Follow this process to set up for the automated MCQA or SNR test using the 3.0T HD Cardiac Array by GE/USAI (M3334TS) .

Note:

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

Position the posterior coil component on the system table. Ensure that the Velcro straps hang free on either side of the table.

Figure 1. Posterior Coil Component Placement
Position the bottom phantom positioner on top of the posterior coil component.

Figure 2. Bottom Phantom Positioner Placement
Insert the phantom into the positioner.

Note:
Low SNR could result if phantom is incorrectly placed.

Figure 3. Positioning Phantom
Place the anterior phantom positioner as shown below.

Figure 4. Placement of Anterior Phantom Positioner
Place the anterior portion of the coil over the phantom positioner.

Figure 5. Placement of Anterior Coil
Secure with the Velcro straps.
Connect the coil to the system.
Move the table toward the bore, and landmark in the center of the anterior coil portion on the lines provided.

Figure 6. Landmarking Cardiac Coil
Proceed to the MCQA Test, if available. Otherwise, perform Surface Coils SNR Test.

Place the posterior section of the coil on the table.

Figure 7. Posterior Coil Component Placement
Place the TL unified phantoms over the posterior section so that the phantom is well centered in both the S/I and R/L directions.

Figure 8. Aligning TL Phantom in S/I Direction

Figure 9. Aligning TL Phantom in R/L Direction
Place the anterior section on the phantom set so that the coil is well centered in both the S/I and R/L directions with respect to the phantom. Fasten the Velcro straps so that the coil firmly snugs the phantom.

Figure 10. Placement of Anterior Section
Connect the coil to the appropriate port of the system LPCA.
Landmark the coil at the cross mark, and press advance to scan.

Note:
Make sure to align the markings to keep the posterior aligned with the anterior part of the coil.

Figure 11. Landmark Coil
Proceed to the MCQA Test, if available. Otherwise, perform Surface Coils SNR Test.
