Study on the influence of solid medium on magneto-acoustic-electrical tomography

Magneto-Acoustic-Electrical Tomography (MAET) is a multi-physics coupling imaging technology based on the principle of Hall effect, which can be used to detect the electrical conductivity distribution in tissues. Traditional MAET is considered to occur in soft tissue medium, which is regarded as fluid when calculating. But in fact, there are some solid media in human body that will affect our detection, such as skull. Based on the head, this paper analyzes the influence of solid medium on MAET process. Using finite element software, the influence of skull on sound field and electric field is analyzed firstly, and MAET signal of head considering the skull is obtained. The results preliminarily verify the feasibility of applying MAET to the situation with solid medium.
