A schematic overview of the LabDCT technique with the setup geometry defined in a laboratory right-handed coordinate system ([\hat x], [\hat y], [\hat z]). The incoming beam, emitted from a point source (S), travels through an aperture and illuminates the sample, and the detector records the transmitted signals. For a diffraction event occurring at the sample position M, the incoming wavevector Kin and scattered wavevector Kout together determine the scattering vector Glab. Position Q indicates the intersection point of the diffracted beam with an ideal detector and [\overrightarrow {PQ}] stands for the projection of Glab on the detector. P1, P2 and P3 indicate the centre, the centre of the top edge and the centre of right edge of the detector, respectively. Note that the dimensions are not to scale.
