Spatial resolution Compton of systems

The various algorithms of definition of a spatial rule of border of two environments with different density are investigated for reconstruction of distribution of density on backscatter radiation (in Compton tomography). The real missing beams, range of energy 10-1000 keV and various materials are considered. The algorithm based joint processing of functions, N(x) change of number of quantums N in the detector, is offered at change of coordinate x of disseminating volume and its by derivative /spl part/N//spl part/x. The algorithm is steady for a wide class of materials and provides an error of definition of a rule of border of two environments no more than /spl plusmn/0.1 mm.
