In-vivo imaging device with backscatter blocking

摘要

The invention provides a device for in-vivo imaging, for example, using an in-vivo imaging device including an imager a lens and an illumination source, all positioned behind a single viewing window. The in-vivo imaging device may include an element to block light from reaching a point of reflection on the inner surface of the viewing window, thereby preventing the light from being received by the imager.

主权项

1. An in vivo imaging device having a central longitudinal axis, the in vivo imaging device comprising:
a dome shaped viewing window; an illumination source; an imager; and at least one barrier positioned to block light from the illumination source from reaching at least one specific spot on the dome shaped viewing window, the at least one barrier placed at a position along a radius of a section of the device perpendicular to the central longitudinal axis of the device that is between the illumination source and said dome shaped viewing window, wherein the imager, the at least one illumination source and the at least one barrier are situated on the concave side of the dome shaped viewing window.
