CT Operating System and Applicantions Software.

2 Pre-LFC Checks and Information Gathering

Procedure

    Notice Image
    • caution
    • Potential for Loss of Patient Data.
    • This procedure will overwrite existing data.
    • Before performing this procedure, ensure that the Archive and Network Queues are empty of patient data. If they are not, DO NOT proceed until it can be verified that all patient data has been archived.
    Notice Image
    • notice
    • After each reboot during the software install process, an 'Unrecognized X-Ray Tube' message will be displayed (as shown in Tube Install Certification Tool - Screens), until the tube identity has been selected and 'Flash Download' has also been performed. The same “unrecognized x-ray tube” message will also be displayed on the CSD Homepage, until the ID and flash download are done.
  1. Confirm that a current system state backup media is on site. If unsure of the status of the system state, execute System State Save Restore procedure found in the software chapter of this manual. Save a system state backup to USB media.
    2. Notice Image
    • notice
    • Do NOT switch screens or run other programs while saving System State. Otherwise the GUI may “hang” while trying to close, and the System State will need to be saved again.
    Notice Image
    • notice
    • When performing Save/Restore System State, check to ensure there is no two or more USB storage devices (SSA Key or other mobile storage devices) plugged in Console/Tower at the same time which may result in incorrect data storage.
  2. Remove USB Flash Drive from the host computer before starting the OS Load of the LFC process.

    • (For for Scanners with GE Tubes) If the software is installed by a non-GE person or the GE field engineer does not have a service key, a GE Field Engineer is required On-Site within 30 days, to perform the verification portion of this procedure. This verification cannot be done by non-GE employees. If a GE Service employee is not currently on site, please contact your GE Healthcare representative to arrange a visit. This section is absolutely critical to perform. Failure to do so will result in nuisance pop-ups to the customer, tube performance may decrease and certain scanner features may not be usable. Follow the procedure shown in the Flowchart below.
  1. Verification that a tube is a GE Healthcare tube (called “GE Tube” in the TIC tool) can be done by visually checking the Manufacturer Name, which can be found on the tube rating plate.

    • If you are installing a GE brand tube, click [GE Medial System Tube]

    • If rating plate does not identify the tube as a GE brand tube, click [ALL OTHERS]

      note: Some Advanced features may be disabled and pop-up warnings will be activated.
      note: Do not double-click the Tube Certification Tool. This will cause more than one tool window to be displayed; one with message ‘service key information not available’. If this happens, close the window and try again. If this happens more than once, reboot system and try again.

    Figure 20. Selection of Tube Identify

    Flowchart Note:

    Possible pop-up messages at start-up:

    • If the tube selection is GE tube without time limit, no pop-up messages relating to tube identity on boot up.

    • If the tube selection is GE with time limit, a message with days remaining for GE FE to verify tube will be shown on boot up until GE FE removes the time limit with service key. If not verified by GE FE within the time limit, the system will default to 'All Others'.

    • If the tube is set to 'All Others', unrecognized x-ray tube installed message will always be shown at boot up.

    Please refer to Tube Install Certification for examples of the screens displayed by the Tube Install Certification Tool.
