It is very important which the special xray equipment and photosensitive materials merely are prepared but also their maximum ability are shown for mammography which is taken photography of breast tissue having a few absorbed difference and requires showing the detail of change to a morbid state.
Especia lly, the physical properties of film are influenced on developing conditions, namely, developing temperature, developing time and developer. In this study, the physical properties were investigated by using some developing conditions.
In the results, it has been confirmed, which the temperature dependencies on physical properties of films for mammography are different with developing time and developer.
Furthermore, it has been confirmed, which it is very important wh en the maximum ability of the films for mammography is required, the suitable developing temperature must be investigated by using the automatic processor of each institution, that is, by using the developing time and developer of each institution.
