Abstract:
In this paper, a new imaging method to determine the position of blood effusions or edemas in the deep position of the brain by using electric current flowing through the brain is presented. Its principle is that the existence of non-normal matters in the brain cause a disturbance to boundary potentials, while a low frenqency current flows through the brain. In terms of the measurement for the change value of boundary potentials a reconstruction for the blood effusion or the edema in the deep position of the brain can be done.
