Abstract
A patient infusion and imaging system includes a magnetic resonance imaging (MRI) scan room shielded from electromagnetic interference and image acquisition equipment positioned within the MRI scan room. The system further includes an IV liquid infusion apparatus configured to be positioned at any location within the MRI scan room without introducing image-degrading RF interference and without being affected by magnetic fields produced by the magnetic source. The IV liquid infusion apparatus includes a pump disposed to receive a liquid conduit and to transfer IV liquid through the liquid conduit from a liquid IV container source, a non-magnetic ultrasonic motor, and a non-magnetic controller configured to selectively actuate the motor to drive the pump, and thereby transfer liquid from the IV container source through the liquid conduit at a controllable volumetric rate.
