%0 Journal Article %T EIT Reconstruction Algorithms: Pitfalls, Challenges and Recent Developments %A William R. B. Lionheart %J Physics %D 2003 %I arXiv %R 10.1088/0967-3334/25/1/021 %X We review developments, issues and challenges in Electrical Impedance Tomography (EIT), for the 4th Workshop on Biomedical Applications of EIT, Manchester 2003. We focus on the necessity for three dimensional data collection and reconstruction, efficient solution of the forward problem and present and future reconstruction algorithms. We also suggest common pitfalls or ``inverse crimes'' to avoid. %U http://arxiv.org/abs/physics/0310151v2
