摘要
A correlative evaluation of a sample using an x-ray computed tomography (CT) x-ray fluorescence (XRF) system and the method for analyzing a sample using x-ray CT and XRF is disclosed. The CT/XRF system includes an x-ray CT subsystem for acquisition of volume information and a confocal XRF subsystem for acquisition of elemental composition information. The CT/XRF system also includes a controller for managing the acquisitions by the x-ray CT subsystem and confocal XRF subsystem. Combining sub-micrometer spatial resolution 3-D imaging with elemental composition analysis in 3-D with ppm level sensitivity is important to elemental identification of precious metal grains in crushed and ground ores and floatation tailings in the mining industry.
