Abstract
The system is based on combined detector: scintillating plate + image inten sifier + CCD matrix. The sensitivity of the detector allows the detection o f single photon with energy higher than 69 keV. The hexagonal URA masks of ranks 6 and 9 are used for coded mask imaging; transparent elements of mask are cylindrical holes of diameter 1.3-2.2 mm). The imaging possibilities o f device are presented by images of point and circular objects of different diameters obtained in experiments. (C) 1999 Elsevier Science B.V. All righ ts reserved.
