The digital images quality estimating methods that are distorted by artifacts are considered. The most common types of artifacts are artifacts due to increased beam stiffness, the effect of partial volume filling, arbitrary patient movements during examination, etc. Quantitative and subjective measures are used to evaluate the quality of digital images. A comprehensive evaluation of the quality of tomographic images is proposed, based on the combination of the two above metrics, which will allow to better evaluate the quality of the tomographic image and to automate the evaluation process itself. A technique for evaluating the quality of tomographic images has been developed, which will allow for a more accurate diagnosis by eliminating the subjectivity of the physician.References
