Unified Phantom Setup

About this task

Follow this process to prepare for the automated SNR test using the 3.0T HD 8-channel foot/ankle coil by Invivo (M3340CB).

Procedure

Place the foot/ankle coil baseplate on the table.

Figure 5. Foot/Ankle Coil Baseplate on Table
Place the small cylindrical unified phantom horizontally on the baseplate.

Figure 6. Cylindrical Unified Phantom on Baseplate
Place the cubical unified phantom vertically, and fix the phantom to the baseplate using the Velcro.

Figure 7. Cubical Unified Phantom on Baseplate
Cover the baseplate with the coil.

Figure 8. Coil over Baseplate
Connect the foot/ankle coil to port A of the LPCA, and landmark the coil at the crossmark on the coil handle.

Advance to scan.
Perform the Multi-Coil Quality Assurance Tool procedure.
After the test is completed, carefully remove the cubical phantom out of the baseplate, then remove the cylindrical phantom. Avoid damage to the phantoms.
