  • Patent number: 9841388
    Abstract: An X-ray tomography device for providing a 3D image of a sample comprising a X-ray source, a cell, a photon detector and a processing unit. The processing unit computes the 3D tomography image on the basis of the acquired images corresponding to a plurality of cell angles. The cell is positioned so as the photon detector senses mainly photons coming from the sample inside the cell, and the photon detector is overexposed to cancel pixels corresponding to photons not coming from the sample.
