For Discovery MR450, Optima MR450w, and HD, the following coil configuration names must be installed to run this tool: GE_HDx 8CTL12, GE_HDx 8CTL23, GE_HDx 8CTL34, GE_HDx 8CTL45, and GE_HDx 8CTL56. For HDx legacy connectors, the following coil configuration names must be installed to run this tool: GE_8CTL12, GE_8CTL23, GE_8CTL34, GE_8CTL45, and GE_8CTL56.	-	-

note:

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

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
Place the phantoms between Posterior and Anterior parts of the coil as shown in Figure 2.

Figure 2. Positioning Phantom
Landmark on the coil crosshairs as shown in Figure 3.

Figure 3. Landmarking Coil
Perform the MCQA Test if available, otherwise perform the Surface Coils SNR Test.

Place the coil on the patient table and latch it to the table.
Place the TL unified phantoms on the center of the TL section of the coil as shown in Figure 4.

Figure 4. TL Unified Phantoms on Center
Align the phantoms to the center in S/I and R/L directions as shown in Figure 5 and Figure 6.

Figure 5. Alignment in S/I

Figure 6. Alignment in R/L
Place the large cylindrical unified phantom on the CT section and fix the C-Spine Bridge to the hooks provided as shown Figure 7.

Figure 7. Secure the Large Cylindrical Unified Phantom
Adjust the large cylindrical unified phantom such that it is in complete contact with the TL unified phantom (see Figure 8).

Figure 8. Adjust the Large Cylindrical Phantom
Adjust TL unified phantoms such that both the phantoms are in complete contact with each other as shown in Figure 9.

Figure 9. Adjust the TL Unified Phantoms
Connect the coil to Port A of the system LPCA.
Landmark the coil at the cross mark line on the C-Spine Bridge (see Figure 10) and advance to scan.
