Hi all,
We are using an off the shelf pcb for application in an mri. We are shielding the device using copper mesh which is removing a large part of the 64 mg hz noise that is picked up by the mri (and displayed as discrete image artifacts) but we still have a small amount of noise, again showing up as discretes. Our next step is to start looking at the components of the pcb. We do have the OEM schematics. We would like to talk to/hire someone that has had experience in this area to assist us that this point. Or possibly get some posts as to what direction we might go to mitigate the noise yet keep the pcb functioning. Thanks in advance for your help.
