Encapsulated medical device guidance system, and a method of controlling the same

An encapsulated medical device guidance system comprising:

• an encapsulated medical device having an internal biological information acquisition unit to acquire internal biological information, a communication unit to output the acquired internal biological information to the outside as an output signal, and a magnet;
• a plurality of receiving antennas which are different from one another in a direction in which receiver sensitivity in a directionality thereof is highest and receive the output signal;
• a selector which is connected to the plurality of antennas and selects a path for the signal;
• a receiving device which is connected to the selector and receives the signal from the selected receiving antenna;
• a magnetic field generating unit which causes the magnet to act, thereby generating an induction magnetic field for moving the encapsulated medical device in a target direction;
• and
• a control unit which controls a signal generated by the magnetic field generating unit,
• wherein the control unit specifies the receiving antenna in which an overload current flows by the magnetic field for guidance, and controls the selector to separate the receiving antenna from the receiving device.
