摘要：

A new approach to image reconstruction problems is proposed to improve results applying the level set technique during a reconstruction process that is based on electrical impedance tomography (EIT). Recently described methods are often based on deterministic or stochastic approach to solve EIT inverse problem, which is nonlinear and highly ill-posed. The suggested approach combines advantages of nowadays used deterministic methods such as Tikhonov regularization method with advantages of the level set method. A new way is applied to the tissue conductivity reconstruction. Numerical results of the improved image reconstruction based on the proposed new technique are presented and compared with previous results. © 2010 Institute of Thermomechanics AS CR, v.v.i.
