description: The given work is devoted to a comparative evaluation of radiation therapy plans in terms of target dose coverage and radiation loads on critical structures performed with and without iMAR CT artifact correction algorithms. As part of the work, CT scans were performed and two series of images were generated - native and with application of metal artifact suppression (iMAR). Dosimetric calculation of radiation therapy plan was performed followed by dose calculation. Dose volumes with and without application of IMAR algorithms were then compared. The results showed that there were no significant differences in dose distribution coverage of the target volume and loads on critical structures, which allows us to recommend the use of CT with metal artifact correction using iMAR algorithms in dosimetric planning of distant radiation therapy. The results of this study helped to determine the adequacy of CT image artifact correction using iMAR algorithms, and they can be implemented in the clinical practice of radiotherapy departments.
