Basic Limits in Real-Time Industrial Radiographic Systems

Source

Industrial applications of radiography presently demand improvements in resolution when radiographic images are viewed on a real-time basis. Unlike medical applications (radiology), the dosage of incoming X-rays or gamma-rays does not impose serious restrictions in industrial applications. In addition, many advances in the area of computer-assisted intensification of image signals allow us to reexamine the present techniques of radiography from a fresh viewpoint. As a consequence, we may be able to make a major advance in the improvement of resolution in real-time radiography. In this paper, we discuss (1) collimation of primary radiation, including apparent size of sources, (2) monochromatic radiography to obtain true signals, (3) resolution improvement by a magnification of X-ray images before the radiation reaches the detecting (or viewing) system and, briefly, (4) intensification of signals when crystal collimation is used.
