title: [Design and appliation of a kind of bone age automatic analysis and assessment device].
abstract: OBJECTIVE
  The 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 artificial 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, especially in the poor medical conditions in rural and remote areas.
