FIELD: medicine.
SUBSTANCE: claimed invention relates to X-ray systems for obtaining images with high resolution. System of X-ray scanner contains matrix of spatially distributed successively commutated X-ray sources with specified frequency of commutation. Each X-ray source contains anode with flat surface, inclined at acute angle with respect to plane, perpendicular to direction of inlet electronic beam, in-built drive unit and unit of drive control for control of size, direction, rate and/or acceleration of translational and/or rotary movement of anode. In the second version of implementation system of X-ray scanner additionally contains deviating means for generation of electric and/or magnetic field, deviating electronic beam in direction, opposite to direction of translational movement of rotating anode, and unit of deviation control for adjustment of electric and/or magnetic field intensity in such a way as to compensate deviations of focus spot position, which result from translational displacement of rotating anode with respect to immobile installation plate. In the third version of system implementation unit of drive control is made with possibility of controlling size, direction, rate and/or acceleration of translational movement of respective anode, performed by, at least, one in-built drive unit depending on deviation of anode temperature in position of focus spot from nominal operating temperature.
EFFECT: application of invention makes it possible to prevent anode fault resulting from overheating.
