PDF-Bone density scanning also called dualenergy xray absorptiometry DXA

An xray radiograph is a painless medical test that helps physicians diagnose and treat medical conditions Radiography involves exposing a part of the body to a DEXA is also effective in tracking the. Visible light for example can be diffracted by a grating that contains scribed lines spaced only a few thousand angstroms apart about the wavelength of visible light Xrays have wavelengths on the order of angstroms in the range of typical interatomi Maximum . energy of emitted x-ray beam depends on tube voltage . applied . across the x-ray tube;.
