PROBLEM TO BE SOLVED: To generate useful materials for achieving low-dose radiographing.SOLUTION: A search processing unit 31 of a central server 13 searches, from a storage device 22S, radiographing information 15 wherein a designated radiographing region coincides of all radiographing information 15 of medical facilities 11 having the radiographing information 15 wherein a detection device ID designated from a client terminal 17 coincides. A sorting unit 32 sorts the radiographing information 15 in order of an old radiographing date in each medical facility 11, and classifies the medical facilities 11 into the medical facilities 11 (first group) in each of which a dose has changed after introducing an X-ray image detection device of the designated detection device ID compared to before the introduction and the medical facilities 11 (second group) in each of which a dose has not changed. A statistical data generation unit 33 generates a histogram having a range of radiation dose in a class of a horizontal axis and the number of the medical facilities in frequency of a vertical axis, in each of the first, second groups. |
