Abstract:
1. A radiographic imaging apparatus for taking a radiographic image of a subject using a radiation detector, the apparatus comprising: information obtaining means for obtaining calibration information by carrying out calibration of the radiation detector; storage means for storing the calibration information of at least one radiation detector with associating the calibration information with the at least one radiation detector; image processing means for applying image processing to imaging data of the radiographic image of the subject detected by the radiation detector based on the calibration information; detecting means for detecting at least one of conditions including that power is applied to the radiation detector, that a predetermined time period has elapsed from the application of power, and that the radiation detector is connected; and control means for determining, when at least one of the conditions is detected by the detecting means, whether or not the calibration information of the currently used radiation detector is appropriate, and if a negative determination is made, controlling the information obtaining means to enable the calibration, wherein the control means determines, with respect to the currently used radiation detector, that the calibration is unnecessary in the case that: 1) an elapsed time is within a predetermined time period from a time and date when the last calibration was carried out and the power was turned off at least once, and 2) an accumulated number of times of imaging with the radiation detector is within a predetermined number of times.
