Primary Study on Dielectric Property Detection for Cerebral Haematoma

It´s found that the distinction of permittivity of different tissues is more obvious, according to analyzing the changing regularity of the conductivity and permittivity of the head tissue at different frequency. A capacitance measuring method based on dielectric property is presented, which aims at detecting the haematoma as well as its development expediently. According to the head structure, a multi-layer head model is built up with ANSYS analysis software. The different states of haematoma such as the position, size and the extent of approaching the measuring electrode are analyzed in two-dimension model. The feasibility of the measurement is proved.
