We have gotten a skeleton data of a hippocampal boundary surface, the skeleton (medial sheet) contains a triangular surface, then we want to get a grid (volume) data of this medial sheet to do the three-dimensional mapping between hippocampal boundary and that medial sheet using Laplacian equation. I have tried the SurfStat tool (SurfStatSurf2Vol, specifically) developed by MNI, McGill University, but the voxelized skeleton is not continual. Are there some methods to deal with this issue?
Any suggestions are welcome! Thank you very much!
