摘要

Towards real time imaging of human organs during medical surgeries for organ excision or tumor care, we have been engaged in developing a high-resolution tracking system by using artificial magnetic fields and 3D MEMS magnetic sensor nodes for years. This paper presents fundamentals of this approach, design and simulation of the electromagnetic system for the pursuit of unique magnetic fields with preferable spatial resolution, and configuration of the developed prototypes. The preliminary results reveal that spatial resolution of a few mm can be achieved after applying multi-pairs electromagnetics, which is powered by DC and AC signal respectively for noise cancellation as well as for rotation recognition. Moreover, temperature dependence, background noise of a surgical room, and many other specifications of the developed system were investigated, evaluated, and discussed herein.
