Abstract
An encapsulated medical device guidance system, and a method of controlling the system, in which a magnetic generator acts on a magnet built into a capsulated medical device, and generates a magnetic field for controlling the position and/or posture of the capsulated medical device, and a control unit has a dynamic torque estimation unit to estimate a dynamic torque to be applied to the encapsulated medical device in a target posture, controls a magnetic field generated from the magnetic field generator so that a magnetic torque generated by the magnetic field generator becomes proportional to a dynamic torque estimated by the dynamic torque estimation unit, and controls the posture of a capsule endoscope by considering gravity applied to the capsule endoscope itself.
