The　design　and　implemention　methods　of　the　computer-aided　system　for　liver　hyperthermia　treatment　planning　were　introduced.　By　the　system,　the　optimal　hyperthermia　treatment　parameters　could　be　achieved　based　on　CT　data　of　liver　cancer　from　301　hospital,　and　reasonable　treatment　planning　could　be　worked　out.　The　experiment　results　indicate　that　the　system　can　be　applied　for　liver　hyperthermia　treatment　planning,　and　is　expected　to　guide　the　process　of　clinical　operation　by　improved　options　in　the　future.
