For Discovery MR450 and Optima MR450w, the following coil configuration names must be installed to run this tool: 8NVHEAD_A and 8NVARRAY_A. For HDx, HDxt, and HDe, the following coil configuration names must be installed to run this tool: 8NVHEAD_A and 8NVARRAY_A.	-	-

Follow this process to prepare for the automated SNR Test using the 1.5T 8-Channel Neurovascular Array Coil by Invivo (M3335M).

note:

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

note:
If installing the coil for the first time in a system, refer to Auto Coil Install.

End the previous exam if not already done.
Make a note of the serial number of the coil.
Remove the top of the coil, and secure the base of the Invivo HD 1.5T 8-Channel Neurovascular Array to the cradle in the same position (shown in Figure 1) as the standard head coil.

Figure 1. Coil Bottom on Cradle
Place the phantom positioner on the coil as shown in Figure 2.

note:
For correct bottle placement, fully insert the bottom of each phantom bottle until it touches the curved inside surface of the main phantom. (See Figure 4.)

Figure 4. Correct Bottle Placement
Attach the top to the coil as shown in Figure 5.

Figure 5. Top on Coil
Perform the Multi-Coil Quality Assurance (MCQA) Tool if available, otherwise perform the Surface Coils SNR Test.

Place the base of the NV array coil on the patient table and latch it to the table as shown in Figure 6.
