| Summary: | Title screen The article describes a theoretical study of the simplified implementation of dual energy technique (DET) for computed tomography (CT). The implementation is based on the X-ray pre-filter. Two sets of projections, acquired for two maximal X-ray energies, are transformed to the projections of DET parameters. The density and effective atomic number of the test object fragments are estimated after a separate recovery of the internal structure of the test object for each of the DET parameters. The choice of pre-filter thickness is discussed. An example of the initial projections simulation and the estimation of the internal structure of cylindrical objects are shown.
