不管是哪种超声波诊断装置,根据其电路结构来分,则大致由图2.1所示的部分来构成。下面就以日本日立医疗器械公司(Hi-tach Medicalcop)所生产的EUB—40超声波诊断装置做为样机,做一个较详细的电路分析。这种机型在国内用户较多,是一种多功能的诊断装置,只要对EUB—40的电路及原理有了了解之后,对其它机型的电路分析也就不困难了。 2.1 超声部分总框图概述日立EUB—40的超声部分总框图如图2.1.1所示,由图中所示的各电路板组成。 1.探头:EUB—40超声波诊断装置可同时安装一只线性探头、一只凸阵探头、一只机
Regardless of the type of ultrasonic diagnostic apparatus, it is roughly divided by the portion shown in FIG. 2.1 depending on the circuit configuration. Below to Japan’s Hitachi Medical Devices (Hi-tach Medicalcop) produced EUB-40 ultrasound diagnostic device as a prototype, to do a more detailed circuit analysis. This model is more users in the country, is a multi-functional diagnostic device, as long as the circuit and the principle of EUB-40 has been understood, the circuit analysis of other models is not difficult. 2.1 Overview of Ultrasonic Block Diagram The general block diagram of the ultrasound section of Hitachi EUB-40 is shown in Figure 2.1.1 and consists of the circuit boards shown in the figure. 1. Probe: EUB-40 ultrasonic diagnostic device can be installed simultaneously with a linear probe, a convex array probe, a machine
