Abstract
A system is for detecting a position of a device. The device is swallowed, passes through a subject, and includes a magnetic field generator generating a constant magnetic field. The system also includes a position transducer. The position transducer includes a magnetic detector detecting an intensity of a magnetic field component parallel to a constant magnetic field output from the magnetic field generator, and a position processor calculating a position of the device in the subject based on the intensity detected by the magnetic detector.
