Однако значения количественных параметров изображения смещаются вверх, что может приводить к значимым различиям с количественной оценкой, полученной на аппарате предыдущего поколения. Для сопоставления количественных оценок, полученных на аппаратах разных поколений, требуется проведение процедур, направленных на достижение сопоставимости (гармонизацию) количественных параметров изображения, совместно с регулярным контролем качества выполнения исследования. Цель настоящей работы – сравнение разных методик гармонизации количественных параметров изображений на примере гармонизации 2 аппаратов: Biograph mCT 128 и Biograph Vision 600. На аппаратах было проведено сканирование фантома NEMA IEC Body, заполненного раствором 18F, в режиме списка в 2 положениях кровати с перекрытием в области сфер в течение 5 мин на 1 положение кровати. При анализе изображений для каждой сферы фантома определяли коэффициент восстановления, который использовали для гармонизации. Гармонизация Vision и mCT была проведена двумя методами: подбор гармонизированных параметров реконструкции и использование технологии EQ.PET. Считали, что допустимый интервал расхождений, полученных коэффициентов восстановления на аппарате Vision с аппаратом mCT: ±10%. Значения коэффициентов восстановления, полученные для реконструкции 4 итерации и 5 подмножеств, ToF+PSF, Гаусс 7 мм, матрица 220×220 полностью укладываются в 20% интервал. Полученные значения коэффициентов восстановления с применением EQ = 6 мм (оптимальное значение) укладываются в 20% интервал, за исключением очагов диаметром 10 и 13 мм. Оба рассматриваемых метода гармонизации позволяют приблизить значения количественной оценки, однако применение технологии EQ.PET ограничено для очагов малых размеров. При этом метод гармонизации, подразумевающий подбор гармонизированных параметров реконструкции, является наиболее широко применяемым, а технология EQ.PET позволяет гармонизировать количественную оценку без использования нескольких протоколов ре[<xref ref-type="bibr" rid="cit1">1</xref>]конструкции и потерь в визуализирующей способности.</p></abstract><trans-abstract xml:lang="en"><p>The usage of modern positron emission tomography scanners, in particular with digital detectors, allows obtaining images with better quality, increases the detection of small pathological lesions, reduces scanning time and the activity administered to the patient which leads to a decrease of patient dose as well. However, the values of the quantitative image parameters shift upward, which can lead to significant differences with the quantitative assessment obtained on the previous generation device. In order to compare quantitative assessments obtained on different generations of PET/CT, it is necessary to harmonise quantitative image parameters and perform regular quality control. The aim of current work is the comparison of different methods for harmonization of quantitative image parameters on the example of harmonisation of two PET/CT: Biograph mCT 128 and Biograph Vision 600. NEMA IEC Body phantom filled with 18F solution was scanned in Listmode in two bed positions with overlap in the sphere area during five minutes per bed position. Recovery coefficient used for harmonisation was measured for each sphere of the phantom. Harmonisation between Vision and mCT was performed using two methods: choosing of harmonised reconstruction parameters and EQ.PET technology. The acceptable divergence range between the recovery coefficients for Vision and for mCT is ±10% (20% range). The recovery coefficients measured for reconstruction: 4 iterations and 5 subsets, ToF+PSF, Gaussian 7 mm, matrix 220x220 completely fit within the 20% range. The recovery coefficients measured using EQ = 6 mm (optimal value) fit within the 20% range except the spheres with a diameter of 10 and 13 mm. Both harmonisation methods allow to approximate the quantitative assessment/ However, EQ.PET has limitations for the small lesions. Choosing harmonised reconstruction parameters is the mostwidely used harmonisation method; the EQ.PET allows to harmonise quantitative assessment without the use of multiple reconstruction protocols and losses in visualization ability</p></trans-abstract><kwd-group xml:lang="ru"><kwd>позитронная эмиссионная томография</kwd><kwd>Biograph mCT 128</kwd><kwd>Biograph Vision 600</kwd><kwd>гармонизация количественной оценки</kwd><kwd>параметры реконструкции</kwd><kwd>EQ.PET</kwd><kwd>фантом NEMA IEC  Body</kwd></kwd-group><kwd-group xml:lang="en"><kwd>positron emission tomography</kwd><kwd>Biograph mCT 128</kwd><kwd>Biograph Vision 600</kwd><kwd>harmonization of  quantitative assessment</kwd><kwd>reconstruction parameters</kwd><kwd>EQ.PET</kwd><kwd>NEMA IEC Body phantom</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках отраслевой программы  Роспотребнадзора «Разработка и научное обоснование  комплекса мер по обеспечению радиационной защиты в  ядерной медицине».</funding-statement><funding-statement xml:lang="en">The work was performed as a part of the program of Federal  Service for Surveillance on Consumer Rights Protection and  Human Wellbeing “Development and scientific justification  of a set of measures to ensure radiation protection in nuclear  medicine”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rijnsdorp S., Roef M.J., Arends A.J.
