Abstract

Xeroradiography is an x-ray modality with image attributes distinctly different from film. These attributes result from the electrical nature of the process in contrast to the chemical nature of the film process. More specifically, they result from the in-herent relationship between the latent image and the electric field resulting from the latent image. The field acts upon the developer in such a way that image elements representing sharp structures and edges are enhanced and broad area elements are subdued. This aids in the visualization of such breast architectural features as the skin line, masses, vascular structure, and micro-calcifications. It also aids in the visualization of fine bone fractures, detecting foreign bodies in soft tissue and in the examination of casted extremities. In this paper some of the attributes of xeroradiography which provide diagnostic useful information, the origin of edge enhancement of xeroradiographic images, sensitometric methods and some approaches to the measurement of sensitivity will be described.
