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.
