高能聚焦超声热疗属热疗的一种,它的英文缩写为HIFU,又称“隐形超声刀”。此热疗技术采用的致热能量为超声波,它不同于其它的致热高频波,超声波具有穿透深度大、指向性强、聚焦性好、皮肤及皮下脂肪组织不过热等优点。采用体外聚焦技术将数百束超声波聚集起来,经水介质耦合作用,聚焦点指向体内肿瘤组织,其温度达到70～100摄氏度,可在0.25～0.1秒内“烫”死癌细胞,即瞬间杀死3×3×10立方毫米的肿瘤组织,使瘤细胞核凝固坏死。超声热疗
High-energy focused ultrasound hyperthermia is a kind of hyperthermia, its English abbreviation is HIFU, also known as “invisible ultrasonic knife.” The heat energy used in this hyperthermia technique is ultrasound, which is different from other high-frequency waves that cause heat. Ultrasound has the advantages of large penetration depth, strong directivity, good focusing, and not too little skin and subcutaneous fat tissue. The use of in vitro focusing technology to gather hundreds of ultrasound waves, coupled by the water medium, the focus point to the tumor tissue in the body, the temperature reached 70 to 100 degrees Celsius, can be “hot” in 0.25 to 0.1 seconds of dead cancer cells, that is, instant kill 3 × 3 × 10 cubic millimeters of dead tumor tissue, so that the tumor cell nuclei coagulation and necrosis.
