Patent ID: 8352016

Claim:
Method for carrying out data collection on electrodes placed on a body for subsequent processing of an electrical impedance tomography image of a corresponding part of the body by means of a reconstruction algorithm, the method comprising the steps of: placing the electrodes on a peripheral line around the body; applying a current pattern from a current source to at least one pair of electrodes; measuring differential potentials between pairs of electrodes; selecting the pairs of electrodes so that at least one intermediate electrode lies in between each pair of electrodes for measuring the differential potentials; selecting the pairs of electrodes so that the at least one intermediate electrode is part of another pair of electrodes for measuring the differential potentials; using the differential potentials of one current pattern for the subsequent image processing from at least three different pairs of electrodes with no electrode used more than twice for each current pattern; and accounting for spatial overlap information in the data collection by the reconstruction algorithm.
