The diagnostic ultrasound system is widely used in medicine because of its low cost, handiness and easiness of the treatment. The system can take the image on any cross section in real time and thus we can observe temporal sequential 2-D images easily. For grasping exact 3-D information of organs from these 2-D images, it is necessary to measure the position and the orientation of the probe of the ultrasound device. In this research a magnetic sensor patched on the probe is used to get the positional information of the image plane, We can gather image data on any plane in 3-D space with its positional information, store the images in 3-D space properly, and finally get 3-D tomographic data.We also developed a hardware system which can display the cross sectional image on an arbitrary plane in real time and generate 3-D shapes of organs in quite a short time from 3-D tomographic data stored. The system is built of a hardware system with 3-D memory and a conventional personal computer. The interactive display of 3-D or cross sectional images gives us easy recognition of the internal structure of the organs. By combining these two systems, 3-D data acquisition and visualization, we can build a noninvasive handy system for preinspection of organs in 3-D space.

超声诊断系统以其价格低廉、操作简便、便于治疗等优点在医学领域得到了广泛的应用。该系统可以对任意截面进行真实的实时成像，从而可以方便地观察时间序列二维图像。为了从这些2-D图像中掌握器官的精确3-D信息，需要测量超声设备的探头的位置和取向。本研究采用贴附在探头上的磁传感器来获取像平面的位置信息，利用其位置信息可以采集三维空间中任意平面上的图像数据，并将图像在三维空间中进行适当的存储，并研制了一套硬件系统，可在任意平面上真实的实时显示断层图像，三维形状的器官在相当短的时间内从三维断层数据存储。该系统是建立一个具有3-D存储器和一个传统的个人计算机的硬件系统。交互式显示的三维或横截面图像使我们能够轻松识别器官的内部结构。将三维数据采集和可视化这两个系统结合起来，可以构建一个在三维空间中进行器官预检查的无创便携系统。
