Follow this process to prepare for the automated SNR test using the 12-Channel Single or Dual Connector Body Array Coil by GE/USAI.

Note:

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

Place the posterior section of the coil on the table. Place the TL unified phantoms over the posterior section as shown in Figure 1 such that the phantoms are well centered on both S/I direction as shown in Figure 2 and R/L direction as shown with arrows in Figure 3.

Figure 3. TL Unified Phantoms Centered on Posterior R/L Direction
Place the anterior section on the 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 the Figure 4 and Figure 5.

Fasten the Velcro straps so that the coil firmly snugs the phantoms.
Connect the coil to Port P of the system LPCA. Landmark the coil at the center cross mark as shown in the following illustration and advance to scan.

After coil and phantom are properly positioned, perform Multi-Coil Quality Assurance (MCQA) Tool.

No finalization steps.
