摘要： When radiography is performed on a patient at a radiography apparatus, first, a past collected radiation dose for the patient and a past collected radiation dose for a region of the patient on which radiography will be performed are extracted from a database.Judgment is made as to whether the collected radiation doses are greater than or equal to respective set threshold values. If it is judged that at least one of the collected radiation doses is greater than or equal to the set threshold values, the radiography apparatus outputs an alert for a radiographer. If it is judged that the collected radiation doses are less than or equal to the set threshold values, radiography is started by the radiography apparatus.
