description: The subject of the graduate qualification work is âResearch on the applicability of modern algorithms for calculations with wedge-shaped filtersâ. The research set the following goals: 1. Investigate the principles of calculating the dose of collapsed cone algorithm 2. Consider the principle of calculating wedge-shaped filters collapsed cone. 3. Compare the results of calculations in the Monaco planning system with exÂ¬perimental data. 4. Draw conclusions about the possibility of clinical use of the algorithm using wedge-shaped filters. The work was fulfilled on the premises of GBUZ "St. Petersburg clinical sciÂ¬entific and practical centre for specialized medical care (oncological)" which inÂ¬cluded collection of factual materials, percentage depth doses were measured using wedge-shaped filters for the Siemens Primus linear electron accelerator No. 3487. Measurements were made using the method of ionization dosimetry. The study resulted into, the dose estimation uncertainties associated with the use of wedge-shaped filters were determined and calculated. Further, these uncerÂ¬tainties were taken into account in the algorithm for calculating the Collapsed Cone. Calculated percentage dose measurements for a set of wedge-shaped filters in the MONACO planning system were compared with experimentally obtained measurements on the Siemens Primus accelerator No. 3487. Conclusions were made about the possibility of applying the Collapsed Cone algorithm with wedge-shaped filters in medical practice.
