抄録

The physical properties of screen film systems for mammography were evaluated by measuring characteristic curves, Wiener spectra and modulation transfer functions at constant developing temperature (34°). Furthermore, the developing temperature dependencies of physical properties on films for mammography were evaluated by measuring characteristic curves and noise RMS in the developing temperature extent from 26° to 44°.<BR>The mutual comparison of each corporation was not carried out; therefore it was not concluded which is the best system and the best film. In the result, it has been confirmed, which is very consequencial, that a system should be selected by an examination; for example: screening or close examination, because a relationship of trade -off is between sensitivity and granularity and sharpness.<BR>Furthermore, as the films have the higher limit of developing temperature, it has been established, which is very important, that the developing temperature must be decided by an estimate of developing temperature dependency of physical properties on films for mammography, and at that time the automatic processor of each institution must be used because the physical properties of films depend upon developer and developing time.
