基于场源离散化方法的体内微型诊疗装置定位模型及验证

oday, micro diagnosing and treating devices develop fast. But the positioning problem has not been solved. This paper put forward a positioning model of micro devices in vivo, based on the discrete method of source of magnetic field. From the result of simulation and experiments, the positioning model is so accurate that can visualize the real magnetic field. Because of small positioning error, which is computed according to the algorithm derived from this positioning mode, the positioning model and method is much more feasible and expected to put into practice in medical application.
