项目摘要

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.

我们开发了一种新的三维（3D）回波描记系统。它使用一个特殊的三维超声扫描仪，带有一个凸形的、电子控制的、电机驱动的换能器。可以拍摄128个二维（2D）回波平面，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，三维回波描记数据可以显示为静止或动画图像。可以获得正常胎儿或诸如无脑儿伴脑膜头畸形、肝硬化、肝细胞癌、胆结石、腹膜后肿瘤、腹主动脉瘤、肾癌和膀胱癌等异常情况和结构的良好三维图像。此外，随着计算机速度的提高，处理三维回波图像所需的时间也会减少。一次扫描可搜索整个上腹部。三维图像的数据可在4秒或更短时间内传输到三维处理系统（XA-980）。转换为三维图像是平滑和准确的，并且用于三维图像的数据可以在任何需要的时候使用。该系统可以通过计算机鼠标从CRT显示器上显示的选项中进行选择来操作。这些包括动画、鸟瞰视图、鸟瞰加表面视图、中心或平行投影、凸图像、绘制、内窥镜视图、表达投影时间、指示、线性图像、存储器、常规投影时间、屏幕行程、切片行程、选择切片、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。
