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)超声成像系统。它使用了一种特殊的三维超声波扫描仪，带有一个凸起的电子控制电机驱动的换能器。可以拍摄128个二维(2D)回声平面，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。该系统速度快，使用方便，并提供高质量的图像。此外，三维回声数据可以显示为静止或运动图像。可以获得正常胎儿或异常情况和结构的良好三维图像，如无脑儿合并脑膜脑、肝硬变、肝细胞癌、胆结石、腹膜后肿瘤、腹主动脉瘤、肾癌和膀胱癌。而且，随着速度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、容易，一次扫描就可以搜索整个上腹部。三维图像数据可以在4秒或更短的时间内传输到三维处理系统(XA-980)。转换成三维图像是流畅和准确的，三维图像的数据可以在需要的时候使用。通过从CRT监视器上显示的选项中进行选择，可以用计算机鼠标操作该系统。这些包括动画、鸟瞰、鸟瞰+表面、中心或平行投影、凸面图像、绘制、内窥镜观察、表示项目时间、指示、线性图像、记忆、定期项目时间、屏幕移动、截面移动、选择截面、选择视点、设置、静止、数据文件、表面视图、接收回波、三平面显示、血管和腔显示以及其他命令。

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.
