项目摘要

In the field of cardiology, echocardiography, as a noninvasive and handy method, is widely used for observing the motion of the heart. But usually it is used only rough observation of the motion of the left ventricle or other parts of the heart. Only a few quantitative analyses by using a computer system have been done in the field of cardiology. The main purpose of this research was to develop an image processing system of echocardiograms which is usable in clinical fields.The system is built of a conventional personal computer system (PC) and a memory box for echo-data storage connected to the computer through the system bus of PC. The operation of the system by a medical doctor is done by choosing a task on an appropriate menu which is selected by the computer according to the situation.The system can perform the following tasks; 1) digitize echo signal and save them in the frame memory box directly from the echocardiographic device or from a video tape recorder through a video tape, 2) detect the shapes of the left ventricle in a cardiac cycle, 3) calculate various parameters for the cardiac function and 4) display the results of cardiac function.The necessity of the data. processing of echocardiograms especially in the field of clinical applications will increase more and more in recent future. The system developed in this research is compact and easy to handle. The system should be improved in software through the feedback from the clinical fields. Moreover, the development of a system in more compact size, such as a one-board interface card for a personal computer, is the urgent problem for clinical use in a wide area.

在心脏病学领域，超声心动图作为一种无创、简便的方法，被广泛用于观察心脏的运动。但通常它只用于粗略观察左心室或心脏其他部位的运动。在心脏病学领域中，只有少数使用计算机系统进行定量分析。本研究的主要目的是研制一种可用于临床的超声心动图图像处理系统，该系统由一台普通的个人计算机系统（PC）和一个通过PC系统总线与PC相连的存储器组成。医生对系统的操作是通过在计算机根据情况选择的适当菜单上选择任务来完成的。1）直接从超声心动图装置或从录像机通过录像带将回波信号截取并保存在帧存储盒中，2）检测心动周期中左心室的形状，3）计算心脏功能的各种参数和4）显示心脏功能的结果。数据的必要性。在最近的将来，超声心动图的处理，特别是在临床应用领域中的超声心动图的处理将越来越多地增加。本研究所开发的系统结构紧凑，易于操作。通过临床领域的反馈，系统应在软件上进行改进。此外，开发尺寸更紧凑的系统，例如个人计算机的单板接口卡，是广泛临床应用的紧迫问题。
