Patent ID: 8241206

Claim:
A system for guiding capsule medical device comprising: a capsule medical device comprising: an imaging unit for imaging an in-vivo image of a subject, and a permanent magnet magnetizing in a known direction relatively fixed with respect to an upward and downward direction of an imaging surface of the imaging unit in a capsule casing, the capsule medical device having a center of gravity at a location deviated from a geometric center of the capsule casing in a direction parallel to a plane parallel to a magnetization direction of the permanent magnet and an imaging direction of the imaging unit and different from the magnetization direction of the permanent magnet, and the capsule medical device maintaining a specific state in which the magnetization direction of the permanent magnet and the imaging direction of the imaging unit are parallel to a vertical plane in liquid introduced into the subject; a magnetic guidance device that applies a magnetic field to the permanent magnet to magnetically guide the capsule medical device in the liquid while maintaining the specific state; and an image display device configured to display on a display screen the in-vivo image by conforming: a direction of an intersection line of the in-vivo image corresponding to an intersection line of: the imaging surface of the imaging unit of the capsule medical device maintaining the specific state, and the vertical plane, to an upward and downward direction of the display screen.
