Claims (3)

A digital radiography device having a segmented imaging function that displays a fluoroscopic image of a subject on a display means, acquires a plurality of narrow-area radiographic images smaller than the displayed fluoroscopic image, and synthesizes the acquired narrow-area radiographic images to obtain a single image, the digital radiography device comprising: means for setting the narrow area at a desired position within the fluoroscopic image displayed by the display means; and control means for causing the display means to display an image frame of the size of the narrow area for the fluoroscopic image set by this setting means . A digital radiography device having a segmented radiography function for obtaining a plurality of segmented radiographs by referring to a fluoroscopic image of a subject displayed on a display means and synthesizing the obtained plurality of segmented radiographs to obtain a single image, comprising: means for setting a pixel size of the obtained segmented radiographs; and control means for displaying an image frame of a size corresponding to the pixel size of the segmented radiographs set by the setting means at a predetermined position within the fluoroscopic image displayed on the display means. 3. The digital radiography apparatus according to claim 1, wherein the fluoroscopic image is obtained by inserting a segmented mask having an X-ray irradiation field larger than the X-ray irradiation field of the acquired photographic image into the X-ray irradiation field of the fluoroscopic image.
