This section needs additional citations for verification. The Feynman Lectures on Physics, Vol. The principles involved are similar to seismologyexcept GPR methods implement electromagnetic energy rather than acoustic energy, and energy may be reflected at boundaries where subsurface electrical properties change rather than subsurface mechanical properties as is the case with seismic energy. For soft tissue, photoabsorption dominates up to about 26 keV photon energy where Compton scattering takes over. In other projects Wikimedia Commons. This allows the photon energy to be adjusted for the application so as to give sufficient transmission through the object and at the same time provide good contrast in the image.
