Research on Voyage Path Methods in Medical Visualization
Yan Jun Peng, Yuan Hong Wang · Applied Mechanics and Materials · 2013
A new fast algorithm of voyage path in medical visualization based on distance transform is proposed, which is suitable for single branch and multi-branch objects. A section plane including the next center point is found out according to the location relationship among the present center point on center path, objects start point and end point. The distance from inner voxels to boundary surface is computed in section plane, not in 3D space. The voxel point with the local maximum distance value is taken as the next center point, whose distance value in section plane is larger than its neighbor voxels distance value. It is faster than other algorithms based on distance transform and the results using our algorithm on 2D space and 3D space are given out.
