Imaging device and related methods
First Claim
1. An imaging device insertable into a human body comprising:
- a sheath;
a light source mounted on a first platform and disposed within the sheath for illuminating at least a portion of a target region;
a photo-sensor mounted on a second platform and disposed within the sheath for sensing light energy received from at least a portion of the target region; and
a movable assembly adapted to move the first platform in at least two dimensions relative to the target region.

Abstract
In one embodiment, the invention provides an imaging device having a light source, a photo-sensor and a scanning assembly. In some embodiments, the light source is fixedly mounted in the first end of an elongated sheath and is adapted for illuminating a target, and the photo-sensor is mounted on the scanning assembly, also in the first end of the elongated sheath, and is adapted to detect light energy from the target. In other embodiments, the light source is movably mounted and the detector is held stationary. In other embodiments, both the light source and the photo-sensor are movably mounted. The scanning devices synchronously capture light energy from each of a plurality locations on the target, the light energy resulting from illumination by the light source, and synchronously digitizes the output from the photo-sensor from each of the plurality of locations on the target to generate an image of the target.
