Area of Science:

  • Biomedical Engineering
  • Radiology
  • Medical Imaging Analysis

Background:

  • Early detection of osteoarthritis in human knee joints requires noninvasive, inexpensive, and scalable methods.
  • Fractal analysis of trabecular bone (TB) texture in 2D X-ray images is a promising approach.
  • Existing methods face challenges in accurately characterizing bone texture roughness and anisotropy.

Purpose of the Study:

  • To evaluate the accuracy of a modified Hurst orientation transform (HOT) method for analyzing trabecular bone texture.
  • To investigate the effects of image noise, blur, exposure, magnification, and projection angle on HOT method performance.
  • To assess the HOT method's capability in measuring bone texture roughness and anisotropy.

Main Methods:

  • Utilized a modified Hurst orientation transform (HOT) method, which calculates 2D fractal dimension in all directions and measures anisotropy.

  • Employed computer-generated fractal surface images and actual X-ray images of human tibia heads for analysis.
  • Investigated the impact of various image quality parameters (noise, blur, exposure, magnification, projection angle) on the HOT method.

    • Main Results:

    • The HOT method demonstrated effectiveness in characterizing both roughness and anisotropy (isotropy) of trabecular bone texture.
    • The study assessed the performance of the HOT method under different image conditions, confirming its robustness.
    • Results indicate the HOT method's suitability for analyzing complex bone texture patterns.

    Conclusions:

    • The modified Hurst orientation transform (HOT) method is a reliable tool for quantifying trabecular bone texture characteristics.
    • This technique offers a viable noninvasive approach for early osteoarthritis detection through X-ray image analysis.
    • The HOT method's ability to measure anisotropy and roughness makes it valuable for understanding bone structural changes.
