摘要： A system and method for guiding a capsule medical device. The method includes: changing, by a control unit, a gradient distribution of a gradient magnetic field generated by a magnetic field generator in a vertical direction, the magnetic field generator generating at least the gradient magnetic field in the vertical direction to guide a capsule medical device that includes a magnetic-field responding unit; detecting, by a position detector, a position of the capsule medical device in the vertical direction based on a gradient distribution of the gradient magnetic field generated by the magnetic field generator, a physical parameter of the capsule medical device, and a physical parameter of a liquid when the capsule medical device starts to move; and setting, by the control unit, the magnetic field generated by the magnetic field generator based on the detected position of the capsule medical device in the vertical direction.

摘要： A capsule medical device guidance system includes a capsule medical device with a response unit; a generating unit that generates a magnetic field to the response unit, an input unit that inputs operation information to magnetically guide the medical device, a control unit that controls the generating unit to guide the medical device according to the operation information, and a selection unit that selects a contact mode or away mode, for bringing the medical device into contact with a boundary surface in liquid in a subject in the contact mode, the medical device being moved away from the boundary surface in the away mode. The control unit generates the magnetic field in which a total force is oriented toward the boundary surface side, and the control unit controls the generating unit such that the total force is oriented toward a direction other than the direction for the away mode.
