摘要：

The suitability of a long-range transmitter was evaluated for use with a Polhemus Fastrak(R) magnetic tracking device in kinesiologic studies. Performance was judged by comparing positional and rotational accuracy to a standard transmitter. Data were obtained at distances of up to 2.7 and 5.0 m for the standard and long-range transmitters, respectively. Use of the long-range transmitter improved system performance allowing reproducible measurements at a greater distance. However, it is necessary to calibrate the system in each new test environment as there can be significant distortion of the magnetic field. (C) 1998 Elsevier Science Ltd. All rights reserved.
