Abstract:
The paper deals with image quality of films using a medium format type film and fluorography. Contrast transmission function is achieved by special calcium tungstate screens. In practice, image quality equals that of full size films with universal screens. By increasing lens size it is possible to reduce the necessary x-ray dose without losing image quality.
