摘要
介绍了自制的超声肿瘤热疗系统。该系统有九个功率放大器分别给九个超声换能器提供能源,利用九路测温系统实时采集体内九点温度值。依据温度数据的反馈,能及时地对各路功率放大器输出的功率进行调整,以保证热疗达到预期的效果。
A report on a system designed by us, is made in this paper, which has the real time temperature monitoring function and auto-adjusting acoustic power output function. The system has a nine-element transducer array and each element can be controlled independently. Temperature signals are gathered by nine acicular mircroprobes and the bar charts and curve charts can be illustrated in real time. According to the temperature signal, the system can intelligently adjust the acoustic output so as to achieve effective therapy.
