Abstract
The accuracies of measurement of the velocity field using clinical and research magnetic resonance scanners were compared. The flow velocity was measured for a fluid simulating blood in the carotid artery model connected to a programmable pump. Using phase-contrast magnetic resonance tomography, velocity distributions in the carotid artery model and were obtained and compared with the analytical solution for viscous liquid flow in a cylindrical tube (Poiseuille flow). It is established that the accuracy of the velocity measurement does not depend on the field induction and spatial resolution of the scanners.
