A Film Copying Technique for Improving Radiographic Contrast
By copying radiographs on high gamma photographic film, a significant increase in overall system gamma can be obtained. For a given material of uniform density, a charge in thickness will result in a change in x-ray transmission which in turn produces a change in the optical density of a radiograph. This change in density can be intensified by factors as high as 6 times by film copying techniques. A number of applications, in which this intensification has proved useful, are described.
