Capsule endoscopes, conceptual image. Computer artwork of a pill camera travelling inside the intestine. The capsule containing the camera is about 26 millimetres long and can be swallowed by a patient to provide real-time video images of the stomach and intestines. Over a day, the pill moves through the digestive system and the radio antenna continually transmits images, allowing disorders, such as ulcers, to be found.
