VERFAHREN ZUR ABBILDUNG EINES OBJEKTS UND VORRICHTUNG ZUR DURCHFÜHRUNG DES VERFAHRENS

摘要

The method involves impressing electrical current or electrical voltage into an object (2) via an electrode (3). Reaction of the object to the impressed current or voltage is detected by a sensor (6). An image of the object is reconstructed from the detected data. Pulses of the current or voltage are generated by a current source (4) or voltage source (4'). Acoustic waves (5) emitted from the object is detected based on thermal expansion of the object by absorbed electrical energy density of the pulses. Spatial electrical conductivity of the object is reconstructed from the data. An independent claim is also included for a device for executing a method for reproducing electrical conductivity of an object.
