Abstract：

The　temperature　field　of　thermal　ablation　induced　by　a　water-cooled　microwave　antenna　was　numerically　studied.　The　specific　absorption　rate　(SAR)　distribution　was　experimentally　determined　in　the　phantom　and　analytically　fitted,　which　was　used　as　a　heat　generation　rate　in　the　following　numerical　simulation.　An　axis-symmetric　finite　element　model　was　developed　to　simulate　the　temperature　field,　in　which　the　convection　heat　transfer　of　the　cooling　water　was　involved.　Thus,　the　characteristics　of　the　interested　microwave　antenna　were　well　understood　to　instruct　the　clinical　operation　and　surgical　planning　of　microwave　ablation　in　practice.　©　2007　IEEE.
