А. С. Гвай, Л. А. Аверьянова

Abstract

The questions of control doses to patients with X-ray computed tomography (CT) are discussed. The physical factors of CT dose index values, which form the basis for the most common method for determining radiation dose in patients with CT, are analyzed. As a result of the shortcomings of this method are analyzed and for its refinement are suggested. Figs.: 1. Tabl.: 1.
