  1. Note:
    The table adapter will need to be installed prior to completing the SNR Procedure. Place table adapter on coil and secure with five screws as indicated.
    Figure 1. Table Adapter
    Remove the Flat Filler Panel from the Table if present.
  2. Place the 48CH Head Coil posterior unit on the Table as shown. Connect the coil to the P2 Port on the table.
    Figure 2. Placement of 48CH Head Coil Posterior Unit
  3. Place the 48CH Head Coil Phantom Positioner (5756144) into the 48CH Head Coil posterior unit, then place the Large Cylindrical Unified Phantom and TL Unified Phantom into the 48CH Head Coil Phantom Positioner.
    Figure 3. Placement of Large Cylindrical and TL Unified Phantoms
    Note:

    Use the correct Phantom Positioner (5756144). Do not use the Phantom Positioner for the DV system and SIGNA Pioneer. Otherwise, it will affect the SNR result.
