Quantitative assessment of image quality using niobium filtration for cephalometric radiography

Division of Radiology and Imaging Sciences, School of Dentistry, University of Louisville, Kentucky.

The effect of added niobium filtration on image quality in cephalometric radiography was quantitatively evaluated using the Modulation Transfer Function (MTF). A conventional full-wave cephalometric X-ray generator (Quint Sectograph) and a constant potential, high frequency X-ray generator (Orthophos CD) were compared with respect to the effects on the MTF of the added filtration. There was a slight reduction in image quality with both machines when adding niobium filtration.
