内容記述 | A characteristic curve is the graph that represents the relation of light quantity irradiated to a film. Determination of the characteristic curve is essential for a quantitative evaluation of radiography as is X-ray film radiographic imaging process. Plotting the density measured against the log of exposure given makes a typical X-ray film characteristic curve. The shape of the curve represents the contrast response of the X-ray film to a wide range of exposures. When it is not practical to generate the entire curve through a variation of a single exposure parameter, bootstrap methods can be used. By using a screen with a film, X-rays that pass through cultural properties are converted into light, thus permitting the film to be efficiently exposed to the light. Through the use of an intensifying screen, the quantity of X-rays is reduced. In this study the characteristic curves of a film with an intensifying screen were measured. As a result, fine density was obtained for the screen in irradiation time of 5 sec. The authors conclude that a screen provides a wide range of characteristics in a short time. Usually, only films have so far been used for radiography, but when a screen is used, it not only shortens time drastically with precision but also produces radiographs of a higher contrast. |
