For HDe, HDx, and HDxt, the following coil configuration names must be installed to run this tool: HD BodyArray_serv, HD_BodyArrayLserv, and HD_BodyArrayRserv.	-	-
For Discovery MR450 and Optima MR450w, the following coil configuration names must be installed to run this tool: 8Ch Body Upper, and 8Ch Body Lower.	-	-

Follow this process to prepare for the automated SNR test using the 1.5T HD Body Array Coil by GE/USAI (M3335MC).

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 a phantom between Posterior and Anterior parts of the coil as shown in Figure 2.

Figure 2. Positioning Phantom
Secure the coil over the phantom by strips as it shown in Figure 3.

Figure 3. Securing Coil Over Phantom
Landmark the coil at the indicated line (arrows) as shown in Figure 4.

Figure 4. Landmarking the Coil
Perform the MCQA Test if it is available, otherwise perform the SNR Test.

Place the posterior section of the coil on the table. See Figure 5.

Figure 5. Posterior Section of Coil on Table
Place the TL unified phantoms over the posterior section as in Figure 5 such that the TL unified phantoms are well centered on both S/I directions as shown in Figure 6 and R/L direction as shown in Figure 7.

Figure 6. Phantom Posterior Aligned on S/I Direction

Figure 7. Phantom Posterior Aligned on R/L Direction
Place the anterior section on the TL unified phantoms such that the coil is well centered in both S/I and R/L directions with respect to the phantom set as shown in Figure 8 and Figure 9.

Figure 8. Phantom Anterior Aligned on S/I Direction

Figure 9. Phantom Anterior Aligned on R/L Direction
Fasten the Velcro straps so that the coil firmly snugs the phantoms.
Connect the coil to Port A of the system LPCA.
Landmark the coil at the center cross mark as shown in Figure 10 and advance to scan.
