Abstract :
The aim of this study is to achieve a noninvasive imaging system of the temperature patterns in the human head using temperature dependence of permittivity. The reconstruction of temperature patterns in the brain model is presented using the capacitance measurement method. In this paper, the method is improved to compensate for scarcity of data. The reconstruction of temperature rise in the cylindrical head model is demonstrated using the improved method. The spatial resolution has been improved. It has been also suggested that the detection of the temperature rise in the brain was possible by using the temperature change pattern in the skull region if the temperature at a point in the brain changes.
