[Objective]　To　get　three-dimensional　(3-D)　surface　visualization　results　of　the　liver　and　tumors　by　Amira(MERCURY,USA)　for　liver　hyperthermia　treatment　planning.　[Methods]　Liver　CT　slices　obtained　from　Chinese　PLA　General　Hospital　were　loaded　into　Amira,　and　then　image　preprocessing(image　registration,　cropping,　segmentation)　was　accomplished　by　Amira.　At　last　3-D　visualization　results　were　acquired　by　Amira＇s　modules　and　editors.　[Results]　The　3-D　reconstruction　results　were　satisfying,　and　3-D　physical　peculiarities　of　liver　structures　could　be　obtained.　[Conclusion]　3-D　physical　parameters　of　the　liver　and　tumors　were　obtained　from　reconstruction　surface　results,　which　could　be　applied　to　simulate　the　distribution　of　temperature　field　and　helped　to　choose　the　most　suitable　hyperthermia　parameters　for　liver　cancer　treatment.　So　the　research　can　provide　scientific　and　reliable　evidences　for　hyperthermia　treatment　planning　and　guide　the　process　of　clinical　operation.　©　2008　IEEE.
