Optimal dose balance between energy levels for material decomposition with dual-energy X-ray CT

Résumé

Dual-energy X-ray imaging is used to extract quantitative material information, e.g., electron density and effective atomic number Z, using the differencesof X-ray attenuation coefficients of materials at different energies. A detailed study of factors that could influence the precision of extracted data is of importance. The aim of this study was to determine the optimal dose balance between the low and the high voltage acquisitions for material decomposition with dual-energy X-ray CT.
