Публікація Analysis of radiation therapy equipment status in Ukraine(Innovative technologies and scientific solutions for industries, 2020) Averyanova, L. A.; Starenkiy, V.The subject matter of the article is review and analysis of existing radiation treatment technologies, availability and efficiency of use of modern radiotherapy equipment in regions Ukraine according to European radiotherapy development trends. The goal of the work is to analyze the current status of radiotherapy equipment in Ukraine and to find the ways for extension of its use. The following tasks were solved in the article: the analysis of distribution of radiotherapy machines in Ukraine, estimation of current number of radiotherapy machines per million people for all regions and needs of radiotherapy centers of Ukraine in high precision conformal treatment machines. The following methods used – documentary data analysis, comparison and summarizing. The following results were obtained – estimated that according to requirements of IAEA that necessary number of megavoltage treatment machines in Ukraine should be near 200. Use of 90 machines covers only 45% needs of Ukrainian population in radiation treatment. According to DIRAC data 61 of 65 Co-60 machines in Ukraine are used during more than 20 years, Co-60 sources in 23 these machines now have Dose rate less than 0.4 Gy/min and must be replaced urgently. Conclusions: The main actual aspects of technical status of equipment for External-beam radiation therapy in Ukraine were discussed. Existing radiotherapy facilities were analyzed from the point of view of real needs and possibilities of Ukrainian radiation oncology. As a conclusion, the results of this analysis demonstrate a significant heterogeneity in the access to modern radiotherapy equipment in different regions of Ukraine. The qualitative analyses of used radiotherapy equipment demonstrate its significant technical backwardness. The results of this analysis may be used as technical recommendations for improvement of radiotherapy facilities in Ukraine.Публікація Detrermination of the true dimentions of a cylindri cobject fromits X-ray photograph(Москва, 2001) Averyanova, L. A.; Golovenko, V. M.; Скляр, О. І.In clinical practice X-ray photographs are often used not only for the qualitative analysis of the images of objects, but also for the determination of some object dimensions. When acquiring an X-ray photograph one should always consider a projection magnification, due to which the determination of true object dimensions can be difficult. This magnification arises due to the finite radiator dimensions, finite distance to the object and between the object and the radiator. This can also happen if the object and radiator dimensions are comparable. If one has to make certain measurements on the X-ray photograph and then to calculate some values from these measurements, errors due to the projection distortion of each measured object arises (fig. 1). For instance, in X-ray morphometry of tubular bones it is necessary to measure the inner and outer diameters of the metacarpal bone when calculating osteoporosis indices. At that the projection distortion of every bone layer is different (Δr, ΔR).Публікація E-Learning of Functioning Principles Medical Intrascopy Systems(Varna, Bulgaria, 2007) Аврунін, О. Г.; Averyanova, L. A.; Golovenko, V. M.; Sklyar, O.Principles of E-Learning Medical Intrascopy Systems are described.Публікація The experience software-based desine of virtual medical intrascopy systems for simulation study(International Journal "Information Technologies and Knowledge", 2008) Аврунін, О. Г.; Averyanova, L. A.; Golovenko, V. M.; Скляр, О. І.Created virtual intrascopy systems allow carry out imitation experiments. Use of e-leaning means is effective method for training of bio-engineers and physicians. These systems may be additional leaning means at study of any high-end technology apparatus.The perspective of this work is design software for creating virtual operation room with several intrascopy systems and modern surgical tools models for surgical planning. This technology is very actually, for example, for neurosurgery planning. This special software will allow surgeon to simulate operation process and choose small-invasive surgical access.Публікація The Idia of Monitoring Mass Population Bone System Checkups(2001) Averyanova, L. A.; Golovenko, V. M.; Скляр, О. І.; Sharmazanova, E. P.In great extent, functional abilities of a human organism are determined by the state of its bone system. The extent, to which the bone pathology has spread, has become one of the most vital medical and social problems of the modern society. To catalyze investigations on the prophylactics, diagnosis and treatment of the bone system diseases, the W.H.O. has declared a decade of bones and joints (2000-2010).
