PROBLEM TO BE SOLVED: To clearly display a target organ by collecting images where the image of an adjacent frame or the image of frames with intervals exceeding the image corresponding to a measurement site are subtracted. SOLUTION: A scintillation camera 1 detects radiation being released from a specimen, performs A/D conversion 2, and converts a detection value inputted from the camera 1 into the image of a digital signal, and then outputs it to a collection means 3. The collection means 3 stores an image being outputted from the A/D converter 2 for each frame. A subtraction means 4 calculates the image difference between Nth frame and (N+1)th frame. A collection means 5 stores the output of the subtraction means 4 for each frame. An external storage means 6 stores information regarding a specimen along with an image being stored by the collection means 3 and 5. A display control device 7 converts a digital signal such as an image being stored in the collection means 3 and 5 into a video signal. |
