Abstract
A method and apparatus for imaging a body lumen are disclosed. According to the method, an imaging apparatus is induced into the body lumen. Structured light from the imaging apparatus is projected into the body lumen. The structured light reflected from anatomical features in the body lumen is detected by the imaging apparatus. A first structured light image is generated from the detected structured light by the imaging apparatus. Non-structured light is emitted from the imaging apparatus into the body lumen. The non-structured light reflected from the anatomical features in the body lumen is detected by the imaging apparatus. A non-structured light image is generated from the detected non-structured light by the imaging apparatus. The frame period of the first structured light image is shorter than the frame period of the non-structured light image. In one embodiment, the imaging apparatus corresponds to a capsule endoscope.
