Replacing BRM RF Body Coil
Prerequisites
The RF body coil cartridge is a FRU that mounts inside the gradient coil (also a FRU), and is available in 1.0T and 1.5T versions. If the RF coil fails, it must be removed from the gradient coil and replaced with a new one. Since the replacement procedures for the RF and gradient coils are closely related, references are made below to the epoxy-filled gradient coil replacement procedure where the instructions for removal of like parts (for example, bridge removal) can be found. Although some tasks (such as connecting/disconnecting various cables, etc.) can be accomplished by one person, replacing a failed RF body coil requires three people.
1 Unpacking BRM RF Body Coil
A new RF body coil is packed in a cylindrical shipping container that is strapped inside a combination pallet and outer shipping box. It rests on a pair of installation tracks. The shipping container never leaves the box; the RF body coil is removed from this combination. Included are two extra installation tracks used in the gradient body coil to assist in the RF coil exchange.
Procedure
caution- Possible equipment damage!
- Due to the size and weight of the RF body coil, damage is possible when moving it in or out of the shipping container.
- Three (3) people are required to perform this task.

- Possible equipment damage!
- Due to the size and weight of the RF body coil, damage to the coil or the RF shielding is possible when moving the coil in or out of the magnet.
- Three (3) people are required to perform this task.
- To perform all necessary steps for this part of the procedure,
refer to each of the illustrations that follow.

- Ensure shipping container is ready for shipment.
3 Finalization
Procedure
- Clean up the site in preparation for patient scans.
- Run head and body test scans to ensure proper operation.
