摘要 寻找一种实时、无创的温度检测技术是目前癌热疗技术应用中面临的主要课题。在研究生物组织超声回波时移与其温度相关性的基础上,设计超声波高速数据采集与处理系统,利用这种相关性来无创检测癌热疗中组织温度的变化。该系统主要由超声发射接收器、高速AD采集卡和微型计算机组成,能检测不同温度下组织背向反射超声波的回波时间,实现了组织温度的实时测量与显示。 Objective The noninvasive estimation of tissue temperature is a key problem in hyperthermia. The correlation of echo shifts of backscattered ultrasound and temperature in tissue was studied. A ultrasound signal sampling and processing system was designed with the theory that the echo shifts of backscattered ultrasound varied in accordance with the temperature changes in tissues, and the correlation may be used to estimate the heated tissue temperature in hyperthermia. Corresponding to the ultrasonic noninvasive thermometry, a signal sampling and processing system was established, which mainly consists of ultrasound emitter and receiver, high speed AD clip and PC. The time delay of backscattered ultrasound can be detected and temperature of tissue can be measured and displayed in the thermometry system.
