FIELD: medicine. ^ SUBSTANCE: group of inventions relates to field of medicine. Method is realised by system of computer tomography. System contains anode, surrounding examined area, source of electronic ray (cathode), detector matrix for detection of X-rays, adder for combining signals corresponding to X-rays, and reconstruction device for formation of three-dimensional image data. Method consists in rotation of electronic ray on anode during multitude of selection intervals. During each selection interval electronic ray is modulated for formation of multiple successive focus spots. Focus spots in specified selection interval include subset of focus spots from previous selection interval. Detector matrix performs selection of X-ray projections, irradiated by each of multiple focus spots, for each selection interval. Reconstruction device reconstructs X-ray projections for creation of three-dimensional image data. ^ EFFECT: application of claimed group of inventions will make it possible to increase resolution and improve image quality. ^ 32 cl, 13 dwg |
