[Current methods and means of reconstructive tomography (x-ray scanning)].

As the number of detectors per a layer grows, that of the matrix elements increases and the size of the transmitted elements diminishes the devices for reconstructive transmission (x-ray) tomography approach by their informativeness that of the ordinary tomographs, but being appreciably superior to the latter by the number of transmitted contrast gradations. In both cases the X-ray load on the patients is practically the same.
