Abstract
Magnetic induction tomography (MIT) could be one of next generation imaging techniques, yet has many challenges in enhancing resolution and sensitivity. Currently, most developed MITs utilizes normal copper electromagnets (EMs) to generate excited magnetic field so that it could be low cost and compact in size but generates weak magnetic strength, difficult in analyzing objects. One of ways enhancing performance is to control magnetic field of transmitter and receiver coils effectively. In this paper, various EM designs and the fundamentals to control magnetic field in open space has been studied. Numerical methods to analyze magnetic field, in general, provide good accuracy but require heavy computation time and resource. Lumped parameter method shows fast computation, but cannot characterize design of EMs. It may not be suitable to design EMs. Thus, in this paper, novel magnetic field modeling method, extended Distributed Multi-Poles (eDMP) modeling method has been used to compute complex magnetic field in real-time and analyze the performance of the MIT. Magnetic field of various EMs has been analyzed and compared to numerical method. Lastly, the eDMP method has been applied for design analysis of EMs of MIT.
