The Electrical Transimpedance Scanning is a new modality of image based on the differences in electrical properties of tissues. It is an extremely promising technique to complement other conventional image examinations. Areas presenting abnormalities and/or malignant neoplasia evidence exhibit conductive changes that cause an impedance variation between cancerous ant health tissues. Since there are very few commercial devices available that use the new Electrical Transimpedance Scanning technology, this paper describes the design of a prototype using this technique aiming to contribute somehow in the evaluation of the parameters involved.
