摘　　要：目的设计一种骨龄片分析处理的装置,可计算出患者预期身高和鉴定其生长发育水平。方法选取本院100例6-13岁儿童的DR骨龄片,利用半拉格朗日算法对骨龄片的目标兴趣区(ROI)进行图像分析,对比2名小儿内分泌专家(A、B)采用TW3法人工判读骨龄(两种方法均检测2次),并报告结果。结果骨龄评价的过程中,预测骨龄的误差缩小到0.12岁。结论装置可快速计算出患者预期身高和鉴定其生长发育水平,提高了骨龄评测速度和准确度,特别是在医疗条件较差的农村和偏远地区也可以进行。ObjectiveThe device of a bone age film of analysis and process was designed, can calculate the expected patient＆#39;s height and identify growth level and development.Methods Select the DR bone age of 100 children of 6-13 years old, used semi Lagrange algorithm of target region of interest on bone age piece （ROI） for image analysis, compared with 2 pediatric endocrinologists （A, B） who used TW3 artifi cial to judge bone age （two methods were detected 2 times）, and report the results. Results Bone age assessment process, forecast error of bone age reduced to 0.12 years.Conclusions This device can quickly calculate the expected patient＆#39;s height and identify his growth level, improve the speed and accuracy of bone age assessment, especialy in the poor medical conditions in rural and remote areas.
