PURPOSE:To eliminate the displacement of the seam of a composite image due to nonparallelism between the moving direction of a bed and a detector by detecting the displacement of the seam of the composite image from scanning data on a phantom and adding this as a correcting value to scanning data on a body to be inspected. CONSTITUTION:The phantom is placed at the position of the object body 1 and scanned by the detector which incorporates a scintillation camera and the composite image is displayed on a composite image display device 13. If the seam of the composite image is displaced, the quantity of the displacement is set as the correcting value in a coordinate correcting device 20. Then, the object body 11 is scanned by the detector 1, and digital signals x', y', and z' are extracted through a position calculating part 12 and an A/D converter 16 and stored in an image memory and also displayed on a display device 13 after the correcting value set in the correcting device 20 is added. Consequently, even when the moving directions of the detector 1 and bed 3 are not parallel to each other, the composite image whose seam is not displaced is obtained.
