FIELD: medicine.
SUBSTANCE: invention relates to medical combined systems and methods of visualisation. A CT system forms structural data of the first field of visualisation, which are reconstructed by a reconstructing processor of the CT-system to form a visual CT-image. A system of radionuclide visualisation obtains functional data from the second field of vision, which is smaller than the first field of vision. The first reconstructing processor of a PET-system reconstructs the functional data into a visual PET-image. A processor of fusion combines the visual PET-image with a map, separated from the visual CT-image, to form a visual image with an extended field of vision. A unit of correcting the excess of radioactivity and a unit of correction the backscatter obtain data of correction of the radioactivity excess and the data of correction of the backscatter from the visual image with the extended field of vision. The reconstructing processor forms a visual functional image, corrected for the radioactivity access and the backscatter basing on the data of the radioactivity excess correction, the data of the backscatter correction and the functional data.
EFFECT: application of the invention makes it possible to increase a signal to noise ratio.
