Эти исследования зачастую осуществляются с помощью таких мелких лабораторных животных, как мыши и крысы, поэтому возникает вопрос об этических проблемах международного характера. В связи с этим актуальным является применение искусственных моделей животных, что позволит сократить количество используемых животных. В ранее проведенных исследованиях были изготовлены гомогенные монолитные тестовые объекты и проведены их дозиметрические испытания. Были определены параметры и материалы печати для наиболее точной имитации биологических тканей. В данном исследовании предлагается использовать методы трехмерного изготовления для разработки и изготовления гетерогенных объектов из различных материалов, что позволит создавать фантомы с высокой точностью за короткий срок. В работе был разработан и изготовлен дозиметрический фантом самца крысы. Были проведены его томографические и дозиметрические испытания. Была показана возможность изготовления дозиметрических фантомов мелких лабораторных животных методами трехмерной печати.</p></abstract><trans-abstract xml:lang="en"><p>In order to validate new radiotherapeutic techniques, a large number of studies using ionizing radiation are required. Such studies are often carried out using small laboratory animals, such as mice and rats, that is cause the ethical questions of the international scientific community. In this regard, the application of artificial animal models is relevant. It is allow to reduce the number of animals used. In previous studies, homogeneous monolithic test objects were fabricated and dosimetric tests were performed. 3D-printing parameters and materials were determined for the most accurate imitation of biological tissues. This study proposes to use fused filament fabrication techniques for design and creation of heterogeneous objects from different materials, which will allow the fabrication of phantoms with high accuracy in a short period of time. In this work, the male rat dosimetric phantom was designed and created. Its tomographic and dosimetric tests were carried out. The possibility of manufacturing dosimetric phantoms of small laboratory animals by fused filament fabrication methods was shown</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дозиметрия</kwd><kwd>дозиметрический фантом</kwd><kwd>3D-печать</kwd><kwd>метод послойного наплавления</kwd><kwd>пленочные дозиметры</kwd><kwd>дозное распределение</kwd><kwd>компьютерная томография</kwd><kwd>гамма-аппарат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dosimetry</kwd><kwd>dosimetric phantom</kwd><kwd>3D printing</kwd><kwd>fused filament fabrication method</kwd><kwd>dosimetry film</kwd><kwd>dose distribution</kwd><kwd>computed tomography</kwd><kwd>gamma machine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Российского научного фонда (проект № 23-79-01232)</funding-statement><funding-statement xml:lang="en">The work was carried out with financial support from a grant from the Russian Science Foundation (project no. 23-79-01232).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каприн А.Д, Старинский В.В., Шахазадова А.О.
