Abstract

Selective removal of substances of a particular mean atomic number in projection radiographs has been accomplished using an experimental system for line-scanned digital radiography. X-ray images were produced with two different X-ray spectra by modulating the kilovoltage applied to the X-ray source and the filtration between the source and the patient. A Compton/photoelectric decomposition algorithm provided subtraction images with bone or soft-tissue (water) shadows removed. Applications to chest, abdominal, and skeletal imaging in vivo are demonstrated.
