PROBLEM TO BE SOLVED: To provide a method for detecting concerned elements in the digital radiographic image of an object collected by a collecting chain, by a detecting system. SOLUTION: This method is provided with a calibration phase for setting the operation of a detection system as a first phase. A calibration curve having several dimensions is decided by an image acquisition system 21 and the mathematical model of an object, and false-positive probability is expressed as a function constituted of the image acquisition system 21 and the group of parameters corresponding to the object. In the process of a use phase being a second phase, the value of the false-positive probability is decided for each pixel. Then, the pixels whose obtained probability values satisfy a predetermined reference are selected from among the obtained pixels of a digital radiographic image. |
