For HDx, HDxt, and HDe, install the following coil configuration names to run this tool: `HDBreastServ`, `HDBreastRtServ`, and `HDBreastLtServe`.	-	-
For Discovery MR450 and Optima MR450w, use the following pre-installed coil configuration names to run this tool: `HDBreastRight` and `HDBreastLeft`.	-	-

Follow this procedure to prepare for the automated SNR test using the 1.5T HD Vibrant Breast Array Coil, GE/USAI catalog number M3087JG or M7000FZ.

Note:

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

Place the coil on the patient table, and insert the phantom positioner into the coil as shown below.

Figure 1. Phantom Positioner Inserted in Coil

The position of the spherical phantoms from the side of the coil is shown below.

Figure 2. Position of Spherical Phantoms
Place the phantoms on the phantom positioner as shown below, connect the coil to Port A of the LPCA, landmark on the center of the bridge between both chambers, and Advance to Scan.

Perform MCQA Test, if available. Otherwise, perform Surface Coils SNR Test.

No finalization steps.
