Objective:

To enhance the interpretation of OCT volumetric data by integrating ex vivo middle ear models with in vivo OCT models, thereby improving diagnostic capabilities.

Key Findings:
  • C2P-Net successfully registers complete point cloud templates to partial point clouds of the middle ear, demonstrating robustness.
  • The Blender3D generation pipeline effectively simulates synthetic shape variants and noisy point clouds that closely resemble in vivo data.
Interpretation:

The proposed methods significantly enhance the accuracy of middle ear diagnostics by improving the interpretation quality of OCT data.

Limitations:
  • Absence of real OCT data with ground truth for effective training and validation.
  • Difficulty in establishing one-to-one correspondences due to noise and incompleteness in OCT models, which may hinder accuracy.
Conclusion:

The integration of ex vivo and in vivo models through advanced point cloud registration techniques shows great promise for enhancing middle ear diagnostics.
