PURPOSE:To quickly and accurately align plural radiographs without recording a marker or the like together with an object in order to align them by setting a corresponding point within the range of the object image of the radiograph and aligning the corresponding points of the plural radiographs. CONSTITUTION:The device is constituted of an object image range decision means 51 to which an image signal 50 is inputted and which obtains the range of the desired object image from the signal 50 and outputs the range of the object image, a corresponding point decision means 52 to which the information of the range of the object image is inputted and which decides the plural corresponding points, which are used for aligning and which are common to the plural radiographs, and an alignment means 53 aligning the plural radiographs by aligning the plural corresponding points. Then, the range of the object image is obtained based on the signal 50 showing the radiograph and the plural corresponding points being common to the plural radiographs are obtained from the range. By aligning the plural corresponding points, the plural radiographs are aligned. |
