Материалы и методы исследования. Метод предполагает разложение температурного сигнала на спектральные составляющие, модификацию спектральных составляющих и обратное преобразование спектральных составляющих в сигнал, рассматриваемый как колебания кровотока. Модификация спектральных составляющих выполняется с учетом тепловых свойств кожи и предназначена для компенсации затухания и запаздывания спектральных составляющих температуры относительно составляющих кровотока. Результаты. Продемонстрированы карты колебаний кровотока в области кистей, полученные в результате обработки термограмм в процессе проведения окклюзионной пробы. Рассчитанные из термограмм значения колебаний кровотока подтверждены измерениями кровотока методом фотоплетизмографии. Выводы. Методика позволяет восстанавливать колебания кровотока в любой точке термограммы исследуемого объекта. К преимуществам визуализации колебаний кровотока тепловизионным методом можно отнести: независимость сигнала кровотока от внешних источников видимого излучения и угла съемки, сигнал может регистрироваться как на поверхности всего тела, так и на отдельных его участках. В перспективе описанная технология тепловизионной визуализации колебаний кровотока может применяться для мониторинга кожной микроциркуляции крови в конечностях при прогрессировании и лечении таких патологий, как синдром диабетической стопы, синдром Рейно, а также в случае ожогов, обморожений, травм или атеросклероза.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The aim of the study was description of the method of skin blood flow imaging via spectral processing of the dynamic thermograms of extremities. Materials and methods. The method realized by decomposition of the temperature signal into spectral components, modification of the spectral components and inverse transform of the spectral components into a new signal, which is considered as blood flow. Modification of spectral components was accomplished taking into account skin properties, and intended for the compensation of attenuation and time lag of temperature spectral components relative to blood flow components. Results. Blood flow maps of hands during arm cuff test have been demonstrated. Blood flow values calculated from the dynamic thermogram have been validated by photoplethysmography. The technique allows restoring of the blood flow oscillations at any point of the thermogram of the object. Benefits of thermal imaging of blood flow are the following: results are not depended from the ambient light, the method not critical to the camera angle, and blood flow maps can be registered both from the whole body and small areas. The method of blood flow imaging, in a long view, applicable for the monitoring of the skin microcirculation in progression and treatment of diabetic foot syndrome, Raynaud's syndrome, as well as burn, frostbite, mechanical injury, and atherosclerosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тепловидение</kwd><kwd>термография</kwd><kwd>фотоплетизмография</kwd><kwd>визуализация</kwd><kwd>колебания температуры</kwd><kwd>колебания кровотока</kwd><kwd>вейвлет-анализ</kwd><kwd>thermal imaging</kwd><kwd>thermography</kwd><kwd>photoplethysmography</kwd><kwd>imaging</kwd><kwd>temperature oscillations</kwd><kwd>blood flow oscillations</kwd><kwd>wavelet analysis</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">Сагайдачный А.
