To develop a practical, inexpensive system for 3-dimensional ultrasound biomicroscopic imaging of the anterior segment with a commercially available high-frequency ultrasound imager and a personal computer.
Sequential, high-frequency, ultrasound biomicroscopic images of the anterior segment were obtained with a motorized scanning control arm designed in our imaging laboratory. Images were acquired by a personal computer-based video capture device. Ultrasound slice data were then reconstructed as 3-dimensional volumetric images by a personal computer and commercially available software.
Four 3-dimensional visualization formats were developed to enhance the clinical utility of high-frequency ultrasound. Rotational animation sequences were created that detailed the extent and anatomy of a filtering bleb, intraocular lens subluxation, focal angle closure from an iridociliary cyst, intraocular foreign bodies, and an iris tumor.
Three-dimensional, high-frequency ultrasound of the anterior segment enhances our ability to visualize spatial relationships between adjacent anatomic structures. The low cost and ease of use of this system make widespread clinical application practical.
利用市售高频超声成像仪和个人计算机开发一种实用、低成本的眼前节三维超声生物显微镜成像系统。
使用我们成像实验室设计的电动扫描控制臂获取眼前节的连续高频超声生物显微镜图像。图像由基于个人计算机的视频采集设备采集。然后通过个人计算机和市售软件将超声切片数据重建为三维容积图像。
开发了四种三维可视化格式以提高高频超声的临床实用性。创建了旋转动画序列，详细展示了滤过泡、人工晶状体半脱位、虹膜睫状体囊肿导致的局限性房角关闭、眼内异物和虹膜肿瘤的范围及解剖结构。
眼前节的三维高频超声增强了我们可视化相邻解剖结构之间空间关系的能力。该系统的低成本和易用性使其在临床广泛应用成为现实。
