TLDR
In this article, a method to obtain images of electrical resistivity within body segments, which is directly applicable to cranial imaging in the newborn, was proposed, based on sensitivity measurements and uses a weighted back-projection algorithm.Abstract:
We propose a method to obtain images of electrical resistivity within body segments, which is directly applicable to cranial imaging in the newborn. The method is based on sensitivity measurements and uses a weighted back-projection algorithm. Preliminary results from a laboratory phantom are presented.read more

Imaging spatial distributions of resistivity using applied potential tomography
TL;DR: The measured values of electrical resistance for various tissues cover a fairly wide range (see as discussed by the authors for some typical values measured using isolated tissue samples) and Table 1 gives some typical electrical resistance values measured with isolated tissue sample.
