PURPOSE:To improve display accuracy of a time axis of diagnostic image data and obtain various kinds of parameters by a method wherein when the various kinds of parameters necessary for diagnosis are to be obtained from dynamic R1 diagnostic image data of a sliced plane of a specimen, frame time calculation is performed as time containing both a preparatory period and a constant speed period. CONSTITUTION:A specimen 10 with R1 injected into is mounted on a bed 11, radioactive rays irradiated from the specimen 10 are detected, and its incident position signals X,Y and a brightness signal UNB are output from a detector 12. A normally and reversely rotating mechanism is provided in a mount 13 with the detector 12 connected to a support arm 14 so that this detector 12 can rotate normally and reversely rotate around the specimen 10. The output signals X,Y from the detector 12 and the UNB are A/D-converted 15 to be supplied to an acquisition controller 16 and added to memory data at corresponding memory positions in an acquired memory device 17 one by one. Then a detector rotation controller 18 controls the normally and reversely rotating mechanism stored in the mount 13.
