摘　　要：为进一步提高临床超声检查质量和方便操作,将纳米技术应用到声检器件是一种可行的新方法。通过对应用于临床的各种现代医学超声检查器件的调查,就其关键部件的医用声感材料的运用现状进行了研究分析。虽然目前超声诊断仪层出不穷并已解决了许多诊断难题,但由于传统的听诊器使用方便且能在临床上解决物理诊断的主要内容,现代医学诊断方法如X光、超声心电图、心音图等仍不能完全替代它。应用新兴纳米技术制备的传声器件及其组件(特别是超声换能器)将会起到提高医用声学检测仪器性能的作用。To improve further the quality of clinical ultrasound and convenient operation,the application of nanotechnology to sound check the new device is a viable method.A variety of modern clinical investigation of medical ultrasound devices is used,the key components of their sound medical sense of the use of the material status of the research and analysis.Although the results of endless Ultrasound diagnosis and has solved many problems,because of the traditional stethoscope easy to use and can solve the clinical diagnosis of the main elements of the physical,modern medical diagnostic methods such as X-ray,ultrasound electrocardiogram,phonocardiogram and so cannot completely replace it.Emerging Nanotechnologies microphone parts and components prepared(especially ultrasonic transducer) will serve to improve the performance of the medical role of acoustic instrumentation.
