Apparatus to scan mammary tissue for tumors has an electrode array shrouded by a conductor at least in zones which is supplied with a different and lower potential from the potential at the electrodes to eliminate edge effects

摘要

The apparatus to scan human tissue, especially for the detection of a tumor, has an array of electrodes supplied with a current and/or voltage with a system to give measurements from at least one electrode. The electrode array is shrouded by a conductor, at least in zones, which is supplied with a different and lower potential from the potential at the electrodes. The conductor (2) is a metal or plastics element.
