A computer-aided system to estimate bone age based on Fourier analysis was assessed by reference to the original radiographs used to produce the Tanner-Whitehouse 2 (TW2) standards for the radius, ulna and short finger bones. The computer-aided system involved matching a template of each bone to the scanned image of the radiograph. The computer then generated a stage of bone maturity, individual and total bone scores and a value for bone age. The bone ages assessed by the computer-aided system were no different from the original TW2 reference values, indicating the applicability of the system. The system was used to assess the bone ages of tall Dutch girls, and the results obtained were compared with more traditional assessments made by an experienced rater. For the radiographs from the tall girls, there was good agreement for individual bones between this method and the traditional assessment by the rater, but less agreement for the total 13-bone score and bone age.
通过参考用于生成桡骨、尺骨和短指骨的坦纳-怀特豪斯2（TW2）标准的原始X光片，对基于傅里叶分析的计算机辅助骨龄估计系统进行了评估。该计算机辅助系统包括将每根骨头的模板与X光片的扫描图像进行匹配。然后计算机生成骨成熟阶段、个体和总骨得分以及骨龄值。计算机辅助系统评估的骨龄与原始TW2参考值没有差异，表明该系统具有适用性。该系统用于评估荷兰高个女孩的骨龄，并将所得结果与经验丰富的评估者进行的更传统评估进行比较。对于高个女孩的X光片，该方法与评估者的传统评估在个别骨头方面有很好的一致性，但在13根骨头的总分和骨龄方面一致性较差。
