Claim 5:
6. The method according to claim 1, characterized in that the determination of a delineation of the object in the section plane comprises an iterative curve fitting algorithm comprising:
the consideration of an a priori delineation of the object in the section plane as a calculated delineation of first iteration rank;
then iteratively,
the calculation, from the calculated delineation of a given iteration rank of the object in the section plane, of a number (NP) at least equal to three of simulated one-dimensional radiographic images (SSpk) of the region to be inspected, calculated in the section plane along the at least three different directions of projection (Dijk) which are used for the acquisition of the one-dimensional processing radiographic images (Spk) in the section plane,
the comparison of the simulated one-dimensional radiographic images (SSpk) with the one-dimensional processing radiographic images (Spk),
depending on the comparison, the modification of the calculated delineation into a calculated delineation of higher iteration rank, until the comparison of the simulated one-dimensional radiographic images (SSpk) with the one-dimensional processing radiographic images (Spk) reaches a predefined optimization criterion.
