概要

The amount of information obtained from the non-visible information source was calculated by means of the entropy method. This method was applied to the radiographic imaging system of a clinical chest examination. The relative efficiency of the transmission transmitted from anatomically fixed positions of the human body to the photographic densities on the chest radiographs through the system was as follows. They were 43.8% for the male's chest, 41.6% for the female's chest and 51.9% for the chest phantom at one facility, and 50.4% for the male's chest at another facility. Accordingly, it is considered and made sure that the entropy method can be used as one of the calculation methods for information quantities derived from the non-visible information source.
