The 1.5T GEM Coil MCQA will use the 1.5T phantoms, which are green in color. The 3.0T GEM Coil MCQA will use the 3.0T phantoms, which are pink in color. The Small Cylindrical Unified Phantom is green in color and for both 1.5T and 3.0T coils.

Note:

Coils do not ship with phantoms. Phantoms come in a Unified Phantom set with the MR System.

Procedure

  1. Place the Flat Filler Panel (shown below) on the GEM table.
    Figure 1. Flat Filler Panel
  2. Place the two TL Unified Phantoms on the GEM table, centering them right to left, and ensure the top edge (facing the bore) of the first phantom coincides with the edge of the Flat Filler Panel.
    Figure 2. Placement of TL Unified Phantoms
  3. Place the PV Coil on the Flat Filler Panel, making sure the edge of the PV Coil touches the edge of the TL Unified Phantom as shown.
    Figure 3. Edges of PV Coil and TL Unified Phantom
  4. Place the PA Phantom Positioner on top of the TL Unified Phantoms, fitting the alignment block on the PV Coil into the alignment notch on the PA Phantom Positioner as shown.
    Figure 4. Placement of PA Phantom Positioner
  5. Flip the PV Upper unit onto the PA Phantom Positioner, and fasten with Velcro® straps as shown.

  6. Place the Large and Small Unified Cylindrical Phantoms into the PV Phantom Positioner, and place the phantom assembly under the right side of the PV Coil.
    Note:

    Make sure the edge of the Large Unified Cylindrical Phantom is aligned with the edge of the TL Unified Phantom, and wrap the right portion of the PV Coil closely around the phantom assembly.

  7. Connect the PV Coil to Port P2 on the GEM table, landmark the coil in the middle of the latch (shown below) of the PV Coil, and press Advance to Scan.
    Figure 7. Latch on PV Coil
  8. Run the Multi-Coil Quality Assurance Tool. Ensure that the correct coil is selected in the Current Coil field: 1.5T_GEM_PV_Upper_Right (shown below) or 3.0T_GEM_PV_Upper_Right for a 3.0T system.
