Abstract
A system, apparatus and method may indicate in-vivo device location within a body utilizing for example illumination irregularities for calculation of location. There may be provided with an in-vivo imaging device a set of dedicated illumination source and a set of detectors located on an in-vivo device, such as a swallowable capsule.
Claims12
An in-vivo system comprising:
- an autonomous in vivo device, the device comprising:
- a primary light source, to illuminate a body lumen for imaging, positioned behind an optical window;
- an imager, positioned behind the optical window;
- a dedicated light source, not positioned behind the optical window, to illuminate the body lumen;
- and
- a processor to, based on signals from the imager generated based on reflection of light emitted by the dedicated light source, determine an indication of movement from a first lumen having a first diameter to a second lumen having a second diameter based on the imager detecting less light in the lumen where the lumen walls are closer to the outer shell.

A method for operating an in-vivo system, the method comprising:
- in an autonomous in vivo device:
- via a primary light source positioned behind an optical window,
- illuminating a body lumen for imaging;
- capturing images via an imager positioned behind the optical window;
- illuminating the body lumen for locating the in vivo device using a dedicated light source, not positioned behind the optical window;
- and
- collecting reflected light using a detector;
- and
- indicating a movement from a first lumen having a first diameter to a second lumen having a second diameter based on the detector detecting less light in the lumen where the lumen walls are closer to the outer shell.
