Для машинного обучения модели проведен ретроспективный анализ данных для 40 пациентов с патологиями грудного и поясничного отделов позвоночника. Для каждого пациента создан план распределения дозы излучения методом стереотаксической лучевой терапии с помощью инверсного метода моделирования с дозовым режимом фракционирования 6 Гр по пять фракций. Проведена оценка производительности созданной модели на тестовой выборке из 10 пациентов. Результаты верификации подтверждают пригодность модели для клинического применения в учреждениях здравоохранения онкологического профиля и перспективность ее использования для создания персонализированных планов лечения. Автоматизация процесса предлучевой подготовки позволила сократить временные затраты на компьютерное моделирование трехмерного распределения дозы ионизирующего излучения и повысить качество оказываемой специализированной медицинской помощи методом стереотаксической лучевой терапии.</p></abstract><trans-abstract xml:lang="en"><p>The automation of the radiotherapy preparation process is demonstrated through the development and machine learning of a multi-criteria ionizing radiation dose distribution model, using artificial intelligence tools embedded in the RapidPlan module of the Eclipse v16.1 (Varian Medical Systems) treatment planning system. A retrospective data analysis of 40 patients with thoracic and lumbar spine pathologies was performed to train the model. For each patient, a radiation dose distribution model was created using stereotactic radiation therapy with an inverse planning method and a dose fractionation regimen of 6 Gy in 5 fractions. The performance of the developed model was evaluated on a test set of 10 patients. Verification results confirm the model’s suitability for clinical application in oncological healthcare facilities and the prospect of using it to create personalized treatment plans. Automation of the pre-radiotherapy preparation process reduced the time spent on computer modeling of the three-dimensional ionizing radiation dose distribution and improved the quality of specialized medical care provided by stereotactic radiation therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многокритериальная модель</kwd><kwd>автоматизированное моделирование</kwd><kwd>трехмерное дозовое распределениe</kwd><kwd>ионизирующее излучение</kwd><kwd>модуль RapidPlan v16.1</kwd><kwd>компьютерная система планирования облучения Eclipse v16.1</kwd><kwd>машинное обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multi-criteria model</kwd><kwd>automated modeling</kwd><kwd>three-dimensional dose distribution</kwd><kwd>ionizing radiation</kwd><kwd>RapidPlan v16.1</kwd><kwd>treatment planning system Eclipse v16.1</kwd><kwd>machine learning</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">The efficacy of external beam radiotherapy and stereotactic body radiotherapy for painful spinal metastases from renal cell carcinoma / G.
