Software of 3D reconstructions for medical images is basically focused on the application of visualization. Few people
have studied the techniques and software about numerical simulation oriented 3D reconstructions for medical images
that mainly solve the problems such as visualization for 3D reconstructions, model modifying and mesh generation for
finite element analysis. These issues were reviewed and analyzed, the development toolkits were introduced, and some
attentive questions and their corresponding solutions as well as some new perspectives were proposed.
