[Intl_DxMedPhys] RF shielding options for MRI (Ives Levesque, Mr)

[Steven Shea]

Dear Ives,

We have used PDC Facilities, Inc. for three different RF shielding projects
related to GE MR scanner installations. I know for at least two of them,
PDC used Laird Technologies Nickel/Copper Polyester Nonwoven Fabric for
large swaths of the room. Those installs were in 2019 for a GE Signa Artist
1.5T and in 2022 for a GE Signa Premier 3T. In both instances, I observed
final shield testing and they met GE specifications, which involves testing
at multiple different frequency bands. So far, we have not had any issues
with RF noise leaks. I can provide more details about the room designs or
other questions you might have offline.

Best regards, Steve
