英文摘要 | In this paper, we propose a method of reconstructing triangular surfaces from given medical slices. The method tries to solve the problem by using contours interactively extracted from the slices. After that the problem changes to connecting the contours into a triangular mesh. For the purpose, the algorithm has to deal with two difficult problems: contour correspondence and branching. The correspondence problem is solved here by exploiting information both of the extracted contours and the original slices. Then, we triangulate the contours by a piecewise-linear interpolation scheme with ability to handle degenerate portions in the mesh. The most significant advantage in integrating the grey-level slice information is that we can match the contours more correctly to find reliable contour correspondence for modeling complex anatomical structures.; EI; 0 |
