Tone Reproduction in Medical Radiography

Paper presented at the 11th International Congress on Radiography, Rome, 1965.

Abstract

The concept of tone reproduction in visible-light photography can be extended, by analogy, to medical radiography. First a correspondence between the luminance values of the intensifying screen, or the image intensifier, and the absorptions by the different anatomic details is established by photographic photometry on an equivalent Plexiglas step wedge. The method is then employed for the determination of the optimum characteristic of the photographic system when examining the skull, the lungs, the stomach, or for urography
