  This document reports an Open 2D Electrical Impedance Tomography (EIT) data
set. The EIT measurements were collected from a circular body (a flat tank
filled with saline) with various choices of conductive and resistive
inclusions. Data are available at http://fips.fi/ EIT_dataset.php and can be
freely used for scientific purposes with appropriate references to them, and to
this document at https://arxiv.org. The data set consists of (1) current
patterns and voltage measurements of a circular tank containing different
targets, (2) photos of the tank and targets and (3) a MATLAB-code for reading
the data. A video report of the data collection session is available at
https://www.youtube.com/watch?v=65Zca_qd1Y8.
