Abstract: An electrode assembly for electrical impedance tomography comprising a plurality of different electrode modules, each containing a support strap made of a flexible material that presents a reduced longitudinal deformability and carrying a predetermined number of electrodes, each support strap being dimensioned to be seated and retained onto a respective extension portion of a body segment of a patient. Each electrode module presents the number of electrodes and a distance “De” between each two consecutive electrodes predetermined as a function of a specific operational pattern to be obtained from each electrode module. The assembly can further comprise an electrical conducting cable having an end connected to a monitoring apparatus and a free end provided with a connector to be coupled to a respective electrode of an electrode module.
