Patent ID: 8010183

Claim:
A detecting system of the position and the posture of a capsule medical device, comprising a posture detecting system for detecting the posture of a main body of the capsule medical device: the posture detecting system comprising: a coil in the capsule provided to the main body of the capsule medical device; a magnetic field generating device for generating an alternating magnetic field for causing the coil in the capsule to generate an induced electromotive force; a magnetic field detecting device for detecting the strength of a magnetic field from the coil in the capsule; a calculation processing unit for calculating the direction and the position of the coil in the capsule in response to a detection value from the magnetic field detecting device; and a control device for calculating an angle formed by the direction of the coil in the capsule calculated by the calculation processing unit and the direction of the alternating magnetic field generated by the magnetic field generating device, and controlling the magnetic field generating device such that the calculated angle is not greater than a set value.
