随着科学技术的迅猛发展,超声诊断已经成为临床诊断上的一个非常必要的手段。它具有诸如无侵袭伤害、不影响人体健康、适应性广等优点。其中,B型超声系统已经成为广泛应用的医学检查手段,它以超声图像技术为中心,并且在临床各个领域中的应用日趋普遍。它的发展迅速,也充分显示出其在各类疾病中的应用价值。但是,由于B超系统的结构复杂、故障频繁、设备引进时多数没有维修手册,所以给后期的设备维修带来了很大麻烦和困扰。通过本文,我们可以深入了解到B超仪器的工作原理、详细地分析系统基本结构和信号流程、判断故障点并予以排除。
With the rapid development of science and technology, ultrasonic diagnosis has become a very necessary tool in clinical diagnosis. It has such as no invasion, does not affect human health, wide adaptability and so on. Among them, B-type ultrasound system has become a widely used means of medical examination, which ultrasound image technology as the center, and in various fields of clinical application of the increasingly common. Its rapid development, but also fully demonstrated its value in various diseases. However, due to the complicated structure of the B-mode system and the frequent faults, the majority of the equipment is not provided with a maintenance manual at the time of introduction, which brings great troubles and troubles to the later equipment maintenance. Through this article, we can in-depth understanding of the working principle of B-ultrasound equipment, a detailed analysis of the basic structure of the system and signal flow, determine the point of failure and be ruled out.
