In capsule endoscopy, a capsule containing a small camera is swallowed by the patient. The capsule then travels to the small intestine and starts taking pictures. The images are then transmitted by radio waves to a receiver. The capsule endoscopy is especially useful for the observation of the small intestine, where other techniques such as colonoscopy are difficult to apply.
In this particular invention provided by Olympus (US Patent No: US 7511733), the front end of the capsule is cut diagonally to provide a large view angle for the camera lens. Spiral projections on the body of the pill help the capsule move forward through the peristaltic motion of the intestine.
