Device and system for in vivo imaging
The present invention provides a system and method for obtaining in vivo images. The system contains an imaging system and a transmitter for transmitting signals from a camera to a receiving system located outside a patient.
1. A swallowable capsule for imaging the gastrointestinal tract, the capsule comprising:
an elongated housing, having a longitudinal axis, comprising a single uninterrupted transparent dome shaped window having an apex located at an end of the longitudinal axis;
an optical system located behind the single uninterrupted transparent dome shaped window and having an optical path along the longitudinal axis;
an imager located behind the single uninterrupted transparent dome shaped window and imaging the gastrointestinal tract via the single uninterrupted transparent dome shaped window and via the optical system; and
an illumination element configured to provide illumination in a ring around the imager and illuminating the gastrointestinal tract via the single uninterrupted transparent dome shaped window.
2. The capsule of claim 1 wherein the optical system and illumination element are on substantially the same plane, and the imager is located at a point behind the optical system relative to the dome.
3. The capsule of claim 2 wherein the optical system comprises a lens.
4. The capsule of claim 1 wherein the optical system is arranged to focus an image on the imager.
5. The capsule of claim 1 wherein the illumination element includes a plurality of LEDs.
6. A swallowable capsule for imaging the gastrointestinal tract, the capsule comprising:
an elongated housing, having a longitudinal axis, comprising a single uninterrupted transparent dome shaped window having an apex located at an end of the longitudinal axis;
an optical system located behind the single uninterrupted transparent dome shaped window and having an optical path along the longitudinal axis;
an imager located behind the single uninterrupted transparent dome shaped window and imaging the gastrointestinal tract via the single uninterrupted transparent dome shaped window and via the optical system; and
a plurality of illumination sources arranged in a ring around the imager and illuminating the gastrointestinal tract via the single uninterrupted transparent dome shaped window.
7. The capsule of claim 6 wherein the optical system and illumination sources are on substantially the same plane, and the imager is located at a point behind the optical system relative to the dome.
8. The capsule of claim 6 wherein the illumination sources include LEDs.
