About this task

Follow this process to prepare for the automated SNR test using the1.5T 3ch Shoulder Coil with P connector by GE, catalog M7001NE.

Procedure

  1. Insert the Flat Filler Panel into the magnet end of the table.
    Figure 1. Flat Filler Panel
  2. Place the phantom positioner on the table, place coil on it, and connect the coil cable to P2 port.
    Note:
    If the phantom positioner (2375136-3) is newly orderd as FRU, remove the extra parts at the bottom and make the bottom plate flat.
    Figure 2. Remove bottom parts
    Note:

    Assemble the phantom positioner per following steps.

    1. Assemble the two tall large diameter posts (with small diameter posts on top) to the phantom positioning plate using the brass screws provided. The two tall large diameter posts will fit into the two large diameter pockets at the head end of the plate.

    2. Assemble the three small diameter posts (with angled top) to the phantom positioning plate using the brass screws provided. These three posts have the mounting holes offset from the center of the rod so they can only be assembled in the three holes in the plate that have the corresponding offset mounting holes.

    3. Assemble the short large diameter post (with small diameter posts on top) to the phantom positioning plate using the brass screws provided. The short large diameter post fits into the remaining pockets in the center of the positioning plate.

  3. Insert the phantom into the coil, then guide the coil onto the phantom positioner pins (the holes in the coil frame will accept the positioner pins).
