FIELD: physics.
SUBSTANCE: invention relates to computed tomographic scanner. Proposed device comprises: radiation source (2) and detector (6) to generate detection magnitudes depending on radiation conical beam (4). Unit (12) generates weights for combination of image voxels and detection magnitudes for weighing said detection magnitudes. Beam generator generates the radiation conical beam (4) so that for at least for a portion of magnitudes dispersion inversion of appropriate magnitude positively correlates with the mean values of weights of appropriate combinations of voxels. The latter correspond to appropriate magnitude of detection.
EFFECT: higher quality of reconstructed images.
