In this paper, an electromagnetic tracking method based on fast determination of the maximum magnetic flux density vector (MMFDV) represented by two azimuth angles is proposed. The system designed to validate this method includes two magnetic sources and a 3-axis magnetic sensor. Each source consists of three mutual orthogonal coils. The main characteristic of this method is that the direction of...
This paper presents an electromagnetic tracking method based on two electrically-controlled magnetic sources. Each source consists of three mutual orthogonal coils. The method can skillfully determine the rotation angles of the maximum magnetic flux density vector (MMFD V) generated by a magnetic source according to the Biot-Savart Law. Then the position of the sensor can be calculated with a noniterative...
In this paper, an electromagnetic tracking method that uses two rotating orthogonal coils is proposed. Two cross-shaped coils can rotate together and be driven in sequence to generate a magnetic field. One of the rotating orthogonal coils is used to track the position of the three-axis sensor and the other is to help solve the orientation of the sensor. As rotation can provide a geometrical relationship...
