介入式微型医疗装置电磁定位方法的可行性研究
Research on the feasibility of localizing in-vivo micro-devices with electromagnetic methods
为了跟踪胃肠道内介入式微型医疗装置的位置，考虑到人体介质的非导磁性，提出了基于电磁场理论的定位方法。主要研究了两种类型的电磁定位方案：一种方案采用直流激励产生静态电磁场，另一种方案采用交流激励产生交变磁场。分析了两类方案的定位原理，并搭建了实验平台，完成了相关的实验研究。实验表明：交流励磁定位方案比直流励磁定位方案具有更高的精度、更优的稳定性、更宽的测量范围。
In order to measure the location of medical micro-devices in the gastrointestinal tract, electromagnetic methods were developed considering the magnetic permeability of human bodies. Two varieties of electromagnetic localization methods have been implemented: one used direct current to generate the electromagnetic field, and the other uses alternating current. The two varieties of the localization principle were analyzed and relevant experiments were made. The experiments show that the alternating electromagnetic method acquires higher accuracy, higher stability and wider measurement range.
