This study introduces a novel method for detecting coronary artery skeletons in angiograms. The approach uses image derivatives and profile analysis to accurately identify artery structures from noisy data.

Area of Science:

  • Medical Imaging
  • Image Processing
  • Cardiovascular Science

Background:

  • Coronary angiograms are crucial for diagnosing heart conditions.
  • Detecting coronary artery skeletons is vital for quantitative analysis.
  • Existing methods may struggle with noise in digitized angiograms.

Purpose of the Study:

  • To propose a new algorithm for detecting coronary artery skeletons.
  • To address the challenge of noise in digitized coronary angiograms.
  • To enhance the accuracy of coronary artery visualization.

Main Methods:

  • Treating angiograms as noisy samples of continuous surfaces.
  • Applying Gaussian filtering to reduce image noise.
  • Utilizing first and second-order image derivatives to detect topographic features.
