Hyperthermia　is　a　significant　and　promising　technique　for　tumor　treatment.　Temperature　is　the　key　parameter　which　influences　the　treatment　effectiveness.　Therefore,　real-time　and　precise　noninvasive　temperature　monitoring　is　the　pivotal　issue　in　further　development　of　hyperthermia.　This　paper　introduced　the　noninvasive　monitoring　theories　and　techniques　of　hyperthermia　based　on　ultrasonic　image　texture　features,　and　reviewed　the　achievements　both　abroad　and　at　home.　In　addition,　some　problems　to　be　solved　necessary　were　also　pointed　out.
