APTD

The Applied Potential Tomography device is based on a non invasive method of imaging biological structures by measuring electrical properties of the tissues in cross sectional planes of the body.

The basic principle of this technique is an injection of alternating electrical current and the measurement of the resulting potential differences by a circular array of electrodes attached to the surface of the object.

Reconstruction algorithms, implemented in the Data Management System are used to calculate the spatial distribution of electrical properties (e.g. impedance) within the cross section under study.

Depending on a single frequency shot or a multi frequency ones, different parameters characterizing the fluid volume and shift studies can be accessed.
