探头

In the experiment, some testing measures are adopted to ensure geting reliable results. For example: coupling liquid is used between the transducer and the specimen to ensure efficient transmission. In order to reduce the system nonlinearity, the loading power of the amplifier is enlarged.

实验过程中还采取了一系列确保超声非线性测量结果可靠性的措施，如：为了减少超声传播过程中的衰减，在压电探头和试样的接触表面加入耦合剂；为了降低实验系统本身产生的非线性，加大了放大器的加载功率。

Vigorouscentral injection of 10 mL of NS however, risks false positiveverification of left lateral precordial probe placement.

但是在中心静脉快速注射10mL 生理盐水会在心前区左侧放置的探头可能产生假阳性的确认。

The error is mainly the system error of the experiment, and the velocity measurement error is the identification of the first arrival of the primary wave and the attenuation measurement is the coupling between the sample and transducer.

对误差分析表明，本文研究中的误差主要来自于实验系统误差，其中速度观测误差来自于对首波初至点的确定，声衰减观测的误差来源于探头与样品之间的耦合状况。

It is important to utilize the correct type of probe.

使用正确的探头类型是很重要的。

Methods Three-dimensional value of the left any right thyroid gland in children were measured by 7.5MHz high frequency prober and the volume were calculated.

采用7.5MHz高频探头，分别测出儿童甲状腺左右叶的三维径值，计算甲状腺的容积。

It is found that imaging by the system is nonlinear duing to SMF,illumination system and reception system both affect the sum optical signal intensity,and optical sectioning strength of the system is depended on prober and SFM.

根据透镜成像规律和单模光纤的传输特性，获得基于单模光纤的共聚焦内窥成像系统轴向光强分布，发现系统的成像过程由于单模光纤的介入呈现非线性，照明光路系统和接收光路系统仅影响系统接收信号的总强度，系统层析能力取决于探头和单模光纤性能。

The prober (7.5MHz) was used in operation to detect the liver in 106 patients with liver tumor. The intraoperative ultrasound showed obvious advantages for small focus.

对106例肝脏肿瘤患者，术中采用7.5MHz的超声探头，直接在肝脏表面按次序、全方位对肝脏内结构进行扫查。
