PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of accurately specifying an analysis range to analyze a bone of analyte through subtraction imaging.SOLUTION: An apparatus according to the present invention allows switching between a subtraction image s and an X-ray image PL relative to an image displayed by a display part 29 to specify a portion for which analysis is executed by a bone analysis part 15. If two bones are connected into one on the subtraction image s, the x-ray image PL is effective to visually recognize their boundary because a close look of an unprocessed analyte image appearing in the X-ray image PL enables accurate perception of the bone shape. The present invention allows accurate recognition of the position of a bone boundary by property using the subtraction image s and the x-ray image PL depending on the situation.SELECTED DRAWING: Figure 1 |
