Abstract

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‐ducibilities of pulsatile waveforms were <0.4 mL/sec (1 standard deviation). Increased response times due to the lengths of tubing required in MR flow experiments were surmounted by using a modified tubing configuration and pre‐compensated waveforms. Piston reversal was found not to cause major difficulties in MR flow experiments.
