| Popis: | The "Tanner-Whitehouse 2" method is the most popular in evaluating skeletal maturation, but this method has some inherent weak points. We therefore developed the new system to automatically evaluate the skeletal maturation of Japanese children by means of a personal computer. The subjects of this study were 318 healthy Japanese boys and 199 girls ranging from 2 to 15 years of age. The bone age was calculated by multiple regression analysis with parameters for the epiphysis and metaphysis. Successful automatic evaluation was about 80-90% on each phalanx. There was a significant correlation between chronological age and the ratio of epiphyseal width to metaphyseal width. The system developed in this study was useful for evaluating the skeletal maturation. |
