Computer-controlled flow simulator for MR flow studies

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...

The accuracy in pulsatile‐flow mode was found to be dependent on the interconnecting tubing. The short‐term and long‐term repro‐ducibilities of pulsatile waveforms were
