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'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'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.
