The CT/XRF system (10) includes an x-ray CT subsystem (100) for acquisition of volume information and a confocal XRF subsystem (102) for characterization of elemental composition information. Geometrical calibration is carried out between the XRF subsystem (102) and the X-ray CT subsystem (100) such that a region of interest defined during X-ray CT acquisition can be retrieved by the XRF subsystem (102) for a subsequent XRF acquisition. The system (10) combines the sub-micrometer spatial resolution 3-D imaging capability of x-ray CT with the elemental composition analysis of confocal XRF to provide 3-D elemental composition analysis of a sample (104) with ppm level sensitivity. This is applicable to many scientific research and industrial applications, a prime example of which is the elemental identification of precious metal grains in crushed and ground ores and floatation tailings in the mining industry."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Combined confocal X-ray fluorescence and X-ray computerised tomographic system and method","description":"A correlative evaluation of a sample (104) using a combined x-ray computed tomography (CT) and x-ray fluorescence (XRF) system and the method for analyzing a sample (104) using x-ray CT and XRF is dis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739729","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
