Abstract

Presents a two dimensional 16 electrodes electrical impedance tomography (EIT) system, that the authors are developing by using an electronic circuit for adaptive voltage measurement, in order to apply it to epilepsy research. Simulations of epileptic status and other brain pathologies are simulated by using the RC circuit phantom (see J. Rosell et al., Proc. 11th Int. Ann. Conf. IEEE Eng. in Med. and Biol. Soc., Seattle, vol. 11 p. 459-60, 1989)
