An inexpensive, simplified flow model for use with digital subtraction angiographic (DSA) equipment is described. System tests show that the model gives reproducible data with a standard deviation of +/- 2.6%. Flow analysis also reveals an appropriate response to flow rates of 20-240 ml per min. The flow model can be used to investigate many of the variables and sources of error in DSA flow measurements.
本文描述了一种用于数字减影血管造影（DSA）设备的低成本、简化血流模型。系统测试表明，该模型能给出可重复的数据，标准偏差为±2.6%。血流分析还显示，该模型对每分钟20至240毫升的流速有适当的响应。该血流模型可用于研究DSA血流测量中的许多变量和误差来源。
