摘　　要：当前,体内微型介入式诊疗装置发展迅速,然而其在人体中的精确定位问题一直未得到很好地解决。提出了基于场源离散化方法的体内微型诊疗装置的交流激磁定位模型,从仿真和试验结果来看,本方法建立的电磁定位模型较其他定位模型相比更精确,更符合实际情况。因此,由该模型得到的体内微型装置的位置误差小,从而可以真正地满足微型诊疗装置在人体内的定位。Today, micro diagnosing and treating devices develop fast. But the positioning problem has not been solved. A positioning model of micro devices in vivo was put forward 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.
