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.

Place the base of the NV array coil on the patient table and latch it to the table as shown in Figure 1.

Place the phantoms in the positioner as shown in Figure 3.

Figure 3. Phantoms in the Positioner
Carefully align the connector pins on the base of the coil with the top part of the coil and then latch both the coil sections into place as in Figure 4. (The scanner will not operate if the coil sections are not latched correctly).
