Comprehention of Coils Overlappings Effects —Magnetic Resonance Imaging

Abstract

A typical medical Magnetic Resonance Imaging (MRI) contains a Local transmit/receive coil. Magnetic coil design is very important in study of the human brain and for neurological therapeutics technique. Precise spatial localization of stimulation sites is the key of efficient functional magnetic stimulations. Others have examined this issue at radio frequencies. This paper develops circular coils, figure-of-8 coils and coil array elements in order to realize a transcranial magnetic stimulator, and analyses the coil properties. The tests are done here with the applied DC excitation. The results show that different coils have different focus. The most important feature of these simulations is the ability to expand it. With these tests, the procedure of construction is determined. I simulate all procedures by MAXWELL 16.0.
