Spatial resolution of high-energy computed tomography is experimentally studied on the basis of X-ray inspection of a steel cylinder to assess the operability of the system [1, 2]. To determine the spatial resolution in the energy range of X-ray radiation from 1 to 4 MeV, the modulation transfer function with a preliminary filtering of radiation by a copper plate of 4 mm thickness was measured. The effect of beam hardening and correction of ring artifacts is studied. The modulation transfer function is determined using the Brucker microCT software. Experimental studies were conducted in the Russian-Chinese scientific laboratory for X-ray control and inspection of the Tomsk Polytechnic University [3, 4].
