Magnetic　hyperthermia　ablates　malignant　cells　by　heating　a　tumor　region　when　magnetic　nanoparticles　(MNPs)　are　subjected　to　a　high-frequency　magnetic　field.　The　treatment　effect　for　magnetic　hyperthermia　can　be　evaluated　by　the　mortality　of　malignant　cells,　which　is　mainly　determined　by　the　temperature　profile　of　therapeutic　target,　treatment　duration,　Arrhenius　kinetic　coefficients,　and　also　the　material　of　MNPs.　Both　of　these　interests　should　be　designed　properly　for　a　clinical　consideration.　This　paper　evaluates　the　survival　rate　of　malignant　cells　by　using　an　improved　Arrhenius　model,　in　which　both　treatment　temperature　profile　and　therapeutic　duration　are　all　taken　into　consideration.　The　treatment　temperature　profile　for　a　proposed　geometric　model　is　predicted　by　solving　Pennes　bio-heat　transfer　equation　using　finite　element　method,　in　which　a　heat　source　in　form　of　a　Gaussian　distribution　is　used　as　the　power　dissipation　of　MNPs.　In　addition,　a　kind　of　MNPs　with　low　Curie　temperature　is　considered　to　further　improve　the　therapeutic　effect　for　magnetic　hyperthermia　in　this　paper.　Simulation　results　demonstrate　that　the　temperature　profile　considering　the　MNPs　with　low　Curie　temperature　can　be　more　homogeneous　than　the　case　using　Fe3O4　particles　if　their　power　dissipation　are　increased　properly　with　respect　to　a　critical　value　for　the　Fe3O4　particles.　This　better　distribution　in　treatment　temperature　will　then　result　in　an　obviously　positive　effects　in　malignant　ablation　for　magnetic　hyperthermia.　Meanwhile,　results　also　show　that　the　survival　rate　of　tumor　cells　is　not　only　relevant　to　the　therapeutic　temperature　and　duration,　but　also　depends　more　on　the　kinetic　parameters　due　to　the　individual　characteristic　of　malignant　cells.
