Název v původním jazyce

Material decomposition utilizing dual energy computed tomography

Popis výsledku v původním jazyce

Generally, inspection of the carbon fibre reinforced composites with metal components is embraced due to significantly different attenuation coefficients of a metal and CFRP components. At least two snapshots have to be taken with different X ray spectrafor each CT projection to be able separate material components and/or to reduce so called metal artifacts. Related so called dual energy CT (DECT) method can be generally based on two principles: Utilizing two different X ray tube spectra with significantly different X-ray tube potentials and X-ray beam filters, not special requirementsfor X-ray detector; Splitting of the X-ray spectra into two (or more) bands utilizing energy thresholds which are set on the detector side (it supposes that detector hasthis ability as WidePix has). X-ray tube spectra can be shaped by the tube voltage and/or by X-ray beam filtering.
