Scan the phantom

About this task

The DAQA procedure provides a means for you to track overall system or RF coil functionality. The application supports all GE coils that have the coil ID feature.

Important: To obtain meaningful, reproducible data for a given RF coil, consistency and repeatability is key. Always use the same phantom, the same positioning of the phantom in the coil and the same landmark at the same location on the phantom/coil.

Phantom name
1.5T TLT Head Sphere (Green)
Body TLT Sphere Phantom
Body TLT Loader

Step-by-step instructions

Set up the desired coils and the phantom on the table. The coil and phantom you choose will depend on whether you are going to perform the SNR or System test.
1. Place the coil on top of the cradle and place the phantom holder and phantom inside the coil - in this example, the TDI Head Neck Array coil.

2. If you are using the body coil, use the Body TLT phantom and Loader. Follow the pictorial guidelines below to transport the phantom.

Press Advance to Scan.
From the Worklist Manager, click the to begin a scan.
In the New Patient area of the Worklist Manager, type geservice as the patient ID and 111 lbs (or 50 kg) as the patient weight.

Important: A higher weight than 50 kg for the phantom scan could cause system damage.
Click Show Protocols to open the Protocol screen.
Move a 3-plane localizer protocol from the Protocol list to the Multi-Protocol Basket and click Accept. For example, click Template > 3-Plane 2D Localizer > FGRE.
Click Start Exam.
Scan the 3-plane localizer.
When complete, click End Exam from the scan session tab.
Perform either the SNR test or System test.
