This study introduces an automated X-ray cephalometric analysis system. The new system simplifies analysis, offering a more convenient and precise tool for cephalometry.

Area of Science:

  • Medical Imaging
  • Computer-Aided Diagnosis
  • Orthodontics

Background:

  • Cephalometric analysis is crucial in orthodontics but often involves time-consuming manual steps.
  • Existing methods can be subjective and prone to errors.
  • There is a need for automated, reliable cephalometric analysis tools.

Purpose of the Study:

  • To develop an automated X-ray cephalometric analysis system.
  • To simplify cephalometric procedures.
  • To provide a convenient and reliable method for cephalometric analysis.

Main Methods:

  • The system was programmed using visual-c, incorporating graphics, image processing, and artificial intelligence.
  • Techniques include Median filtering, Histogram equalization, and Canny edge detection for pattern recognition.
