About this task

This procedure will setup for the automated MCQA test using the 3.0T HD 8-Channel Torso Coil by GE/USAI catalog M3335LN.

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 phantoms and phantoms positioner in the coil as shown in Figure 2:
    Figure 2. Positioning Phantom and Positioner
  3. Establish an axial landmark on the line on top of the coil. Advance to scan. See Figure 3.

Unified Phantom Setup

Procedure

  1. Note:

    Connect the coil to the system as shown in Step 1.

    Place the posterior section of the coil on the table as shown in Figure 4.
    Figure 4. Placing the Posterior Section of the Coil
  2. Place the positioner (2381683-4) of Torso into gaps present on the posterior section of the coil as shown in Figure 5.
