A one step image reconstruction algorithm for electrical impedance tomography in three dimensions.

The move from two to three dimensions in the study of electrical impedance tomography (EIT) has generated a great increase in computational demands. It is therefore interesting to investigate ways in which this demand can be reduced, and in this paper we have presented some results of one such approach. The NOSER algorithm was introduced some years ago and we have extended it to include more realistic electrode models. The main feature of the method is that by starting from a uniform conductivity distribution many quantities can be pre-calculated.
