| 中文摘要: |
| 超声治癌已获得愈来愈多的重视和发展.超声温热疗法和烧蚀疗法都要求作温度监测.有损测温法会碰到难以克服的困难.本文论述无损测温的研究和发展,提供几种无损测温方法.这些是:(1)穿透超声渡越时间法;(2)有限元法(或差分法,或细胞神经网络法)解热传导边值问题法;(3)超声CT法;(4)反射超声时频图分析法等. |
| 英文摘要: |
| Ultrasonic treatment of tumors has got an increasingly widespread concern and development in the world nowadays.In ultrasonic therapeutical treatments both by hyperthermia and pyrotherapy,the temperature detection and monitoring are always needed due to optimum of curative effect.The invasive monitoring has some clearly unsurmountabe drawbacks.There fore,the methods for noninvasive estimation of temperature inside tumor are presented here as follows:(1)method of measuring time-of-flight of ultrasound pulses;(2)finite element(or difference or cellular neural network)method of solving the boundary value problem with respect to bioheat transfer equation;(3)method of ultrasound computed tomography;(4)method by ultrasound echo pulses based on Wigner Distribution Diagram analysis. |
