Three-Dimensional Liver Reconstruction Based on Marching Cube and Revised Laplacian Smoothing

In the three-dimensional liver reconstruction, in order to decrease shrinkage and make up the lost important details in Laplacian smoothing, we make some improvements to revise the algorithm in this paper.The cost function after Laplacian smoothing process is constructed to make up the lost important details. When the value of cost function is minimum, the result is close to original liver volume. From the results, we can see that volume of the revised algorithm is more closely to the original volume compared with Laplacian smoothing algorithm.
