To　summarize　noninvasive　monitoring　methods　for　tumor　ablation　based　on　ultrasonic　tissue　characterization　in　recent　years,　a　variety　of　monitoring　methods　for　thermal　ablation　treatment　were　discussed　based　on　ultrasonic　elasticity　imaging　technology　and　quantitative　ultrasound　technology.　The　monitoring　principle,　experimental　design　and　monitoring　result　were　summarized,　and　the　applicability　and　limitations　of　every　method　were　discussed.　Result　shows　that　there　are　no　methods　that　can　be　applied　directly　to　the　clinic　because　of　the　limitations　of　the　precision,　cost,　property　of　the　real　time　and　other　conditions.　In　the　future,　a　method　that　can　achieve　intraoperative　monitoring　and　postoperative　efficacy　evaluating　should　be　put　forward,　combined　with　the　existing　ultrasound　equipments　and　applied　to　clinic.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
