Paper Abstract

A logical consideration of the digital imaging process (6) is described using the characteristics of the film and screen of a radiograph and a non-linear compensation curve for each pixel between optical density value of 100% exposure radiograph and 25% exposure radiograph obtained experimentally and theoretically. A radiological image of less than 100% exposure can be generated using the point-by-point mapping to form a radiographic image which is similar to that of 100% exposure. The mathematic expression of the film to screen characteristics and conversion between the optical densities of the 100% exposed radiograph and that of 25% exposure are given. A possible potential application of the digital imaging process is discussed.
