Abstract

Fluid dynamic studies are carried out in order to develop a clinical digital subtraction angiographic (DSA) technique for measuring blood flow in coronary vessels. The authors investigated the bolus injection rate and vessel geometry on DSA measurements of coronary vessel models. The results show that interframe velocity measurements of the bolus wavefront differ from the actual velocities of saline. The standard deviations of the measured DSA velocities were 0. 290 to 0. 674 cm/frame for a saline velocity range of 0 to 1. 696 cm/frame.
