DIGITAL RADIOGRAPHY IN THE ANALYSIS OF PAINTINGS: A NEW AND PROMISING TECHNIQUE
A. Everette James, S. Julian Gibbs, Malcolm Sloan, Ronald R. Price, & Jon J. Erickson
ABSTRACT—Recent advances in computer processing of images and the development of electronic x-ray detectors have made possible the development of digital radiographic techniques, which offer great potential for the analysis of paintings. The ability to distinguish very small differences in x-ray attenuation characteristics provides the possibility of quantitative analysis of pigment structures. The very sophisticated image processing techniques that have been developed for the space industry and medicine also may be applied to the analysis of paintings through the use of the digital radiographic images. In this communication, digital fluoroscopy, scanned projection radiography, and scanned point-source methods will be described. The virtues and limitations of each are noted. An initial experience with two of these methods will be the major subject of this communication.
1. Digital Fluoroscopy
2. Scanned Projection Radiography
3. Scanned Point Source System
