Abstract

A fast and robust finite volume solver of two-dimensional induced current electrical impedence problem was developed. The solver was used to theoretically examine the sensitivity of the impedence technique for monitoring brain cryosurgery. Simulation was performed using a two-dimensional approximation of otherwise realistic geomtery model of the head. The sensitivity of the scalp potential to the ice-ball size was found to be 53 × 10-4.
