System and method for processing at least one polluting region of a digital image of an object exposed to x-rays

A method, implemented using a computer system, for processing at least one part, called polluting region, of a digital image of an object, the image being produced from an X-ray apparatus by exposing the object to X-rays, said image being stored in a data memory and comprising:

• points with each of which there is associated a numerical intensity value, called initial intensity I0, which corresponds to the number of photons that have struck a corresponding point of the object, and
• at least one item of metadata,
• wherein said at least one item of metadata comprises at least one of the following items of metadata:
• one or more physical parameters of the object, such as the thickness of the object,
• one or more parameters relating to the power or the energy of the X-rays with which the image was acquired, such as the voltage and electric current values used to produce the X-rays;
• said method comprising:
• identifying at least one group of points in the image corresponding to a polluting region on the basis of the initial intensity values I0 of the points in the image and of said at least one item of metadata;
• generating a new image comprising a step of replacing the initial intensity values I0 of at least some of the points of said at least one polluting region with new intensity values.
