The development and early clinical results of a real-time color B-scan ultrasonoscope are described. This instrument uses color to display detailed echo amplitude information more quantitatively than is possible with gray scale. With real time, dynamic changes are seen during the examination. Conversion of the amplitude information into binary coded decimal code permits separation into ten color steps and also eliminates "blooming" of the cathode ray tube, as seen in black and white. Integrated circuitry is used, providing a portable, relatively inexpensive unit. Early clinical work in ophthalmology is illustrated.
本文描述了一种实时彩色B型超声诊断仪的研制情况及早期临床应用结果。该仪器利用颜色比灰度更定量地显示详细的回波幅度信息。具备实时功能，在检查过程中可观察到动态变化。将幅度信息转换为二进制编码十进制代码可分成十个颜色等级，还消除了阴极射线管的“图像重叠”现象，这在黑白显示中较为常见。采用了集成电路，制成了便携式、成本相对较低的仪器。文中还举例说明了该仪器在眼科的早期临床应用情况。
