Flow analysis with digital subtraction angiography: 1. Description of a simplified flow model

JR Hesselink, KH Chang, KJ Chung and L Abbate

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.
