  • Ultrasound Technology

Background:

  • Feature extraction is crucial for liver characterization using ultrasound.
  • Ultrasound image quality and classification results are often affected by machine settings and clinician adjustments.

Purpose of the Study:

  • To develop a robust liver feature extraction method for ultrasound images.
  • To mitigate the impact of varying machine settings on image analysis and classification.

Main Methods:

  • Utilized 2D phase congruency for feature extraction.
  • Applied the method to three classes of liver ultrasound images.
  • Ensured the method is invariant to changes in image intensity and contrast.

Main Results:
