For HDx, HDxt, and HDe, the following coil configuration name must be installed to run this tool: HDWRIST.	-	-
For MR450, MR450w and MR450w GEM, the following coil configuration name must be installed to run this tool: GE_HDx Wrist.	-	-

Follow this process to prepare for the MCQA test using the 1.5T HD 8-Channel Wrist Array by Invivo, Catalog Number M3335LJ (curved base).

note:

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

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

Place the baseplate on the table as shown.
