Abstract

In an apparatus for examining living tissue by means of X-rays and by electric impedance measurement, a control device optionally activates an X-ray source and a radiation receiver, and/or for applying current or voltage signals to the tissue to be examined and a unit for measuring induced potentials or currents. This allows an X-ray image to be produced and induced potentials and currents to be measured either simultaneously or sequentially. It is also possible to fuse the respective images produced in these ways.
