Niobium filters for dose reduction in pediatric radiology.


The performance of a niobium filter, with K-edge at 19 keV, and a copper filter have been studied concerning absorbed dose, image quality and tube loading. Absorbed doses were measured with TLD. To evaluate image quality a perspex phantom with image quality test objects was used. In comparison with a conventional filter made of copper no significant… (More)
