Standardization of the display of ultrasound images has so far only been achieved in transabdominal two-dimensional (2D) sonography. In contrast, there is a lack of uniformity in the demonstration of transvaginal 2D ultrasound images. The described non-uniformity frequently leads to confusion in the assessment of an image, in particular with regard to the accurate anatomical assignment of left/right and dorsal/ventral. Three-dimensional (3D) sonography offers a unique opportunity to avoid this confusion in the interpretation of ultrasound images, because, independent of primary volume acquisition, the volume can always be rotated so that the stored object can at all times be visualized in a known anatomical position, rendering it of no importance whether the image acquired transvaginally is demonstrated from above or from below. This will also be important in allowing fusion of ultrasound image data with computed tomographic, magnetic resonance and/or positron emission tomography images. In this article we suggest that standardization of transabdominal and transvaginal 3D images does not only provide the inexperienced physician/sonographer with a guide to spatial orientation, but also serves to avoid erroneous topographical interpretations.
迄今为止，超声图像显示的标准化仅在经腹二维（2D）超声检查中得以实现。相比之下，经阴道二维超声图像的展示缺乏一致性。所述的不一致性常常导致图像评估中的混淆，尤其是在左右以及背腹的准确解剖定位方面。三维（3D）超声检查为避免超声图像解读中的这种混淆提供了独特的机会，因为无论初始容积采集如何，容积总能被旋转，从而使存储的物体始终能在已知的解剖位置上被可视化，这使得经阴道获取的图像是从上方还是下方展示变得无关紧要。这对于实现超声图像数据与计算机断层扫描、磁共振和/或正电子发射断层扫描图像的融合也很重要。在本文中，我们认为经腹和经阴道3D图像的标准化不仅为经验不足的医生/超声检查人员提供了空间定位指南，还有助于避免错误的地形学解读。
