In September 2008, hardcopy printing (film diagnosis) was replaced by softcopy reading (monitor diagnosis) at our facility. The softcopy reading enabled to lower radiography conditions in the child hip joint and to reduce more child exposure dose than we previously examined. In this study, the reduction of exposure dose in the present softcopy reading of the child hip joint was discussed using the same method as our previous report on hardcopy printing. This study indicates that the present softcopy reading enables to reduce exposure dose to approximately 44% of dose in the conventional hardcopy printing and to about 10% of dose in a guideline for medical exposure of Japan Association of Radiological Technologist (JART).
