The present application is a system for use in creating images of portions of human tissue inside the body by electrical impedance tomography. The system (10) may comprise at least one flexible tube (11) for insertion in the body in proximity to a targeted portion (20) of human tissue in the body, an inflatable balloon (12) removably attached to the distal end of the flexible tube, a first array of electrodes (13) attached to the surface of the inflatable balloon for at least one of injecting current into the targeted portion of human tissue and receiving current that was injected into the targeted portion of human tissue, and a second array of electrodes (17) for at least one of injecting current into the targeted portion of human tissue to the first array of electrodes and for receiving current from the first array of electrodes.

La présente invention a trait à un système destiné à la création d'images de portions du tissu humain dans l'organisme par la tomographie à impédance électrique. Le système (10) peut comporter au moins un tube flexible (11) pour l'insertion dans le corps à proximité d'une portion ciblée (20) de tissu humain dans le corps, un ballonnet gonflable (12) fixé de manière amovible à l'extrémité distale du tube flexible, un premier réseau d'électrodes (13) fixé à la surface du ballonnet gonflable pour l'injection d'au moins un courant dans la portion ciblée du tissu humain et la réception de courant qui a été injecté dans la portion de tissu humain, et un deuxième réseau d'électrodes (17) pour l'injection d'au moins un courant d'injection dans la portion ciblée de tissu humain au premier réseau d'électrodes et pour la réception de courant en provenance du premier réseau d'électrodes.
