The prerequisite for the safe performance of an intracoronary intervention is an optimal angiographic visualization. This includes high resolution film and video equipment and the acquisition of spatial information about anatomic details during the procedure. The geometric properties of modern biplane multidirectional X-ray equipment allow for exact spatial computations. These can be used for optimal portraying of coronary segments by computed triple orthogonal projections. In addition, an improvement in quantitative angiography is possible by calculation of the exact radiological magnification factor of coronary stenosis.
冠状动脉介入手术安全实施的前提是获得最佳的血管造影图像。这包括高分辨率的胶片和视频设备，以及在手术过程中获取有关解剖细节的空间信息。现代双平面多向X射线设备的几何特性允许进行精确的空间计算。这些计算可用于通过计算机三维正交投影对冠状动脉节段进行最佳描绘。此外，通过计算冠状动脉狭窄的精确放射放大倍数，定量血管造影也可以得到改进。
