Method for the radiographic imaging of a three-dimensional internal structure which forms part of an object located within a field of view, the method comprising: a) receiving first image data generated in a three-dimensional reference frame of reference, representative of at least one two-dimensional radiographic image of the internal structure of the object, b) receiving second image data generated in the reference frame of reference, representative of a three-dimensional image of an outer boundary of the object, characterized in that it comprises the steps of: c) estimating from the second image data the coordinates in the reference frame of reference of first characteristic markers of the internal structure, and, optionally, the value of at least one characteristic parameter of the internal structure, d) calculating, in the reference frame of reference, the three-dimensional shape of a model representing said internal structure from a previously known generic model of said internal structure, this generic model including points corresponding to the first markers, the calculated model being obtained by deformation of the generic model such that said calculated model observes a shape that is closest possible to an isometry of the generic model while keeping the points of the deformed generic model coincident with the first markers, and optionally by applying to the calculated model the characteristic parameter(s) of the internal structure, e) selecting at least one second characteristic marker of the internal structure to be located on the radiographic image, and for each second marker: i) identifying a point belonging to the model calculated in step d) corresponding to the second marker, (ii) calculating the coordinates of a projection of this point onto the radiographic image, iii) determining using the first image data the coordinates of the second marker on the radiographic image by searching for same in a search zone located around the coordinates of the projection. a) receiving first image data generated in a three-dimensional reference frame of reference, representative of at least one two-dimensional radiographic image of the
