. At least some of the optical elements are shared between both of the two different field of view imaging systems. The imaging elements for the high magnification system, being of substantially smaller diameters than those of the low magnification system, are disposed coaxially with the imaging elements of the low magnification system, and can thus use the same imaging array without the need for deflection mirrors, beam combiners or motion systems. Their location on the axis of the low magnification system means that a small part of the imaging plane, around its central axis, is blocked out by the high magnification components.

  • Publication number: 20110034795
    Abstract: An in-vivo device, system and a method for imaging a body lumen, typically liquid filled body lumen. The in-vivo device may have a specific gravity of about 1 or a volume to weight ratio that enables it to float. The in-vivo device may include an optical system for viewing through a body lumen liquid and another optical system for viewing through a non liquid medium. The in-vivo device may be moved through the body lumen by the liquid movement in that lumen.

  • Publication number: 20100305415
    Abstract: An in-vivo examining device, system and method for identifying the presence of strictures in the small bowel are provided. The in-vivo examining device includes a monitoring mechanism that becomes deactivated when exposed to in-vivo substances native to the small bowel or the colon, and a degradable device body that includes at least a first body portion which degrades at a slow rate when exposed to in-vivo substances native to the small bowel and at a fast rate when exposed to in-vivo substances native to the colon. The degradation of the degradable device body exposes the monitoring mechanism to substances native to the small bowel or the colon and thus indicates whether the examining device has safely passed through the small bowel or whether it is retained in the small bowel due to strictures in the small bowel.
