FIELD: visualization of gamma-radiation, in particular, in medicine for visualization of radiations of isotopic indicator injected to patient. SUBSTANCE: image is formed by simultaneous reception of separate components of exposure plan. Selective blocking of gamma-radiation is accomplished by a blocking object. Two-dimensional image of gamma-radiation is formed by comparing the signals from separate components of the exposure plan with blocking device and without it. The object blocking the gamma-radiation is located for movement in the field of vision of the detector, which provides for alternate blocking of gamma-radiation from various regions of the exposure plan. The detector has a layer of scintillator linked with a photoelectric detector. EFFECT: provision of formation of two-dimensional image of exposure plan without any displacement of detector. 22 cl, 6 dwg
