Abstract
The most accepted numerical method for the assessment of BA is Tanner-Whitehouse (TW2). However, its disadvantage is that it is laborious and requires trained staff. A method based on computer analysis of bone shape as indicator of maturity has been developed. The representative patterns of each maturity stage of the TW2 atlas have been digitized by means of a graphic board. The computer calculates the gravity center of the figures and representes the vectorial radius from the center of gravity to the point of the bone perimeter for each digitized point on a coordinate axis. The degrees of each vector (0-360°) correspond to axis X and the length of each vector to axis Y. The unified extremes of the vectors result in a representative curve of the bone shape. The comparison of a problem curve with the catalogue of standard curves of TW2 atlas has demonstrated that this method is easier than the classic method. The automatic comparison of the curves and imaging by video VICOM system is possible. The method is also being applied for the tarsal BA of newborns.
