Within a few years 3-dimensional prenatal ultrasound has achieved such a high standard that this technique opens up a new way of image rendering in prenatal diagnosis both for the examiner and for the patient. Using a 3-D ultrasound probe, data acquisition and storage of defined volumes is possible under routine conditions. Within the stored volume every dimension can be visualised and high quality 3-D surface and translucency images can also be provided rapidly. In prenatal diagnosis the advantages are not only in demonstrating precisely the extent of a defect, especially of the surface, but also to convince the parents concerned by clear demonstration of the absence of a specific defect. In 3-D technology there are still some problems to be solved: in severe oligohydramnios, no surface images can be provided, and in the examination of moving objects movement artifacts can occur. On the other hand, improvements in computer technology will soon provide an accelerated image rendering.
在短短几年内，三维产前超声已达到如此高的标准，以至于这项技术为检查者和患者在产前诊断中开辟了一种新的图像呈现方式。使用三维超声探头，在常规条件下可以进行定义体积的数据采集和存储。在存储的体积内，可以可视化每个维度，还能快速提供高质量的三维表面和半透明图像。在产前诊断中，其优势不仅在于精确显示缺陷的范围，尤其是表面缺陷，还在于通过清晰显示不存在特定缺陷来说服相关父母。在三维技术中仍有一些问题有待解决：在严重羊水过少的情况下，无法提供表面图像，并且在检查运动物体时可能会出现运动伪像。另一方面，计算机技术的进步很快将实现加速的图像呈现。
