  • Galileo Positioning System (GPS) FAQs

  • What is a GPS?

    The Galileo Positioning System (GPS) is a mobile device that is used for Total Hip Arthroplasty (THA) for both Posterior and Anterior Approach, which helps the surgeon ensure proper implant fit. A built-in PACS streams pre-op X-rays from private practice and send intra-op X-rays back to central PACS.  Battery power allows for device to be moved from room to room efficiently. The GPS has dual monitors for viewing pre-op and intra-op images.

    The Posterior Approach obtains an image in 6 seconds using a wireless DR Panel.  The Surgeon’s Checklist® provides the capability to perform measurements such as cup abduction angle and cup anteversion angle, automatically prompts patient rotation correction suggestions, and measure limb length and offset.

    For Anterior Approach procedures, the unit connects to any C-Arm.  The Surgeon’s Checklist® provides Radiographic ellipse overlay for inclination and anteversion angles.  Digital overlay of pre-op and intra-op limbs for LLD and offset verification.  Illoischial line to tear drop angle allows for accurate inclination.  Surgeons Checklist® auto detects bony landmarks.

    The GPS can have the Posterior option only, the Anterior option only or both on one GPS.

    What are the components of the GPS?

    The GPS consists of a cart which contains a UPS (uninterruptible power supply), Solid State Computer, Dual 24” Monitors, Isolation transformer and Wireless Adapter.

    The Posterior option has a Wireless DR Panel, Bucky with Grid and Router or System Control Unit.

    The Anterior Approach option has a Frame Grabber and BNC Converter with BNC cable (Connects to C-Arm).

    How do I schedule a Demo of the GPS?

    What applications does the GPS support?

    Currently Total Hip and Knee are supported.  Other applications are being implemented such as Trauma, Spine, Shoulder, etc.  Contact Radlink or your local DePuy Synthes sales representative.

    What Operating System does the Computer run?

    Windows7 64-Bit.

    How do I power the GPS on?

    Connect the Power cord to the wall receptacle.  All components (UPS, Monitors, Isolation Transformer, Router/System Control Unit) except the computer will power on.  Turn on the computer via the power button.

    How do I power the GPS off?

    The GPS should be shut down by selecting “Shut Down” from the Windows Task Bar.  Once the computer has completely shut down the power can be disconnected from the wall receptacle.  Failure to shut the GPS down properly will result in the Raid rebuilding which was cause the system to respond slowly.  Improper shut downs can also cause corruption to the Windows O/S and installed software.

    How do I burn a CD?

    Be certain the study has been completed.  The study is completed by selecting “Complete Study” at the top of the Worklist page with the study open.  From the Worklist (Select Study) if the patient study does not appear in the Worklist you will need to search for the study using the patient name or ID.  Select “Burn CD” at the top of the Worklist.  In the far left column highlight the patient(s) study or studies that you want to burn to CD.  Select “Burn” at the bottom right corner.   Note:  You can select multiple studies by holding the “Ctrl” key and clicking in the far left column.

    Why is the GPS Beeping?

    The GPS has a UPS (Uninterruptable Power Supply).  If it is unplugged from an outlet it will beep while it is on battery power.  The UPS should be plugged into an outlet due to battery life is limited.  It will get power from the power source.  Note:  When the UPS is unplugged from the wall receptacle it should be turned off.  There will be no lights illuminated.

    Can I import pre-op images from other sources to the GPS for viewing during the procedure?

    DICOM 3.0 Compliant Images from other sources can be imported into the GPS System.  There is an icon on the Pre-Op Desktop (Top Monitor) labeled “Shortcut Incoming”.  Insert your CD or Flash drive into the GPS Computer.  Copy the DICOM files only to the incoming folder on the Pre-Op Desktop.  The images will appear when the Radlink Pro Imaging is opened.
