Simple experiments which form the basis for a true 3-D demonstration of sectional images are presented and a method for genuine 3-D display of dynamic ultrasound images is described. Eight ultrasound images are recorded with a slightly different angulation of the transducer. The images are extracted from the video signal from a conventional ultrasound scanner and stored in eight digital memories. After recording, each image is displayed on an oscilloscope screen, which is viewed via a fast oscillating mirror. The position of the mirror determines which of the eight images are to be displayed and thereby ensures a correct spatial relationship of the images, resulting in a true 3-D scan presentation.
介绍了构成断层图像真实三维演示基础的简单实验，并描述了一种动态超声图像的真实三维显示方法。用换能器以稍有不同的角度记录八幅超声图像。这些图像从传统超声扫描仪的视频信号中提取并存储在八个数字存储器中。记录后，每幅图像显示在示波器屏幕上，通过快速振荡镜进行观察。镜子的位置决定显示八幅图像中的哪一幅，从而确保图像的正确空间关系，产生真实的三维扫描呈现。
