项目摘要

A system for 3-D ultrasonic imaging using a graphic computer has been developed for the fetus in utero. The advantages of 3-D ultrasonic images over the conventional tomographic images have been investigated by applying it to the following clinical situations.1) Fetus; The new system could clearly depict subtle morphological abnormalities, such as fetal face, as well as polydactyly.2) Placental Blood Flow; A color Doppler ultrasound was used to acquire contiguous blood flow images of the placenta. These images were processed by the computer in the same manner as fetal 3- D imaging. The3-D blood flow imaging demonstrated placental blood flow distribution, which was thought to have the potential to provide good information on placental circulation and to be helpful in predicting fetal growth abnormalities caused by placenta dysfunction.3) Breast; Three real time image processors were applied for the preprocessing of breast tumor images. Unlike the fetus in amniotic fluid, breast tumors are difficult to distinguish from the surrounding breast tissue. The real time image processors were controlled by a microcomputer and could reduce the noise generated by the surrounding tissue. 3-D images of breast cancers, cysts and fibroadenomas were displayed distinctly. The 3-D images were favorable for differentiating between benign or malignant breast lesions. Computer generated 3-D ultrasonic images can further supplement the contiguous tomographic images. The technique has great promise in fetal imaging and might find usefulness in investigations concerning fetal blood flow and breast screening.

本文介绍了一种利用图形计算机对宫内胎儿进行三维超声成像的系统。通过将其应用于以下临床情况，研究了3-D超声图像相对于传统断层图像的优势。1）胎儿;新系统可以清楚地描绘细微的形态异常，例如胎儿面部以及多指畸形。2）胎盘血流;彩色多普勒超声用于获取胎盘的连续血流图像。这些图像由计算机以与胎儿3- D成像相同的方式处理。三维血流成像显示了胎盘血流分布，为胎盘循环提供了良好的信息，有助于预测胎盘功能障碍引起的胎儿生长异常。3）乳腺：采用3个真实的实时图像处理器对乳腺肿瘤图像进行预处理。与羊水中的胎儿不同，乳腺肿瘤很难与周围的乳腺组织区分开来。真实的实时图像处理器由微机控制，可降低周围组织产生的噪声。乳腺癌、囊肿、纤维腺瘤的三维图像显示清晰。三维图像有利于乳腺良恶性病变的鉴别。计算机生成的三维超声图像可以进一步补充相邻的断层图像。该技术在胎儿成像方面有很大的前景，并可能在有关胎儿血流和乳房筛查的调查中发现有用的。
