About this task

This procedure will set up for the automated MCQA test using the 3.0T HD 8-Channel CTL array by GE (M3335LM).

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 and connect the cable in Port A.
  2. Place phantoms on the coil as shown in Figure 1.
