Abstract:
1. An electrode belt for use with an Electrical Impedance Tomography (EIT) system, the belt comprising: a core layer comprising a plurality of electrodes spaced along an elongate length of the belt, the electrodes each having a contact face configured to contact and make electrical connection with skin of a portion of a body of a patient under examination; the core layer disposed between a first insulating layer and a second insulating layer, wherein the first insulating layer provides insulation over the electrodes and the second insulating layer does not provide insulation over the electrodes, thereby allowing the electrodes to be exposed on only one side thereof; a first shielding layer disposed over the first insulating layer and a second shielding layer disposed over the second insulating layer, wherein the first and second shielding layers comprise a conductive material thereby providing circumferential active or ground shielding for the belt; a first outer layer disposed over the first shielding layer and a second outer layer disposed over the second insulating layer, the second outer layer including a plurality of apertures corresponding to the electrodes to provide engagement of only one side of the electrodes on the skin of the portion of the body; wherein the core layer, the first and second insulating layers, and the first and second shielding layers are created using a multilayer printing process; and the belt being configured to, in use, extend substantially from one side of the portion of the body of the patient under examination to another side of the portion of the body of the patient under examination without encircling the body of the patient.
