摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to visualisation systems in computed tomography. System includes X-ray source which rotates around examined area and moves along longitudinal axis. X-ray source remains in the first position on longitudinal axis during rotation around examined area, accelerates to the rate of scanning and performs through scanning of the area of interest, in which, at least one hundred and eighty degrees plus angle of fan-beam of data is are achieved. In the second version of system implementation X-ray source simultaneously rotates around examined area and moves along longitudinal axis, when irradiation is emitted during scanning. Motion of X-ray source and emission of X-rays by it are coordinated and controlled by means of character of movement of human body, located within examined area. In the third version of system implementation through scanning is controlled by periodic movement of scanned organ. Method of computed tomography lies in supporting X-ray source in static longitudinal position on z-axis with its rotation around examined area, movement of X-ray source in direction along z-axis with desired character of movement of human body, located within examined area and activation of X-ray source for irradiation.EFFECT: application of invention makes it possible to perform through scanning controlled by periodic movement of scanned organ.34 cl, 7 dwgИзобретение относится к медицинской технике, а именно к системам визуализации в компьютерной томографии. Система включает в себя рентгеновский источник, который вращается вокруг исследуемой области и продвигается вдоль продольной оси. Рентгеновский источник остается в первом положении на продольной оси в течение вращения вокруг исследуемой области, ускоряется до скорости сканирования и выполняет сквозное сканирование интересующей области, в которой достигается, по меньшей мере, сто восемьдесят градусов плюс угол веерного пучка данных.
