Abstract

Digital radiography (DR) utilizes subtraction techniques to provide improved low-contrast detectability. A recently reported dual-potential imaging technique has demonstrated that it is possible to achieve selective tissue and bone visualization in resultant images. This paper describes some results of an ongoing project in dual-potential imaging. Three different types of digital radiographical equipment are used in this project: (1) a fan beam system, (2) an area beam system, and (3) conventional x-ray films plus an image processor. Step wedges and a Lucite® phantom with cavities for contrasting material were constructed for the experiment. Images of this phantom and of a lung-chest phantom using these three types of equipment are presented and compared.
