Fast algorithm of reconstruction of absolute conductivity distribution in a cross-section of human body by measurements of electrodes' potentials on the skin surface is described. ... This paper describes fast algorithm for absolute conductivity reconstruction and results of its application. ... The main problem under the absolute image reconstruction is obtaining of reference data, corresponding to the object with uniform conductivity and the same electrode positions. ...

... the data are described accurately enough to allow an unambiguous interpretation of the data, as well as a comprehension of the context in which the data were acquired and/or processed; a single ascii file, named ReadMe , is designed for this role. the data are in a format which allows their usage by tools currently in usage in our discipline -- normally flat ascii files ; other formats can be accepted, but are converted into flat files. ... How to prepare the Data files . ... How to deposit the data...
