  • Publication number: 20190090778
    Abstract: A capsule endoscope position detection method includes first to third steps. The method uses at least four antennas configured to receive signals wirelessly transmitted from a capsule endoscope inside a subject. In the first step, a calculation device calculates a distance difference between a first distance and a second distance on the basis of the signals received by two of the at least four antennas. The first distance is a distance between one of the two antennas and a capsule endoscope. The second distance is a distance between the other of the two antennas and the capsule endoscope. In the second step, the calculation device selects at least three distance differences among the distance differences calculated in the first step. In the third step, the calculation device calculates a Z coordinate of the capsule endoscope on the basis of the selected distance difference.
