Method of Operation for a Magnetic Resonance Imaging Suite

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.

1 . A method of operation for an MR injector system, the method comprising:
 a power supply of the injector system receiving AC power from an AC power outlet;   the power supply converting the AC power received to DC power;   conveying power from the power supply toward a battery compartment of the injector system;   filtering radio frequency energy from the power conveyed from the power supply toward the battery compartment of the injector system; and   conveying power from the battery compartment to a power head of the injector system.   
     
     
         2 . The method of  claim 1 , wherein the battery compartment is devoid of a battery during the conveying of power from the power supply toward the battery compartment. 
     
     
         3 . The method of  claim 1 , wherein the battery compartment is devoid of a battery during the conveying of power from the battery compartment to the power head. 
     
     
         4 . The method of  claim 1 , further comprising a power control that comprises the battery compartment. 
     
     
         5 . The method of  claim 1 , wherein the conveying of power from the power supply toward the battery compartment comprises the power being conveyed through a penetration panel of an MRI suite. 
     
     
         6 . The method of  claim 5 , wherein the filtering of radio frequency energy from the power conveyed from the power supply is accomplished at or near a penetration panel of an MRI suite. 
     
     
         7 . The method of  claim 6 , wherein the filtering occurs prior to the power being conveyed through the penetration panel. 
     
     
         8 . The method of  claim 5 , wherein the filtering comprises attenuating RF noise within a rejection frequency band selected to correspond to RF frequencies used by an MRI unit. 
     
     
         9 . The method of  claim 1 , further comprising:
 transmitting data signals from a control panel of the injector system to a power head of the injector system.   
     
     
         10 . The method of  claim 1 , further comprising:
 installing a syringe containing contrast media on the power head of the injector system, and   energizing said power head with power from the battery compartment to expel contrast media from said syringe.
