FIELD: physics.SUBSTANCE: when obtaining images of an object, the principle of arrangement of objects, associated with measurement, which is carried out when photographing, is observed. The photograph obtained using X-rays simultaneously includes a certain number of reference points whose positions are known in a three-dimensional coordinate system. The method involves use of coordinates of the reference points in both the Cartesian coordinate system, associated with reconstruction of the three-dimensional image, and in a coordinate system associated with digital photographing, which is required to establish the relationship which enables to perform transformations between these two coordinate systems. The path and the position of each X-ray beam are determined using said relationship. Also, all three-dimensional elements associated with each of those X-ray beams passing through the object of interest are determined.EFFECT: high resolution and shorter duration of exposure to X-rays, as well as simple design of the device, low power consumption and less rigid conditions for facilities where the device is used.3 cl, 11 dwg |
