【摘要】：以中华05骨龄标准为依据,基于骨龄图像的DICOM格式,设计和实现了桡骨骨龄80级~84级的计算机评定软件系统。系统自动对手腕部数字X光图像进行了预处理,采用区域生长法与最大类间方差法结合的方式实现了桡骨的有效分割,选取了灰度特征、纹理特征以及融合度作为骨龄特征参数,设计k近邻分类器对骨龄特征数据进行等级分类,并且结合ITK、VTK和MFC设计了一款桡骨等级评定软件,实现了桡骨等级80至等级84的计算机评定。实验结果说明,该系统的平均准确率达到85.2%,具有可扩展性和易用性的特点,丰富了计算机评定骨龄系统的应用研究。
[Abstract]:The DICOM format based on bone age image is based on the Chinese standard of 05 bone age. A computer software system for evaluating radial bone age is designed and implemented. The digital X-ray image of the wrist is preprocessed. The effective segmentation of radius is realized by the combination of region growth method and maximum inter-class variance method. Grayscale feature, texture feature and fusion degree are selected as parameters of bone age feature. A k-nearest neighbor classifier was designed to classify the bone age feature data, and a radial grading software was designed with ITK VTK and MFC. The computer evaluation of radius grade from 80 to 84 has been realized. The experimental results show that the average accuracy of the system is 85.2, and the system has the characteristics of extensibility and ease of use. It enriches the application of computer system for bone age assessment.
