【Abstract】 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.更多还原
