[Limiting resolution of X-ray computer tomography in examination of man].
It is shown as necessary to increase the intensity of radiation source by at least 20 times in order to ensure a 2-fold enhancement of resolution. It predetermines the permissible values of dose per object, which in their turn, condition the permissible values of quantum noise per image (tomogram) as well space and density resolutions. The dose, when intensified purposefully in order to enhance the tomography image resolution, is apparently a limitation for examination of man by X-ray computer tomography.
