Была проведена сцинтиграфия органов грудной клетки пациента с периферическим плоскоклеточным раком верхней доли правого легкого на двухдетекторной гамма-камере GE Discovery NM/CT 670 DR (США) с использованием высокоразрешающих коллиматоров для энергии 140 КэВ и радиофармпрепарата (РФП) 99mТс-Технетрил (МИБИ, “Диамед”, Москва). Полученные данные подвергались компьютерной обработке с использованием специализированной системы Xeleris 4.0 фирмы “GE” (США). Создан ПК, который включает программу генерирования воксельного фантома («виртуальный пациент»), программу моделирования сбора «сырых» проекционных данных («виртуальный томограф») и программу реконструкции изображений на основе алгоритма OSEM (Ordered Subset Expectation Maximization). С целью валидации созданного ПК выполнено имитационное компьютерное моделирование клинического случая. Полуколичественный сравнительный анализ изображений основывался на оценке опухоль/ фон.</p></sec><sec><title>Результаты</title><p>Результаты. Наблюдается достаточно хорошая корреляция между клиническими «сырыми» данными, записанными с реального пациента, и проекционными данными, рассчитанными методом Монте-Карло с «виртуального пациента». Результаты сравнительного анализа показали, что на реконструированных изображениях оценка опухоль/фон занижена.</p></sec><sec><title>Заключение</title><p>Заключение. Вопрос о точности реконструкции опухолевых поражений при использовании стандартных алгоритмов реконструкции OSEM не изучен. Этот вопрос важен при ведении пациентов с опухолевыми поражениями легких и требует изучения и систематизации. Разработанный ПК будет использоваться в последующих исследованиях для изучения ошибок и артефактов на изображениях опухолевых поражений, а также разработки подходов для их преодоления.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to develop and validate a software package (SP) for computer simulation of the procedure for examining patients with lung cancer by SPECT/CT and assessing the accuracy of reconstruction of tumor lesions.</p><sec><title>Material and Methods</title><p>Material and Methods. Lung scintigraphy for a patient with peripheral squamous cell carcinoma of the upper lobe of the right lung was performed using a two-detector gamma camera GE Discovery NM/CT 670 DR (USA) with high-resolution collimators for an energy of 140 KeV and a radiopharmaceutical (RP) 99mTc-Technetril (MIBI, Diamed, Moscow). The data obtained were subjected to computer processing using a specialized Xeleris 4.0 system from GE (USA). The SP included a program for generating a voxel phantom (“virtual patient”), a program for modeling the “raw” data acquisition (“virtual tomograph”) and an image reconstruction based on the OSEM algorithm (Ordered Subset Expectation Maximization). In order to validate the created SP, computer simulation of the above clinical case was performed. The semi-quantitative comparative image analysis was based on a tumor/background score.</p></sec><sec><title>Results</title><p>Results. There was a good correlation between clinical “raw” data recorded from a real patient and projection data calculated by the Monte Carlo method from a “virtual patient”. The results of the comparative analysis showed that the tumor/background assessment was underestimated in the reconstructed images.</p></sec><sec><title>Conclusion</title><p>Conclusion. The problem of the accuracy of the tumor lesions reconstruction by using standard OSEM reconstruction algorithms has not been studied. This issue is important in the management of patients with tumor lesions of the lungs and requires study and systematization. The SP will be used in further studies to analyze errors and artifacts in images of tumor lesions, as well as to develop approaches to overcome them. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерное моделирование</kwd><kwd>математический фантом</kwd><kwd>воксельный фантом человека</kwd><kwd>итерационный алгоритм реконструкции</kwd><kwd>ОФЭКТ/КТ</kwd><kwd>рак легкого</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer simulation</kwd><kwd>mathematical phantom</kwd><kwd>voxel human phantom</kwd><kwd>iteration reconstruction algorithm</kwd><kwd>SPECT/CT</kwd><kwd>lung cancer</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">Amin M.B., Greene F.L., Edge S.B., Compton C.C., Gershenwald J.E., Brookland R.K., Meyer L., Gress D.M., Byrd D.R., Winchester D.P.
