Schematic setups for (a) home-laboratory cone-beam attenuation-contrast CT and (b) synchrotron parallel-beam XRD-CT. (c) A sample coordinate system r′ = (x′, y′, z′)T defined such that the z′ axis is parallel to the laboratory frame y axis. The local preferred orientation for each sample voxel is described by û str(r′). (d) An illustration of a uniaxial scattering intensity distribution for a single sample voxel.
