ABSTRACT:
A method and apparatus for correcting the density of an image in radiography comprising an X-ray source, an image recording placed facing the source, and a support on which an object and surroundings to be X-rayed are intended to be positioned. The method comprises acquiring an image as a mask image; acquiring at least one image as an injected image after injecting a contrast agent into the object to be imaged; and determining corrected images of the mask image and of the injected image from acquisition parameters of the apparatus, from a composition of the imaged object and surroundings and from a composition of the injected contrast agent.
