About this task

Follow this process to prepare for the automated SNR test using the 1.5T HD Body Array Coil by GE/USAI (M3335MC).

Note:

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

Legacy Phantom Procedure

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 a phantom between Posterior and Anterior parts of the coil as shown in Figure 2.
    Figure 2. Positioning Phantom
  3. Secure the coil over the phantom by strips as it shown in Figure 3.
    Figure 3. Securing Coil Over Phantom
  4. Landmark the coil at the indicated line (arrows) as shown in Figure 4.
    Figure 4. Landmarking the Coil
  5. Perform the MCQA Test if it is available, otherwise perform the SNR Test.

Unified Phantom Procedure

Procedure

  1. Place the posterior section of the coil on the table. See Figure 5.
    Figure 5. Posterior Section of Coil on Table
  2. Place the TL unified phantoms over the posterior section as in Figure 5 such that the TL unified phantoms are well centered on both S/I directions as shown in Figure 6 and R/L direction as shown in Figure 7.
    Figure 6. Phantom Posterior Aligned on S/I Direction
    Figure 7. Phantom Posterior Aligned on R/L Direction
  3. Place the anterior section on the TL unified phantoms such that the coil is well centered in both S/I and R/L directions with respect to the phantom set as shown in Figure 8 and Figure 9.
    Figure 8. Phantom Anterior Aligned on S/I Direction
    Figure 9. Phantom Anterior Aligned on R/L Direction
  4. Fasten the Velcro straps so that the coil firmly snugs the phantoms.
  5. Connect the coil to Port A of the system LPCA.
  6. Landmark the coil at the center cross mark as shown in Figure 10 and advance to scan.
