Basic Imaging Properties of Radiographic Systems and Their Measurement

  • Chapter
Progress in Medical Radiation Physics

Abstract

The physical image quality of radiographs is known to be affected by at least three fundamental factors, namely, contrast, resolution (or sharpness), and noise (or radiographic mottle).(1,2) The contrast of a radiograph, commonly referred to as radiographic contrast, is related to the film contrast (or gradient), radiation contrast, and primary (or scatter) fraction. The gradient is usually derived from the characteristic curve (or H and D curve) of the screen-film system on which the radiographic image is recorded. The H and D curve is a basic imaging characteristic in radiographic systems and has been measured by a technique called sensitometry.
