Summary:PROBLEM TO BE SOLVED: To provide a SPECT device which offers enhanced throughput of data collection.SOLUTION: A gamma camera 19 detects gamma rays. A rotation frame 11 supports the gamma camera 19 in a rotatable manner around a rotation axis Z. A driving unit 15 drives the rotation frame 11 in order to rotate the gamma camera 19 around the rotation axis Z. A data collection unit 21 collects projection data for each given projection angle on the basis of output from the gamma camera 19. A determination unit 25 determines whether there is abnormality in data collection for each given projection angle according to a degree of change in count rates for change of projection angle. A warning unit 29 immediately issues a warning when the determination unit 25 determines that there is abnormality in data collection.
