Photographs showing the LabDCT implementation on a conventional tomography setup using a (a) CCD (effective width × height = 50.0 × 50.0 mm) and (b) flat panel (effective width × height = 184.9 × 233.7 mm). A pinhole is placed between the sample and the nano source, and its position is controlled by three motors. A 2 mm-thick sheet of lead, covering the footprint of the direct beam, is attached onto the detector for DCT acquisition. |
