Craniocerebral Modeling and Experimental Research in Magnetic Induction Tomography System Based on the Agar Model
Magnetic induction tomography(MIT) is a noninvasive and contactless electromagnetic biomedical imaging method.In this paper, A hierarchical model of cerebral hemorrhage was established and put into the MIT system to do experimental study.Firstly, a magnetic induction signal detection system was established.Then a layered model of intracerebral hemorrhage was produced using agar and NaCl solution, the conductivity of NaCl solution was 0.2S/m in endocranium, and the conductivity was 0.02S/m in skull, and the proportion of agar and NaCl solution was 0.8g:100mL.Finally, the simulation lesions which liquid volume is 4mL were put into the hierarchical model of brain to do experimental study.The results show that the data measured from the hierarchical brain model are significantly less than the data from the non-hierarchical brain model.The experimental results demonstrate that the skull has an impact on the size of detected signals of MIT but not the change trend of the measured signals, which indicates that the skull can be used in MIT non-destructive measurement.
