IMPROVED GAMMA RADIATION IMAGING APPARATUS FOR EXACT LOCATION OF RADIATION SOURCES

摘要

FIELD: physics.;SUBSTANCE: gamma radiation imaging apparatus, having a gamma camera (10) for capturing an image of the observed scene (17) in gamma-rays resulting from the gamma image, having a front side (11) an axis of view (x1'), and an auxiliary camera (15) for capturing an image of the observed scene (17) in visible light, wherein the auxiliary camera (15) is placed in front of the front side (11) of the gamma camera (10), which is a collimating pinhole gamma camera, wherein the auxiliary camera (15) has an optical axis (x2') which substantially coincides with the axis of view (x1') of the gamma camera (10), such that the image in the visible light and the gamma image are captured substantially simultaneously with the same direction of view, owing to which the location of radiation sources, lying at distance from tens of centimetres to tens of metres from the gamma camera, is determined.;EFFECT: high quality of gamma radiation imaging.;14 cl, 4 dwg
