摘要：
A two dimensional electrical impedance tomography reconstruction algorithm based on a quasi-Newton method is presented. The algorithm is particularly fast: each iteration, which includes solving the forward problem and updating the inverse of the Jacobian matrix, takes on average 0.11s on a 25MHz 68040 based NeXT workstation. The average number of iterations required for accurate image reconstruction has been found to be 20.
