  2. If any of these items are missing, contact Varian at 1-888-VARIAN5.

    Figure 1. RPM Respiratory Gating Kit

2.2 Typical and Alternate Configurations

Procedure

  1. (For Typical Gating system installed in Control Room) The respiratory trigger cable is part of the system installation cable set and has been installed in the cable trough or conduit between the Scan Room and Control Room during the system installation process to accommodate a typical Control Room respiratory gating system installation.
  2. (For Alternate Gating system installed in Scan Room) Some customers may have existing Respiratory systems and may still use the alternate cable 5212250. If the customer prefers an “In Scan Room” installation (Gating system located near the gantry) then cable 5199717 will not be used and the gating system will be directly connected to the Accessories Panel on the side of the gantry with this existing alternate cable 5212250.
  3. (For Previously Installed Respiratory System) If the customer has previously purchased a Respiratory system and this Respiratory system is being re-installed as part of a system installation, cable 5174616, 5212250, or 5263547 may be present on site.

    • If the respiratory gating computer system is located in the Control Room, remove and discard cable 5174616, 5212250, or 5263547 from the cable trough/conduit between the Scan Room and Control Room and use 5199717, which is part of the system cable collector.

    • If the respiratory gating computer system is located in the Scan Room and cable 5174616 is being used, discard this cable and replace it with 5212250 or 5212250-2 refer to Table 1 for desired cable length.

    • If the respiratory gating computer system is located in the Scan Room and cable 5212250 or 5212250-2 is currently on site, cable 5199717 will be unused (located in the cable trough/conduit between Scan Room and Control Room). The customer may continue to use cable 5212250 or 5212250-2.

    • If the respiratory gating computer system is located in the Scan Room and the customer prefers a shorter cable, replace cable 5212250 with 5212250-2 Table 5.

  4. Varian Camera Mounting Configurations:

    • PET System ONLY: If the RPM (Remote Patient Monitoring) camera is to be mounted to the cradle using the Varian Camera Mount Bracket kit Catalog # E8819HB, this bracket must be installed prior to starting this procedure. Refer to the installation instructions included with that option.

    • If the RPM (Remote Patient Monitoring) camera is to be installed on the table cradle using one of the Flat Top Table Option kits then this option must be installed prior to starting this procedure. Refer to the installation instructions included with that option.

    • All other camera mount configurations must be coordinated with the customer on a case-by-case basis and may require a structural Engineer. These may include wall mounts, ceiling mounts etc. For a successful installation, clarify the mounting configuration before proceeding with this procedure.
