虽然超声是一种重要的高性价比成像手段，但在充分发挥其用于准确和可重复性监测疾病进展或消退的潜力之前，还需要技术上的改进。使用常规超声对三维解剖的二维观察限制了我们量化和可视化病理的能力，并且部分原因是在诊断和监测疾病进展方面报道的可变性。研究人员的努力集中在通过开发3D超声成像技术来克服这些缺陷，该技术能够使用现有的常规超声系统获取B型图像，将信息重建为3D图像，然后允许在廉价的台式计算机上交互查看3D图像。此外，3D超声图像的可获得性使手动和半自动技术的发展成为可能，以量化正常和异常的解剖体积。在这篇文章中，我们回顾了我们的半自动3D分割方法，用于分割颈动脉和斑块的表面，以及分割前列腺。这些技术表明，有效的分割技术可以用于3D超声图像来量化解剖器官的体积和形态。
Although ultrasonography is an important cost-effective imaging modality, technical improvements are needed before its full potential is realized for accurate and reproducible monitoring of disease progression or regression. Two-dimensional viewing of three-dimensional anatomy, using conventional ultrasonography, limits our ability to quantify and visualize pathology and is partly responsible for the reported variability in diagnosis and monitoring of disease progression. Efforts of investigators have focused on overcoming these deficiencies by developing 3D ultrasound imaging techniques that are capable of acquiring B-mode images using existing conventional ultrasound systems, reconstructing the information into 3D images, and then allowing interactive viewing of the 3D images on inexpensive desktop computers. In addition, the availability of 3D ultrasound images has allowed the development of manual and semi-automated techniques to quantify normal and abnormal anatomical volumes. In this paper we review our semi-automated 3D segmentation approaches for segmenting the surface of the carotid arteries and plaques, and segmenting the prostate. These techniques demonstrate that efficient segmentation techniques can be used with 3D ultrasound images to quantify anatomical organ volumes and morphology.
