Abstract
A system for guiding a capsule medical device comprising a magnet from a state in which surface tension of a liquid surface acts on the capsule medical device, the system having: a magnetic guidance device that generates: a reciprocally rotating magnetic field to the magnet at a predetermined frequency around a horizontal axis parallel to the liquid surface; and a guidance magnetic field to the magnet; and a control device that controls the magnetic guidance device to: in a first step, generate the reciprocally rotating magnetic field to the magnet to rotate the capsule medical device to eliminate the effect of the surface tension on the capsule medical device, and in a second step after the first step, generate the guidance magnetic field to the magnet in a direction away from the liquid surface to move the capsule medical device away from the liquid surface.
