This study introduces computer-assisted analysis of hand radiographs for skeletal maturity assessment. Different image processing techniques are used for early development and epiphyseal fusion stages, with varying region sensitivities.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Radiology

Background:

  • Assessing skeletal maturity from hand radiographs is crucial for growth prediction.
  • Traditional methods can be subjective and time-consuming.
  • Automated analysis offers potential for improved accuracy and efficiency.

Purpose of the Study:

  • To develop and evaluate a computer-assisted system for skeletal maturity assessment using hand radiographs.
  • To investigate the effectiveness of different image processing techniques at various developmental stages.
  • To design a user interface for analysis and comparison with visual interpretation.

Main Methods:

  • Image analysis based on features from six regions of interest.
  • Feature extraction using Lee filtering, random Gibbs fields, and mathematical morphology for early stages.

  • Wavelet decomposition methods applied during epiphyseal fusion.
  • Development of a graphical user interface (GUI) for testing and visualization.

    • Main Results:

    • Identified varying sensitivities of different regions and features to skeletal development stages.
    • Distal features are more reliable indicators in early development.
    • Middle features become more sensitive during epiphyseal fusion due to a larger dynamic range.

    Conclusions:

    • Computer-assisted analysis of hand radiographs can effectively assess skeletal maturity.
    • Specific image processing methods and regions of interest are optimal for different developmental stages.
    • The developed GUI serves as a valuable tool for analysis, teaching, and future classification.
