Patent ID: 8469879

Claim:
A capsule guiding system comprising: a capsule medical device including in a capsule casing an imaging device configured to take an in-vivo image of a subject and a magnet with a magnetization direction that is relatively fixed with respect to the imaging device; a magnetic guiding device configured to apply a magnetic field to the magnet of the capsule medical device introduced into the subject and to guide the capsule medical device with the magnetic field; a display unit configured to display the in-vivo image of the subject taken by the imaging device; and a control unit configured to cause the magnetic guiding device to apply a magnetic field in a reference direction to the magnet, configured to initialize a rotation angle of an image taken by the imaging device when the magnetization direction of the magnet is oriented to the reference direction following the magnetic field in the reference direction, configured to perform, referring to the image, rotation correction on subsequent in-vivo images, and configured to cause the display unit to sequentially display the in-vivo images on which the rotation correction is performed, wherein the control unit is configured to determine whether performing initialization of the rotation angle is necessary, and upon determination that performing the initialization is necessary, the control unit causes the magnetic guiding device to apply the magnetic field in the reference direction to the magnet and initializes the rotation angle of the image taken by the imaging device when the magnetization direction of the magnet is oriented to the reference direction following the magnetic field in the reference direction.
