  • Patent number: 7991451
    Abstract: A method of operation for a magnetic resonance imaging suite. A power supply of magnetic resonance injector system receives electrical power from an AC power outlet, both of which are located outside of a shielded room of the magnetic resonance imaging suite. Electrical power from the power supply of the magnetic resonance injector system is conveyed (via an appropriate power connection) into the shielded room of the magnetic resonance imaging suite and to a component (e.g., a power head) of the magnetic resonance injector system located inside the shielded room. While this electrical power is being conveyed, radio frequency energy emitted from the power connection is being filtered.
    Type: Grant

    Date of Patent: August 2, 2011
    Assignee: Liebel-Flarsheim Co.

  • Publication number: 20050027238
    Abstract: A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.
