Jin, Jianming Chen, Ji 2015-09-25T20:10:18Z 2015-09-25T20:10:18Z 10000-01-01 1998 1998 In this thesis, these three techniques are used to investigate the interaction between the electromagnetic field and a human head. The FEM finds its efficient application in solving small but very complicated problems. The MoM-based biconjugate fast Fourier transform (BCG-FFT) technique, which dramatically reduces the computational memory requirement and the computational time, is employed to analyze the open RF coils in an MRI system. The FD-TD method, known for its ability to handle large and complex geometries, is applied to shielded birdcage coil analysis. Besides studying the field information inside the human head, the RF coil's resonant frequency shift due to the biological loading and the SNR of RF surface coils are also investigated in this thesis. It is expected that the EM solver can be combined with the heat transform equation to simulate the heating pattern inside biological objects. The EM solver can also be applied together with Bloch's equation to provide more detailed pictures of the NMR phenomenon. Made available in DSpace on 2015-09-25T20:10:18Z (GMT).
