note:

Coils do not ship with phantoms. Phantoms come in a unified phantom set with the MR system.

Legacy Phantom Setup

Procedure

  1. note:

    If installing the coil for the first time in a system, please refer to Auto Coil Install.

    Position the coil in the cradle, connect the cable as shown in Figure 1 .

    Figure 1. Connecting The Coil

  2. Place the phantoms between Posterior and Anterior parts of the coil as shown in Figure 2.

    Figure 2. Positioning Phantom

  3. Landmark on the coil crosshairs as shown in Figure 3.

    Figure 3. Landmarking Coil

  4. Perform the MCQA Test if available, otherwise perform the Surface Coils SNR Test.

Unified Phantom Setup

Procedure

  1. Place the coil on the patient table and latch it to the table.
  2. Place the TL unified phantoms on the center of the TL section of the coil as shown in Figure 4.

    Figure 4. TL Unified Phantoms on Center

  3. Align the phantoms to the center in S/I and R/L directions as shown in Figure 5 and Figure 6.

  4. Place the large cylindrical unified phantom on the CT section and fix the C-Spine Bridge to the hooks provided as shown Figure 7.

    Figure 7. Secure the Large Cylindrical Unified Phantom

  5. Adjust the large cylindrical unified phantom such that it is in complete contact with the TL unified phantom (see Figure 8).

    Figure 8. Adjust the Large Cylindrical Phantom

  6. Adjust TL unified phantoms such that both the phantoms are in complete contact with each other as shown in Figure 9.

    Figure 9. Adjust the TL Unified Phantoms

  7. Connect the coil to Port A of the system LPCA.
  8. Landmark the coil at the cross mark line on the C-Spine Bridge (see Figure 10) and advance to scan.
