ABSTRACT A method of imaging the interior of a structure - for example, a mineral body, human body, or the like - having regions therein which differentially affect particular characteristics of electrical signals transmitted through the body. The method involves injecting a plurality of electrical signals into the body, measuring at least one characteristic of each such signal at a plurality of locations, comparing the or each such characteristic as measured with the corresponding characteristic measured at one or more reference point upon or within the structure and generating comparison signals, iteratively reconstructing the impedance spatial relationships between the regions within the structure by utilizing the aforesaid comparison signals, and providing an image of the interior of the structure from the reconstruction of such impedance spatial relationships. The method of the invention provides images which would otherwise be obtainable only through such techniques as X-ray and ultrasonic scanning with their attendant disadvantages.
