Dual-energy projection radiography using condenser x-ray generator and digital radiography apparatus.
The authors describe a system for dual-energy projection radiography using a modified condenser-type x-ray generator and a digital radiography unit. High- and low-energy images are obtained within a practical exposure interval. This method provides better visualization of soft tissues that are otherwise obscured by skeletal structures and also allows better visualization of bone and calcifications (e.g., calcified nodules in the lung) without interference by overlying soft tissue.
