Data taken for EIT imaging on three conductive mortars. Methods A and B were preliminary work. One cylinder with an inclusion as well as the homogeneous cylinder were measured for difference imaging. A total set of measurements was taken for method C. In the case of method A it should be noted that since previous work showed that the resistance between two gel electrodes was related to the time since application of the electrodes, so in this case the electrodes were allowed to sit for five hours before measurements. Data is left in the format produced by the KHU Mark 2.5 device. The relevant files are the XScan.text ones. The first two columns give information about the stimulation and measurement protocol. Column 3 gives Re voltage and column 4 gives Im voltage. Multiple XScan.txt files reflect the multiple sets of measurements that were taken for averaging.
