ABSTRACT:
The present invention concerns a method of calibrating a tomographic system which is used for testing earthen cores. At least two phantoms of a first type of phantom is used in calibrating for contrast resolution. At least two phantoms of a second type of phantom are used to calibrate the tomographic system for beam hardening.
