Авторами предложен способ прямой дозиметрии с использованием оптоволоконного сцинтилляционного дозиметра МКД-04. Дозиметр фиксирован на эндостататах и визуализируется на экранах компьютерного или магнитно-резонансного томографа. Координаты вносятся в анатомические блоки и дозиметрические расчеты, данные сопоставляются, дозы корректируются по медицинским показаниям. Разработанная авторами методика прямой дозиметрии позволяет проводить контроль за процедурой контактной лучевой терапии (КЛТ) в режиме реального времени и вносить необходимые изменения, внося коррективы в ходе проведения лечения. Уточнение величин поглощенных доз с помощью расчета и прямой дозиметрии минимизирует риск осложнений и обеспечивает возможность эффективного использования после КЛТ других методов лечения, в том числе фотодинамической терапии.</p></abstract><trans-abstract xml:lang="en"><p>The use of multicomponent methods of special treatment (surgery, polychemotherapy, radiation therapy, laser photodynamic therapy) in oncology requires the control of doses in the tumor and healthy organs with high accuracy. A method of direct dosimetry using fiber-optic scintillation dosimeter MCD-4 is proposed. The dosimeter is fixed on endostats and is visualized on CT/MRI. The coordinates are entered into the anatomical units and dosimetry calculations, the data are mapped, the doses are adjusted on medical grounds. The developed technique of direct dosimetry allows monitoring of the contact radiation therapy (CRT) procedure in real time and making the necessary changes and corrections during the treatment. The refinement of the absorbed dose values using calculations and direct dosimetry minimizes the risk of complications and ensures the possibility of effective use of other treatment methods, including photodynamic therapy, after CRT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контактная лучевая терапия</kwd><kwd>брахитерапия</kwd><kwd>прямая дозиметрия</kwd><kwd>дозиметрия in vivo</kwd><kwd>снижение частоты лучевых осложнений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contact radiation therapy</kwd><kwd>brachytherapy</kwd><kwd>direct dosimetry</kwd><kwd>dosimetry in vivo</kwd><kwd>reduction of radiation complications rate</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">Солодкий В.А., Титова В.А.
