Three-dimensional localization system for intra-body microcapsule based on alternating magnetic field / 生物医学工程学杂志

ABSTRACT

In order to determine the position of an intra-body microcapsule, the system based on alternating magnetic field has been promoted. According to the theory of three-dimensional localization system, the mathematical model has been ratiocinated. Composing and software design of the system are given. The result of the experiment has demonstrated that the system is feasible and it performs with high precision. The position error is less than 3 cm when the range is between 3 and 30cm. And the system has good anti-interference ability.
