Disclosed herein are systems, methods, and structures providing accurate and easy to use size measurement of physiological features identified from endoscopic examination. In sharp contrast to the prior art, systems, methods, and structures according to the present disclosure employ structured light that advantageously enables size and/or distance information about lesions and/or other physiological features in a gastrointestinal (GI) tract. Advantageously, systems, methods, and structures according to the present disclosure are applicable to both capsule endoscopes and insertion endoscopes.

Endoscope employing structured light providing physiological feature size measurement

An endoscopy capsule having an image collecting capacity includes a deformable member configured to inflate when exposed to body liquid. The deformable member includes an effervescent material. When the effervescent reacts with water the resulting Carbon-Dioxide gas reduces the specific gravity of the endoscopy capsule. The capsule is contained within a shell or dome when swallowed. The shell or dome is configured dissolve in either a low or high pH environment.

Capsule device having variable specific gravity

A method and apparatus of aligning a lens module with respect to an image sensor device for a capsule camera are disclosed. The image sensor device comprises multiple pixel arrays and the lens module comprises multiple lens sets to form multiple images corresponding to multiple fields of view associated with the multiple lens sets, and each lens set forms one image for one corresponding pixel array associated with one field of view. A method according to the present invention present invention, one or more test images are presented in the multiple fields of view associated with the lens module. Multiple images in the multiple fields of view are captured using the multiple pixel arrays. Metric measurement is derived based on the multiple images captured by the multiple pixel arrays. Lens alignment between the lens module and the image sensor device is then adjusted based on the metric measurement.
