目的：本报告的目的是描述三维 (3-D) 超声成像技术及其对改善眼部疾病诊断和监测的影响。设计：作者回顾了获取和显示眼部 3-D 超声数据的技术，参与者：作者将这些技术应用于代表性的个案，包括脉络膜出血、睫状体黑色素瘤、睫状体脱离、后房型人工晶状体移位以及正常眼的地形分析。角膜，干预：计算机控制的运动系统用于执行甚高频 (VHF) (50 MHz) 和传统 (10 MHz) 数字 3-D 超声数据收集。扫描系统允许对一系列平行平面的超声数据进行数字化。可以交互地操作 3D 数据，以获得通过扫描体积的任何平面中的二维图像。 3D 图像是通过体积渲染构建的，可以定位以从多个角度进行查看。代表声散射体特性的 3-D 超声参数图像是通过数字化回波数据的频谱分析生成的。通过 3D 回波数据的数字信号处理生成代表中央角膜上皮和基质的轮廓和厚度的彩色图。结果：定量体积测量和生物识别技术增强了 3D 超声图像中的诊断和治疗计划信息内容。通过实体模型显示脉络膜上腔内出血和血栓的位置和范围。记录睫状体黑色素瘤体积随时间的变化，并观察与放射治疗相关的 3D 超声参数图像变化。在睫状体脱离中，显示了脱离的程度。后房型人工晶状体的实体模型显示触觉相对于晶状体囊残余物的错位。角膜厚度图显示了角膜厚度和局部曲率半径测量的范围和方差。结论：定量体积测量和生物识别工具与 3D 超声图像分割相结合，通过改进组织结构的定位，提高了 3D 超声图像的诊断和治疗计划信息内容。
Objective: The aim of this report is to describe the technology of three-dimensional (3-D) ultrasonic imaging and its impact on improved diagnosis and monitoring of ocular disease.Design: The authors reviewed techniques for acquiring and displaying 3-D ultrasound data of the eye,Participants: The authors applied these techniques to representative individual cases, including a choroidal hemorrhage, a ciliary body melanoma, a ciliary body detachment, a displaced posterior chamber intraocular lens, and topographic analysis of a normal cornea,Intervention: A computer-controlled motion system was used to perform very high-frequency (VHF) (50-MHz) and conventional (10-MHz) digital 3-D ultrasound data collection. The scanning system allowed digitization of ultrasound data from a series of parallel planes. The 3-D data could be manipulated interactively to obtain two-dimensional images in any plane through the scan volume. The 3-D images were constructed by volume rendering and could be positioned for viewing from a variety of perspectives. The 3-D ultrasound parameter images representing acoustic scatterer properties were generated by spectrum analysis of digitized echo data. Color maps representing the contour and thickness of the epithelium and stroma of the central corneal were generated by digital signal processing of 3-D echo data,Results: Quantitative volume measurement and biometric techniques enhanced the diagnostic and treatment planning information content in 3-D ultrasound images. The location and extent of hemorrhage and clots within the suprachoroidal space were shown with solid modeling. Volume changes in ciliary body melanoma over time were documented and 3-D ultrasound parameter image changes associated with radiation therapy observed. In ciliary body detachment, the extent of the detachment was shown. Solid modeling of a posterior chamber intraocular lens showed misplacement of the haptic in relation to the lens capsule remnants. Keratopachymetric maps showed the range and variance of thickness and local radius of curvature measurements in the cornea.Conclusions: Quantitative volume measurement and biometric tools combined with segmentation of 3-D ultrasound images improve diagnostic and treatment planning informational content of 3-D ultrasound images through improved localization of tissue structures.
