Warning

All RF coil-related tests must be run on a system that is well calibrated and passes all system tests. The system should have passed Install In Spec (IIS), especially white pixel, correlated noise, and Multi-Coil Receive (MCR) tool.

This coil configuration name must be installed to run the SNR test tool: HD Foot Ankle. Install this coil configuration with Config File Manager.	-	-

About this task

This procedure can be performed using either a flat table or a curved table.

Note:

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

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

(For flat table) Insert the curved adapter panel into the magnet end of the table.

(For curved table) Place the small cylindrical unified phantom horizontally on the baseplate.

Figure 4. Cylindrical Unified Phantom on Baseplate on Curved Table
Place the cubical unified phantom vertically. Secure the phantom to the baseplate using the Velcro strap.

Perform the Multi-Coil Quality Assurance Tool procedure.
After the test is complete, carefully remove the cubical phantom from the baseplate. Then carefully remove the cylindrical phantom. Avoid damage to the phantoms.
