Grandview Blvd. -W440 Waukesha, WI 53188, USA  \n\u003C Date of Letter Deployment> GEHC Ref\\# 26864  \nTo: Hospital Administrators / Risk Managers  \nManagers of Radiology/Cardiology  \nRadiologist/Cardiologist  \nChairman Medical Board  \nRelevant Head of Departments for hospital  \nRE: GE Healthcare Revolution EVO, Optima CT660 and Optima CT680 CT SmartPrep function issue  \nPlease ensure that all potential users in your facility are made aware of this notification and the recommended actions.  \nIssue GE Healthcare has become aware of a potential issue on Revolution EVO, Optima  \nCT660 and Optima CT680 CT Systems that could cause additional radiation exposure during use of the SmartPrep feature.  \nIf the system software options are loaded improperly, the system may not transition from the monitor to diagnostic scan phase when the selected Houndsfield unit (HU) trigger value is reached during a SmartPrep procedure. This can result in additional monitoring scans to be performed and may require rescan of the patient. Both of these situations result in additional X-ray radiation exposure to the patient.  \nInstructions You can continue using your system.  \nUntil GE Healthcare can check your system, the following workaround is  \nrecommended:  \n• Monitor the HU level during SmartPrep scans.  \n• Should the trigger not execute when the desired HU level is reached, manually initiate the diagnostic scan.  \nAffected Product Details  \n• Revolution EVO (certain software versions-see appendix)  \n• Optima CT660 (certain software versions-see appendix)  \n• Optima CT680 (certain software versions-see appendix)  \nYou are being contacted because you have been identified as an owner of one or more of these systems.  \nProduct Correction If your system is affected by this issue and requires software options reloading, a GE Healthcare Service Engineer will, without charge, correct your system by reloading the software options.  \nIn addition, your service provider should update their Service Manuals with the latest version as described below, in order to prevent the issue from happening in the future.  \nThe latest versions of the Service Manuals are available on the Internet:  \n1. Open an internet browser.  \n2. Enter URL: [http://www3.gehealthcare.com/en/Global_Gateway](http://www3.gehealthcare.com/en/Global_Gateway).  \n3.
