The following coil configuration names must be installed to run this tool: Check the system coil configuration for GP Flex coil configuration. If GP flex has not been installed, select GP flex from the list of available coils, and install.	-	-

Follow this process to prepare for the SNR test using the GP Flex coil.

The Quad Head Coil must be completely removed from the cradle before performing any body or surface coil scans. Failure to do this may result in damage to the Quad Head Coil T/R network.
Set the phantom and GP Flex coil on the cradle as following steps.
1. Align center of the mesh window and center of the cradle.
  
  Note:
  Place the GP Flex coil far enough from LPCA so that the coil cable won't be placed under the coil to avoid the low SNR.

2. Place the phantom with holder on S-I center of the GP Flex.
