Abstract
A system for estimating the position of an imaging capsule that examines the gastrointestinal tract of a user, including an imaging capsule for examining inside the user; and a recorder for communicating with the imaging capsule from outside the user. The imaging capsule includes a controller for controlling functionality of the imaging capsule, a transceiver for communication with the recorder and a coil for transmission of electromagnetic signals. The recorder includes a controller for controlling functionality of the recorder, a transceiver for communication with the imaging capsule and a coil for receiving electromagnetic signals from the coil of the imaging capsule. Wherein the recorder determines the location of the imaging capsule based on measurements of the amplitude of the electromagnetic signals transmitted by the coil in the imaging capsule.
