Paper Abstract

The method for obtaining optimum exposure factors of tube voltage and mAs value (the product of the tube current and the exposure time) is illustrated. For this purpose, attenuation curves of the energy absorbed in emulsion layers and characteristic curves of film, in which the absorbed energy is used as the input instead of exposure, are derived. In addition, the knowledge of the minimum perceptible contrast and the optimum film density is required.
