Abstract

The effect of development temperature on image characteristics was investigated for several medical x-ray films. Speed, fog, and granularity increased as temperature was increased from 85 to 110°F. The effect of increasing temperature on fog was different for each film. Contrast increased with increasing temperature until fog reached levels that caused the contrast to decrease. Greater quantum mottle was observed at higher temperatures because of increased speed and contrast. The quantum mottle produced when a given radiographic screen is used can be expressed as a function of film speed and contrast, irrespective of whether the film type or the development temperature has been changed.
