Abstract:
In this paper, we present a new method which can reconstruct the three-dimensional model of nasolacrimal duct. We firstly resampled the volume data along nasolacrimal duct direction, then segmented the nasolacrimal duct into slices, and finally, completed the 3D reconstruction from the two-D contours. Using this method, we can not only reconstruct normal nasolacrimal duct, but also reconstruct catagmatic nasolacrimal duct. It overcomes the current shortcomings of some traditional methods. Consequently, the technology proposed is of great significance in computer aided technique and surgical planning related to ophthalmonogy.
