Abstract

We present a proposal and proof-of-concept, experimental results for a new type of electrical impedance tomography / spectroscopy system that makes use of code division multiplexing to achieve two important technological advances. Assigning each channel an orthogonal code allow all the impedance measurements to be made simultaneously in time, thereby increasing the frame rate; and the use of pseudorandom input signals allows a very wide range of frequencies to be sampled simultaneously in each channel.
