Abstract:
A nuclear medicine diagnostic apparatus for selecting, out of events involving detection of gamma rays by detectors, an event of paired gamma rays derived from a positron RI injected into a subject and simultaneously detected by the detectors and reconstructing sectional image data on the basis of count data relating to the selected event, comprising:an input device configured to designate a desired incidence direction; an incidence direction calculating circuit configured to calculate incidence directions of the gamma rays relating to the selected event on the basis of incidence positions of the gamma rays relating to the selected event; a planar image generating circuit configured to generate planar image data on the basis of count data relating to an event whose calculated incidence direction is coincident or near-coincident with the designated incidence direction; and a displaying unit configured to display a planar image on the basis of the planar image data.
