A radiation image is recorded on a plurality of photostimulable phosphor screens of a size that is smaller than the size of the elongate body. The screens are exposed to a radiation image of a grid of threads of attenuating material and a radiation image of the elongate body so that each of the screens stores part of the image of the body and superimposed thereon, part of the image of the grid. The screens are read out individually. Reconstruction of the image of the elongate body is performed on the basis of the reconstructed image of the grid.
