Three-dimensional sonography is a logical development of conventional sonography, and is a consequence of the fact that every examiner tries to imagine the three-dimensional appearance of an organ on the basis of the tomographic images of it. In a long development process starting with the first 3D images in 1986/87 and lasting until today, we succeeded in developing a 3D system suitable for routine examinations, which the manufacturer is now marketing commercially. With a 3D transducer a coordinated sequence of tomograms is obtained; all the images are then computed transparently and subsequently imaged three-dimensionally as a crystalline volume. Movement of the 3D image on the computer screen is important for three-dimensional identification. The volume thus computed can then be bisected in longitudinal, transverse and horizontal planes and thus examined in real-time without any interference such as fetal movements. The horizontal sections cannot be obtained by conventional sonography. On the basis of more than 600 patients examined by this new method it was established that 3D imaging of malformations improves diagnosis and assessment, that examinations deliver accurate and reproducible results, and that section analysis can substantially facilitate diagnosis of fetal malformations.
三维超声检查是传统超声检查的合理发展，这是因为每个检查者都试图根据器官的断层图像来想象其三维外观。在从1986/87年的首张三维图像开始并持续至今的漫长发展过程中，我们成功开发出了一种适用于常规检查的三维系统，目前制造商正在进行商业推广。使用三维换能器可获得一系列协调的断层图像；然后对所有图像进行透明计算，并随后作为晶体容积进行三维成像。计算机屏幕上三维图像的移动对于三维识别很重要。这样计算出的容积随后可以在纵向、横向和水平平面上进行平分，从而在没有诸如胎儿运动等任何干扰的情况下进行实时检查。传统超声检查无法获得水平截面。基于通过这种新方法检查的600多名患者，证实畸形的三维成像可改善诊断和评估，检查可提供准确且可重复的结果，并且截面分析可极大地促进胎儿畸形的诊断。
