- Abstract
- Under the assumption that the anatomical structure of the head is known, a two-dimensional finite element (FE) model was developed to reconstruct the skull resistivity by using the Newton-Raphson method. The resistivities of scalp and skull, including sutures, are reconstructed based on the condition that the resistivities of the brain, the lower part of the head and the neck as well as the body are known from previous determination in vitro as a priori information. The effect of error in a priori information on the reconstruction is also studied. Reconstructions are compared for two different current injection patterns.
