This is the first report on the 3-dimensional representation of organs with US. The prerequisite for this was a coordinated transducer movement, in such a manner that the organ under examination was represented by US sections differing in only one of the space coordinates. Such transducer movement was made possible by 2 devices. In the first instance, longitudinal movement of the transducer resulted in the production of parallel sections of the organ while, in the other instance, rotation of the transducer head permitted sections arranged around a fixed center-point. Using a special computer program, the sections were contoured in such a manner that only the surface of the organ was represented. These sections were then arranged in space. The 3-dimensional representation can be effected both by binary image representation and by representation with closed (intact) body surface. The advantage of the binary image representation is the fact that the organ surfaces "extracted" from the original US sections are directly incorporated within the 3-dimensional image build-up, with no further computer manipulations. It can be seen that the rotation of the transducer head represents the practicable possibility for the use in the clinical setting.
这是关于用超声对器官进行三维成像的首份报告。其前提是换能器的协同移动，使得被检查器官由仅在一个空间坐标上不同的超声切面来呈现。换能器的这种移动通过两种设备得以实现。首先，换能器的纵向移动可产生器官的平行切面，而在另一种情况下，换能器头部的旋转能得到围绕固定中心点排列的切面。使用一个特殊的计算机程序，对这些切面进行轮廓描绘，使得仅呈现器官的表面。然后将这些切面在空间中排列。三维成像既可以通过二值图像呈现，也可以通过具有封闭（完整）体表的呈现方式来实现。二值图像呈现的优势在于，从原始超声切面“提取”的器官表面能直接融入三维图像构建过程，无需进一步的计算机处理。可以看出，换能器头部的旋转代表了在临床环境中应用的切实可行的可能性。
