| Abstract: | In this paper, a relative density reconstructing method is suggested. The advantage of this method is that the image of density to be reconstructed does not depend on the efficiency factor of radiation source and factors of detecting system. The constraint condition obtained in this paper is accord with the condition under which the mainly single Compton scattering occurs. |
