Abstract

The pros and cons of the various B-scan modes are discussed, and the preferences of the combination of the linear scan and the arc scan is eludicated with experimental results. Some techniques of modulation of the intensity of the B-scan oscilloscope are compared, the starting point being an A-scan equipment with a logarithmic gain amplifier. It is concluded that either a differentiated video signal, or a system employing standard pulses are differentiation of the video signal, or a system employing standard pulses after differentiation of the video signal enhances the anatomical outlining of the B-scan pictures. In order to provide quantitative information of the echo-pattern, A-scan pictures have to be made. These pictures are taken at positions with the B-scan display.

超声眼科检查的方法和临床方面。
讨论了各种b扫描方式的优缺点,并结合实验结果阐述了线性扫描和弧线扫描相结合的选择。以带对数增益放大器的a扫描示波器为例,比较了b扫描示波器强度调制的几种技术。得出结论:无论是差分视频信号,还是采用标准脉冲的系统都是对视频信号进行差分,或者是在对视频信号进行差分后采用标准脉冲的系统增强了b扫描图像的解剖轮廓。为了提供回声模式的定量信息,必须制作a扫描图像。这些照片是在b扫描显示的位置拍摄的。
