A radiographic imaging apparatus with which the rotation amount of acquired radiographs can be the same in comparative interpretation of these images. The radiographic imaging apparatus includes an imaging unit for emitting radiation from a radiation source to a subject and detecting radiation having passed through the subject with a radiation detector having sensors arrayed therein to acquire a radiographic image, an image processor for performing rotation processing on the radiographic image to produce an acquired radiograph and collateral information of the acquired radiograph, a storage unit for storing the acquired radiograph and the collateral information, and a monitor for displaying the acquired radiograph. The collateral information contains the direction in which the sensors are arrayed and a rotation angle used in the rotation processing and is correlated to the acquired radiograph.
