Study on the High Speed Treatment and Quantitative Analysis of the Three-Dimensional Echography

我们开发了一种新的三维（3D）超声系统。它使用一种特殊的三维超声波扫描仪，带有一个凸起的、电子控制的、电机驱动的换能器。可以拍摄128个二维（2D）超声平面，并且可以在不到4秒的时间内将制作三维图像所需的大量信息传输到计算机。该系统快速，易于使用，并提供高质量的图像。此外，三维超声数据可以显示为静止或动画图像。正常胎儿或无脑畸形伴脑膜脑炎、肝硬化、肝细胞癌、胆结石、腹膜后肿瘤、腹主动脉瘤、肾癌、膀胱癌等异常情况和结构均可获得良好的三维图像。此外，随着更快的计算机的出现，处理三维超声图像所需的时间应该会减少。三维扫描仪操作流畅、简便；单次扫描可搜索整个上腹部。三维图像的数据可以在4秒或更短时间内传输到三维处理系统（XA-980）。转换成三维图像平滑准确，三维图像的数据可以随时使用。该系统可以通过电脑鼠标从CRT显示器上显示的选项中进行选择来操作。包括动画、鸟瞰图、鸟眼+曲面图、中心或平行投影、凸面图、绘制、内视图、表示项目时间、指示、线性图像、记忆、常规项目时间、屏幕移动、剖面移动、选择剖面、选择视点、设置、静止、数据文件、曲面视图、接收回声、三面显示、管腔显示等命令。

We developed a new system for three-dimensional (3D) echography. It uses a special three-dimensional ultrasonic scanner with a convex, electronically controlled, motor-driven transducer. One hundred twenty-eight two-dimensional (2D) echographic planes can be taken and the large amount of information required for making three-dimensional images can be transferred to a computer in less than 4 seconds. The system is fast, easy to use, and provides images of high quality. Moreover, the three-dimensional echographic data can be displayd as still or animated images. Good three-dimensional images of normal fetuses or such abnormal conditions and structures as anencephaly with meningocepharus, liver cirrhosis, hepatocellular carcinomas, gallstones, retroperitoneal tumors, abdominal aortic aneurysms, renal carcinomas, and urinary bladder carcinomas can be obtained. Moreover, the time required to process three-dimensional echogrphic images should decrease as faster computers become available.Operation of the three-dimensional scanner was smooth and easy ; the entire upper abdomen could be searched at single scanning.Data for three-dimensional images can be transferred to the three-dimensional processing system (XA-980) in 4 seconds or less. Translation into three-dimensional images is smooth and accurate, and data for three-dimensional images can be used whenever needed. This system can be manipulated with a computer mouse by selecting from among the choices presented on the CRT monitor. These include animation, bird's-eye view, bird's-eye-plus-surface view, center or parallel projection, convex image, draw up, endoscopic view, express project time, indication, linear image, memory, regular project time, screen travel, section travel, select section, select viewpoint, set up, stationary, data file, surface view, take in echo, triplane display, vessel-and -cavity display, and other commands.
