1. An electrical capacitance tomography (ECT) system comprising: a plurality of ECT sensor heads, each ECT sensor head including: a plurality of electrodes disposed about a measurement region, first circuitry configured to measure mutual capacitance between a plurality of pairs of electrodes of the plurality of electrodes and obtain a plurality of mutual capacitance measurements, and a first wireless transceiver coupled to the first circuitry and configured to transmit the plurality of mutual capacitance measurements; and an ECT reader including: a second wireless transceiver configured to selectively communicate with each of the ECT sensor heads to receive the plurality of mutual capacitance measurements, and second circuitry including a fuzzy logic image synthesizer configured to process the received plurality of mutual capacitance measurements and produce an image corresponding to contents included in the measurement region.
