DSA is an imaging technique that should be integrated into a state-of-the-art angiographic system for proper application and utilization. This results in improvements in both efficiency and diagnostic accuracy. However, from the physician's viewpoint, the proper use of a DSA imaging facility mandates not only an understanding of angiographic principles as applied with conventional film-screen systems but also an in-depth understanding of the factors that affect DSA performance. In particular, factors affecting spatial resolution and contrast sensitivity are crucial. This knowledge has to be applied interactively and "on-line" to achieve optimal IA-DSA image quality.
数字减影血管造影（DSA）是一种成像技术，应集成到先进的血管造影系统中以便正确应用和使用。这会提高效率和诊断准确性。然而，从医生的角度来看，正确使用DSA成像设备不仅需要理解传统胶片-增感屏系统所应用的血管造影原理，还需要深入了解影响DSA性能的因素。特别是，影响空间分辨率和对比敏感度的因素至关重要。必须交互式且“在线”应用这些知识，以实现最佳的IA-DSA图像质量。
