一種具有超音波溫度影像及彈性影像之高能聚焦式超音波裝置及其使用方法

The invention is disclosed to integrate of ultrasonic temperature-change and elasticity-change to monitor high-intensity focused ultrasound thermal ablation process. A 2-MHz focused ultrasound transducer is employed to produce the thermal lesion ex-vivo. An ultrasound imaging system is employed to acquire RF data for post-processing based on a cross-correlation analysis technique. Estimated thermal lesion size is then quantified and then compared histologically. Preliminary results demonstrate that temperature estimation is beneficial in the monitoring of the entire heating process and improve the specificity of thermal lesion detection.
