FIELD: medicine.SUBSTANCE: invention can be used for x-ray tomography. Invention consists in fact thatx-ray tomography apparatus for producing 3D tomographic image of sample contains x-ray source which emits beam of photons in direction of beam axis, x-ray source is source of close to monochromatic light source, and beam of photons has spatial angle of more than 0.1 degrees relative to beam axis; cell which can include porous sample, image of which is taken with possibility of location of cell inside photon beam and cell turn about its axis, which is substantially perpendicular to beam axis, as well as to provide flooding of said porous sample with at least one fluid medium; photon detector, receiving passing beam of photons, which is passed through cell, photon detector provides obtaining at least one image for each angle of multiple angles cell, wherein obtained images are taken for less than 10 minutes; and processing module configured to calculate tomography image based on said image corresponding to said multiple angles of cell.EFFECT: technical result is possibility of fast production of 3D tomographic images of fluid displacement in sample of porous medium.10 cl, 2 dwg |
