Abstract
The use of information contained in the transmitted x-ray spectrum provides the capability for selective removal of substances of a particular mean atomic number in projection radiographs. Using a prototype system for line-scanned digital radiography, x-ray images were produced with two different x-ray spectra by modulating the kVp applied to the x-ray source and filtering the x-ray beam. Using a previously described Compton/photoelectric decomposition algorithm, subtraction images are made with bone or soft-tissue (water) shadows removed. Applications to chest, abdominal and skeletal imaging in-vivo are demonstrated.
