2. Current Status

Current Work

• Detection pulmonary trunk and arteries
  • EM classification -> done
• 3D blood vessel reconstruction
  • Thinning or skeletonization -> partially done
• Boundary detection
  • Intensity, 1st and 2nd derivative -> done
  • Zero-crossing voxels -> done
• Pulmonary artery tracking & quantification
  • Vessel tracking -> working
  • Radius and volume at each section -> partially done
• Visualization
  • Extracting PE area in 3DsSpace of f, df, and d²f -> done
  • A voxel is divided into 10 x 10 x 10 sub-voxels -> done

Future Work

• Pulmonary artery tracking & quantification
  • Vessel tracking -> working
  • Radius and volume at each section -> partially done
  • Performance increase
  • Topology preserving 3D thinning
  • Boundary detection
  • Extracting high resolution interesting area
