The accurate magnetic localization and orientation technique has dramatically enhanced the applications of capsule endoscope for the gastrointestinal (GI) tract examination. Yet, the surgical robot has been hindered to use widely due to the limitations of current surgical navigation technique. In this paper, an electromagnetic navigation system based on coils and magnetic sensor is introduced. The...
The location and orientation of the wireless capsule endoscope inside the human body is very important for the gastrointestinal (GI) examination. To satisfy the requirement of the position and gesture information of endoscope, a magnetic localization and orientation system is built. The system uses a permanent magnet as excitation source to create the magnetic field, and consists of a magnetic sensor...
To track the movement of wireless capsule endoscope in the human body, we design a magnetic localization and orientation system. In this system, capsule contains a permanent magnet as the movable object. A wearable magnetic sensor array is arranged out of the human body to capture the magnetic signal. This sensor array is composed of magnetic sensors, Honeywell product HMC1043. The variations of magnet...
To track the movement of a wireless capsule and get the 6D localization and orientation information of the capsule, a magnetic localization and orientation system is designed. In this system, we propose to enclose two orthogonal permanent magnets in the capsule. With the magnetic sensor array arranged out of the human body, we can measure the magnets' magnetic signals, and compute the magnets' 3D...
