This study presents a 3D coronary arterial tree reconstruction method using biplane angiograms. It enables accurate 3D vascular measurements and flow analysis for computer-assisted quantitative angiography.

Area of Science:

  • Medical Imaging
  • Cardiovascular Science
  • Biomedical Engineering

Background:

  • Accurate three-dimensional (3D) reconstruction of the coronary arterial tree is crucial for diagnosing cardiovascular diseases.
  • Existing methods may lack precision in capturing complex vascular structures and functional parameters.

Purpose of the Study:

  • To develop and validate a novel method for reconstructing the 3D coronary arterial tree from biplane 2D angiographic images.
  • To enable accurate quantitative analysis of coronary vascular morphology, function, and stenosis.

Main Methods:

  • Utilizes geometrical mathematics of X-ray imaging and contrast material tracking.
  • Identifies corresponding points on orthogonal biplane angiographic views.
  • Reconstructs 3D spatial position, dimensions, and displays as a shaded surface model.
