Medical　image　segmentation　and　3D　mesh　generation　are　the　two　critical　challenges　for　numerical　analysis　based　on　medical　images.　Seamlessly　linking　different　segmented　results　to　appropriate　mesh　generation　algorithms　should　be　greatly　beneficial　for　automatic　and　rapid　finite　element　modeling　from　medical　images.　We　present　the　interface　representation　models　between　segmentation　and　mesh　generation　algorithms　and　briefly　discuss　the　input　requirements　of　several　well-established　meshing　algorithms.　©2009　IEEE.
