Recent developments in magnetic resonance (MR) allow high resolution imaging of flowing blood. To overcome the tomographic nature of conventional MR acquisitions, projection angiograms can be produced. These angiograms are similar in their display of blood vessels to plain film or digital subtraction angiograms. However, the three-dimensional information inherent in them is partly lost when single projections are viewed. We describe a method of three-dimensional display consisting of stereo pairs of the MR angiograms. With these an examiner experienced in stereo viewing can recover depth perception.
磁共振（MR）技术的最新进展使得对流动血液进行高分辨率成像成为可能。为了克服传统MR采集的断层特性，可以生成投影血管造影。这些血管造影在血管显示方面与平片或数字减影血管造影相似。然而，当查看单个投影时，其中固有的三维信息会部分丢失。我们描述了一种由MR血管造影的立体对组成的三维显示方法。通过这些，有立体视觉经验的检查者可以恢复深度感知。
