    A scanner and EchoPAC PC in a direct 
    connect environment
    In this scenario the data is transferred from the Vivid 7/
    Vivid 7 PRO to a dedicated EchoPAC PC workstation over the 
    Ethernet (either in a peer-to-peer connection or with a 
    crossover cable, or in a network). The database from the 
    EchoPAC PC is used as the master and images are stored 
    directly to the EchoPAC PC internal harddrive. In this 
    configuration the scanner is just an intermediate acquisition 
    unit which after completion of a study, will not contain any 
    patient information, measurements or images.
     Figure 8-23: A scanner and EchoPAC PC in a direct connect 
    environment (pier to pier or network)
    The acquisition can be done online or offline. Both situations 
    are described below.
    Direct connect with online acquisition
    Scanner’s dataflow configuration
    1. Select the RemoteArch-RemoteHD dataflow as default 
    dataflow in the sublevel Dataflow in the subgroup 
    Connectivity of the Configuration management package 
    (see page 424 and following pages).
    When saving the study on the scanner, the images are 
    transferred from the scanner’s image buffer to the 
    harddrive of the EchoPAC PC. Patient demographics, 
    measurements and reports are transferred on the fly when 
    entering the information on the Vivid 7/Vivid 7 PRO.

    Review on the EchoPAC PC workstation
    1. Select the LocalArchive-Int.HD dataflow on the EchoPAC 
    PC (can be configured as default dataflow).
    2. Press Archive and select the patient to be reviewed.
    Backup
    Patient and report archives, presets and templates
    1. Perform a backup on a weekly basis on a dedicated MOD 
    using the Backup function as described in the workstation 
    user manual.
    Images
    1. Move images on a weekly basis from the internal harddrive 
    of the EchoPAC PC to a dedicated MOD as described in 
    ’Backup procedure’ on page 329.
    Direct connect with offline acquisition
    If going offline the archive from the EchoPAC PC must be 
    exported to the scanner prior disconnection as follow.
    Copy of the EchoPAC PC archive prior offline acquisition
    1. Make sure there are no studies on the internal harddrive of 
    the scanner (dataflow LocalArchive-Int.HD) that have not 
    been copied to the EchoPAC PC. If so use the Export/
    import procedure (see page 315) to copy them prior to 
    proceeding.
    While connected, export from LocalArchive-Int.HD 
    (scanner) to Remote Archive-Remote Storage.
    Make sure that the option Copy images is checked.
    CAUTIONDo NOT open a study on the EchoPAC PC workstation before the 
    study is closed on the scanner.
    CAUTIONKeep a manual log of disk labels.

    2. Export the data (demographics, measurements and report) 
    from EchoPAC PC to the scanner.
    Export from EchoPAC PC LocalArchive-Int.HD to 
    RemoteArch-RemoteHD.
    Scanner’s dataflow configuration for offline acquisition
    1. When offline, select the LocalArchive-IntHD dataflow.
    The local database is used for patient archiving. Images 
    are stored to internal harddrive.
    Export examinations done offline from the scanner to 
    EchoPAC PC
    1. When reconnected, export the data (images, 
    demographics, measurements and report) for the 
    examination(s) done offline to EchoPAC PC as describes in 
    ’Export/Import patient records/examinations’ on page 315.
    Press Today to dis-
    play today’s exams 
    to ease the search.Export from LocalArchive-Int.HD to RemoteArch-
    RemoteHD.
    Make sure that the option Copy images is checked.
    To free space in the internal harddrive on the scanner, 
    check the command Delete selected patient(s) after 
    copy in the Export patient window (see Figure 8-28, 
    page 317).
    The examination done offline can now be reviewed on the 
    workstation.
    CAUTIONRestore ONLY the patient and report archives, NOT the system 
    and user defined configurations.

    A scanner and a DICOM ser ver in a 
    network
    In this scenario the Vivid 7/Vivid 7 PRO is configured to work 
    with a DICOM server in a network environment. Images are 
    first saved on the local image buffer on the scanner. At the end 
    of the examination the images are sent to the DICOM server 
    via a DICOM spooler.
    This scenario requires that the scanner is configured to be 
    connected to the DICOM server as described below.
    Scanner configuration
    To work against the DICOM server the following information 
    has to be entered in the scanner:
    •  The DICOM server IP address, subnet mask and eventually 
    the gateway
    •  The DICOM server port number
    •  The DICOM server AE title (the server’s name)
    •  The scanner IP address
    In addition the AE Title of the scanner may have to be entered 
    in the DICOM server setup.
    TCPIP setting on the scanner
    1. Enter the DICOM server IP address, subnet mask and 
    eventually the default gateway in the TCPIP sublevel 
    window (IP settings field) in the configuration management 
    package of the Vivid 7/Vivid 7 PRO ultrasound unit (see 
    ’TCP/IP’ on page 442).
    Setup of the DICOM server in the scanner’s configuration 
    management package
    1. In the scanner’s configuration package select the sublevel 
    CAUTIONDo NOT change the Remote archive setup in TCPIP sublevel.

    Expor t/Impor t patient records/examinations
    Patient records/examinations from the local archive on one 
    system (Vivid 7 or EchoPAC PC) can be exported to the local 
    archive on another system via a formatted Magneto Optical 
    (MO) disk or CD-R. Patient records/examinations from the local 
    archive can also be exported directly to a remote archive (Echo 
    server, DICOM server or EchoPAC PC depending on the 
    environment). In addition patient records/examinations from a 
    remote archive (Echo server or EchoPAC PC depending on the 
    environment) can be exported to a removable media or to a 
    DICOM server. Database information (patient and report 
    archives) can be exported with or without images. No data is 
    deleted from the source archive when exporting data unless 
    the command Delete selected patient(s) after copy is 
    checked in the Export patient window (see Figure 8-28, 
    page 317).
    Similarly, patient records/examinations from the local archive 
    on one system can be imported to the local archive on another 
    system via a formatted MO disk or CD-R. Database information 
    can be imported with or without images. No data is deleted 
    from the source archive when importing data. In addition 
    patient records from a removable archive can be imported to a 
    remote archive (Echo server).
    Expor ting patient records/examinations
    1. Insert a blank formatted (see page 435) removable media 
    in the drive.
    2. Press 
    ARCHIVE on the Front panel.
    The Search/Create Patient window is displayed (Figure 8-
    7, page 280).
    3. Select the source archive in the Dataflow field:
    • LocalArchive-Int.HD: exports data from the local 
    archive.
    • RemoteArch-RemoteHD: exports data from an Echo 
    server.
    4. Press Export in the Search/Create Patient window.
    The Export dialogue window is displayed.

    5. Select one of the following destinations from the 
    Destination drop-down menu:
    • Removable MOD Archive: exports raw and DICOM (if 
    present) data to a removable MOD.
    • Pure DICOM MOD525: export DICOM data only to a 
    removable MOD.
    • Removable CD Archive: exports raw and DICOM (if 
    present) data to a CD-R.
    • Pure DICOM CD-R: export DICOM data only to a CD-R.
    • Remote Import/Export Archive: exports raw and 
    DICOM (if present) data to an Echo server (network) or 
    EchoPAC PC (direct connect or network).
    • Pure DICOM Storage: exports DICOM data only to a 
    DICOM server.
    • Excel file: exports data to a spreadsheet. The excel file 
    is stored in the location defined in the Sublevel Tools in 
    the Configuration package (see page 435).
    • HL7: exports examination results to the “Vivid HL7 
    Gateway”, which “feeds” the results to HIS through HL7 
    protocol. M&A and diagnosis-codes are stored as an 
    Excel file, reports are stored as CHM-files.
    The file path to the shared volume on “Vivid HL7 
    Gateway” must be pre-configured in the Sublevel Tools 
    in the Configuration package (see page 435). 
    • DICOM Print: prints images to a DICOM printer via 
    DICOM spooler.
