Computer-controlled flow simulator for MR flow studies
A novel computer‐controlled flow simulator for use in magnetic resonance (MR) flow experiments was evaluated. The accuracy in constant‐flow mode was better than 1%. The accuracy in pulsatile‐flow mode was found to be dependent on the interconnecting tubing. The short‐term and long‐term repro‐ducibil...
