В работе представлены термические эффекты в полиакриламидных биофантомах с бычьим альбумином и цитратной кровью при лазерном облучении на длине волны 970 нм и 1560 нм. Для лазерного облучения использован хирургический двухволновый аппарат (ИРЭ «Полис», г. Фрязино, Россия). Облучение фантома осуществлялось через кварцевое световолокно диаметром 400 мкм с торцевым выходом. Результатом облучения была зона коагуляции, которая визуализирована флуоресцентным органоскопом «FLUM-LL». Термометрия осуществлялась тепловизором FLIRONE PRO for IOS и цифровым термографом Т-8 на базе ноутбука с термосенсорами, размещенными в фантоме. Использование облучения мощностью не более 2 Вт в режиме коагуляции с суммарной дозой энергии до 120 Дж позволяло достигать плавного подъема температуры до 88оС. Зона коагуляции при облучении волной 1560 нм всегда была больше, чем при облучении волной 970 нм, хотя статистически разница была недостоверной (p=0,41). Средняя площадь пятна коагуляции для излучения 970 нм составила 43,2 (39,3 – 47,1) мм2, для 1560 нм – 99,4 (56,5 – 141,3) мм2. При суммарном облучении двумя волнами, зона коагуляции была больше, если преобладала мощность излучения 1560 нм. При облучении волной 970 нм зона коагуляция частично распространяется кзади от кончика световолокна, при 1560 нм – коагулирует фантом кпереди. Полученные результаты имеют практическую значимость при применении лазерной гипертермии внутримозговых опухолей.</p></abstract><trans-abstract xml:lang="en"><p>Laser interstitial hyperthermia is an actively developing direction in intracerebral tumor surgery. The paper presents thermal effects in polyacrylamide biophantoms with bovine albumin and citrated blood under laser irradiation at 970 nm and 1560 nm. For laser irradiation, a surgical two-wave apparatus manufactured by IRE Polis was used. The phantom was irradiated through a quartz optical fiber 400 µm in diameter with an end exit. The result of irradiation of the phantom was its coagulation zone, which was visualized with a FLUM-LL fluorescent organoscope. Thermometry was carried out with a FLIRONE PRO for IOS thermal imager and a T-8 digital thermograph based on a laptop with thermal sensors placed in a phantom. The use of irradiation with a power of not more than 2 W in the coagulation mode, with a total energy dose of up to 120 J, made it possible to achieve a smooth rise in temperature to 88.0 °C. The dimensions of the coagulation zone under irradiation with a wave of 1560 nm were always larger than under irradiation with a wave of 970 nm, although the difference was not statistically significant (p=0,41). Thus, the average coagulation spot area for 970 nm radiation was 43.2 (39.3 – 47.1) mm2, and for 1560 nm – 99.4 (56.5-141.3) mm2. With total irradiation with two waves, the coagulation zone was larger if the radiation power of 1560 nm prevailed. When irradiated with a wave of 970 nm, the coagulation zone partially propagates posteriorly from the tip of the optical fiber, and 1560 nm coagulates the phantom anteriorly. The results obtained are of practical importance for laser hyperthermia of intracerebral tumors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биофантом</kwd><kwd>термометрия лазерного облучения биофантома</kwd><kwd>лазерная гипертермия внутримозговых опухолей</kwd><kwd>режимы гипертермии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biophantom laser irradiation thermometry</kwd><kwd>laser hyperthermia of intracerebral tumors</kwd><kwd>hyperthermia modes</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mohammadi A., Bianchi L., Asadi S., Saccomandi P.
