The Problems and Perspectives of Megavoltage Photon Beam Radiotherapy in Ukraine.Problems of Atomic Science and Technology, 2016, N3(105), P.50-54http://openarchive.nure.ua/handle/document/4100The methods of X-ray computed tomography being improved every year and we have a sufficient amount of methods and tools for high-quality visualization at that very moment. However, as practice shows, there are still low quality CTs (with the presence of strongly pronounced artifacts) in the developing countries. The quality of the scans is of great importance in radiotherapy planning. An incorrect mapping of the density distribution will distort isodoses calculation. In the present article, we will consider the impact magnitudes of the beam hardening artifacts on the radiotherapy planningenradiotherapy planning, CT, artifactArticle
