APPENDIX D
Gating Feature
ThegatingfeatureintheMR400outputsdataanddiscretesignalstotheMRIscannersystem
resultingfromthecollectionandprocessingofdatafromamonitoredparameter.Thescanner
systemusesthesesignalsanddatatopreciselycontrolthetimesthatitcollectsMRimagedata
fromthepatient.
Two
typesofdatacanbeoutputbythegatingfacilityoftheMR400:
•Analogwaveforms,whichareanalogelectronicrepresentationsofwaveformscollected
frommonitoredparameters;and,
•Gatingpulses,whicharediscreteelectronicsignalsthatindicatethatsomephysiological
eventassociatedwithamonitoredparameterhasoccurred.
MR400 Preparation for Gating
WhenpreparingtheMR400forgatingoftheMRsystem,ensurethatthecorrecttypeofgating
cableisconnectedbetweentherearpaneloftheMR400and theMRsystem.

Gating Connector Pin-outs
GatingsignalsfromtheMR400areavailablethroughtheshieldedgatingconnectorlocatedon
therearpanelofthecart(seeabove).Connectionsaremadeusingagatingcable.Gatingcables
areavailableforeachmanufacturer’sMRIsystem(GEHorizonLX,SiemensHarmony,Siemens
1 Gating connector for connection of the gating cable to the MR system.
