title: [Substantiation of requirements for basic informative characteristics of tomograms].
abstract: In order to estimate the clinical efficiency of the method of layer-by-layer roentgenography a comparison of the apparatus with different translocation trajectories of the tomographic system has been made. The efficiency of the tomographs was appraised by such parameters as: coefficient of purity, thickness of the section and the degree of blurring. Investigations showed that the circular trajectory is to be preferred to the non-linear one. The adoption of such a trajectory enables it to simplify the design of the non-linear tomograph, makes it less costly and convenient in handling.
