Scheme of the experimental set-up of the 7B2 beamline at the Pohang Light Source. (a) The size of the polychromatic beam emanating from the bending-magnet device (BM) was reduced to match the scintillator after passing through the slit (Sl). The X-rays irradiated the CPD on the rotation stage (RS) that was positioned 28 m from the X-ray source. The visual images on the surface of the CdWO4 scintillator (St) that was placed 23 cm from the object were reflected 90° by a gold-coated mirror (Mi) and magnified by a microscopic objective lens (×5; Ls). Finally, the images reached the charge-coupled device (CCD) camera. (b) The CPD was held vertically and 1000 projection images were obtained during its rotation through 180°.
