Abstract: FIELD: medicine. 
     SUBSTANCE: group of inventions relates to medical equipment, specifically to means of producing X-ray images. X-ray detector structure comprises an X-ray detector unit and a rotation unit, wherein the X-ray detector unit comprises an X-ray detector having a plurality of X-ray detecting elements made in the form of a detector surface, rotation unit is configured to rotate the X-ray detector about an axis perpendicular to the surface of the detector at least at a point of intersection with the surface of the detector, after receiving the rotation signal with respect to the X-ray detector unit, wherein the turn signal is controlled depending on the configuration of the collimator of the X-ray source structure for delivering X-ray radiation to the X-ray detector unit with the possibility of storing at least parameters of the collimator configuration together with working parameters of the X-ray detector structure. X-ray imaging system comprises an X-ray source structure and an X-ray detector structure, wherein the X-ray radiation source structure comprises an X-ray source unit, a collimator unit and a control unit, wherein the X-ray source unit is configured to generate X-rays to the X-ray detector structure, collimator unit has a collimator hole having adjustable dimensions to adjust the shape of the X-ray beam passing through the collimator hole, the control unit is configured to detect the collimator configuration and output, in response to the turn signal, to the turn unit, and rotation unit rotates X-ray detector based on turn signal so that rotary position of X-ray detector corresponds to configuration of collimator, wherein the control unit is configured to store at least collimator configuration parameters together with working parameters of the X-ray detector structure, detecting spatial displacement between the X-ray source structure and the X-ray detector structure, and comprises a moving assembly for performing relative movement to bring the structure of the X-ray detector to an X-ray source with an X-ray source structure based on the detected spatial offset. Method of setting detector comprises steps of adjustment (S210) of configuration of collimator of X-ray source structure, detection of spatial displacement between structure of X-ray source and structure of X-ray detector, relative movement to bring the structure of the X-ray detector to setting with the X-ray source structure based on the detected spatial displacement, maintaining at least parameters of configuration of the collimator together with working parameters of the structure of the X-ray detector, detecting (S220) the adjusted configuration of the collimator, outputting (S230) of the rotation signal to the rotation unit, wherein the turn signal is based on the detected adjusted configuration of the collimator, and rotation (S240) of the X-ray detector in accordance with the rotation signal. Machine-readable medium is designed to control the apparatus. 
     EFFECT: use of inventions improves clinical workflow.
