摘要：

The　purpose　of　this　paper　is　to　study　a　kind　of　noninvasive　temperature　measure　method,　which　based　on　shifts　in　echo　location　of　backscattered　ultrasound　from　heated　tissue,　in　our　experiments,　the　correlation　of　shifts　in　echo　location　of　backscattered　ultrasound　and　temperature　in　tissue　was　studied.　The　experiments　were　carried　out　on　degassed　water　and　in-vitro　fresh　liver　tissue　of　pig　during　the　temperature　range　from　20°C-50°C,　and　a　series　of　shifts　in　echo　location　of　backscattered　ultrasound　were　obtained　in　different　temperature,　ft　has　been　found　that　the　shifts　in　echo　location　of　backscattered　ultrasound　varied　in　accordance　with　the　temperature　changes　in　tissue,　and　this　correlation　may　be　used　to　estimate　the　heated　tissue　temperature　in　hyperthermia.
