<p>PROBLEM TO BE SOLVED: To prevent new grid stripe information from being generated by removing processing of grid stripes by preventing the execution of removing processing concerning the area of radiograph, where the grid stripe information is not originally superimposed, when removing the grid stripe information superimposed on the radiograph. SOLUTION: In the radiograph processor for processing the radiograph provided by radiography using a grid for removing the scatter rays of radiation to an object, this device is equipped with a mask image generating part 17 for generating a mask image corresponding to the signal level of radiograph information, an image processing part 16 for masking the grid stripe information by using the mask image generated by the mask image generating part 17 and an arithmetic part 15 for subtracting the grid stripe information masked by the image processing part 16 from the radiograph information.</p> |
