Chest is a wide dynamic range object composed complex and colorful organs. Therefore, in radiograph of the chest, if is difficult to describe the lung and mediastinum at the proper density on one sheet of film. We have divided it into three cases: film density, tube voltage region and the scatter medium, and introduced NEQ (u) , detectability, spectral SNR as an overall image quality evaluation, and studied application for chest radiography. We obtained the results in which the application of the speed compensating screen is superior to that of density compensating filter or wide latitude film. We realized the situation of directions and energy on scatter X-ray by the Monte-Carlo simulation. In addition, the applicatability of a high density grid was proved using chest radiography.
