Great strides have recently been made in obstetrics and gynaecology secondary to the development of high-performance transvaginal ultrasound (TVS) instruments. However, even this advanced technology can provide only two-dimensional (2D) views of three-dimensional (3D) structures. Although an experienced examiner can easily piece together sequential 2D planes for creating a mental 3D image, individual sectional planes cannot be achieved in a 2D image because of various difficulties. Today, 3D TVS can portray not only individual image planes, it can also store complex tissue volumes which can be digitally manipulated to display a multiplanar view, allowing a systematic tomographic survey of any particular field of interest. The same technology can also display surface rendering and transparency views to provide a more realistic 3D portrayal of various structures and anomalies. The current review provides examples and discussions of the various applications in obstetrics, gynaecology and assisted reproduction in which 3D TVS is a useful supplement to image modality.
近年来，随着高性能经阴道超声（TVS）仪器的发展，妇产科学取得了巨大进步。然而，即使是这种先进技术也只能提供三维（3D）结构的二维（2D）视图。尽管经验丰富的检查人员可以轻松地将连续的二维平面拼凑在一起，以形成一个三维心理图像，但由于各种困难，二维图像中无法获得单个截面平面。如今，三维经阴道超声不仅可以描绘单个图像平面，还可以存储复杂的组织容积，这些容积可以进行数字处理以显示多平面视图，从而对任何特定感兴趣的区域进行系统的断层扫描。同样的技术还可以显示表面渲染和透明视图，以提供各种结构和异常的更逼真的三维描绘。本综述提供了三维经阴道超声在妇产科学和辅助生殖中的各种应用的示例和讨论，其中三维经阴道超声是一种有用的图像模态补充。
