    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.

    摘要翻译： 当在放射线照相设备上对患者进行射线照相时，首先从数据库中提取对于患者的过去采集的辐射剂量以及将在其上进行射线照相术的患者的区域的过去采集的辐射剂量。 判断所收集的辐射剂量是否大于或等于相应设定的阈值。 如果判断所收集的辐射剂量中的至少一个大于或等于设定的阈值，则放射摄影装置输出针对放射技师的警报。 如果判定所收集的辐射剂量小于或等于设定的阈值，则由放射摄影装置开始射线照相。

    摘要： A first leakage current value output from each signal line is stored in a storage unit, with a charge corresponding to an emitted radiation being held in a radiographic image detector, when the radiation is uniformly emitted to the radiographic image detector. A second leakage current value is acquired which is output from each signal line, with a charge corresponding to the radiation dose being held in the radiographic image detector, when the radiation passing through an object is emitted to the radiographic image detector. When the first and second leakage current values are equal to each other for each line corresponding to each signal line, all pixels on the line are determined to belong to a background area (lines A and C). When the second leakage current value is smaller than the first leakage current value and larger than a predetermined value, it is determined that there are the object areas and the background areas on the line (lines B, D, and E), and the total number of pixels in the background area on the line is calculated from the ratio of the first leakage current value to the second leakage current value. In this way, the distribution of the object area and the background area in the image which is held in the radiographic image detector when the radiation passing through the object is emitted is estimated before the reading of the image from the radiographic image detector is completed.
