Electrode assembly for electrical impedance tomography

摘要

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.

1. An electrode assembly for electrical impedance tomography (EIT), the electrode assembly comprising:
an electrode belt having a plurality of EIT electrode modules configured to couple together longitudinally and configured to couple with an EIT monitoring apparatus configured to generate an EIT image responsive to signals received the plurality of EIT electrode modules, wherein each EIT electrode module of the plurality of EIT electrode modules includes:
a support strap having a first end with a coupling element and a second end with a coupling receiving element, wherein the coupling element of one EIT electrode module is configured to couple longitudinally with the coupling receiving element of another EIT electrode module to form the electrode belt; andEIT measurement electrodes attached to the support strap in respective fixed positions; wherein at least two EIT electrode modules of the plurality of EIT electrode modules of the same electrode belt have a different spacing of the EIT measurement electrodes for a non-uniform distribution of the EIT measurement electrodes along at least a portion of the electrode belt.
